Aquaculture
Topic
Aquaculture
Aquaculture data show locations of aquaculture activities in Maine, New Hampshire, Massachusetts, Rhode Island, Connecticut, and Suffolk County, New York, as well as in offshore federal waters in the Northeast. The data show shellfish management areas across the region and specific lease or license areas in Maine, New Hampshire, Massachusetts, Rhode Island, Connecticut, and Eastern Suffolk County, New York. Also included in the data are managed natural shellfish beds in Connecticut, which are additional areas of aquaculture activity in the state.

Data Considerations
The Aquaculture data should be considered a work in progress. Site data are regularly reviewed by state officials. The Portal uses the best available information provided by each state and as such reflects differences among states in how aquaculture is documented. Data users are encouraged to read the metadata. Data on shellfish management areas in each state were aggregated and classified to display areas where shellfish harvesting is approved, restricted, or prohibited on a permanent or temporary basis. In some cases, shellfish harvesting may be prohibited after rainstorms because of the likely presence of toxins that are not present under normal conditions.
Status
The Portal’s Aquaculture datasets were last updated in June 2021, in collaboration with the US Army Corps of Engineers New England District, to include the boundaries of two open water aquaculture sites in a permit application filed by Blue Water Fisheries. In 2019, the Aquaculture data were updated with the latest dataset available for New Hampshire. In 2018, datasets for Maine and Rhode Island were updated.
The Portal Working Group is reviewing Aquaculture data for needed updates.

Commercial Fishing
Topic
Commercial Fishing
Commercial Fishing includes a large amount of data on where and when different types of fishing occur, linkages between coastal communities and fishing areas, fishery management, and changes over time in commercial fishing activity. This topic encompasses five subtopics: Management Areas and Draft Alternative Management Areas depict the regulatory boundaries associated with fishing activities, whereas Vessel Activity, NOAA NEFSC Fishing Footprints, and Communities at Sea each take different approaches to representing fishing activity by leveraging different combinations of datasets (Vessel Monitoring System [VMS], Vessel Trip Reports [VTRs], vessel permit data, dealer report data) and methods (e.g., density mapping, modeling).

Communities at Sea
Communities at Sea data show linkages between fishing communities and the fishing places that are most important to them. The maps are developed by linking Federal Vessel Trip Report (VTR) data (trip dates, gear type, number of crew on board, trip locations) with vessel permit data (vessel length, ports associated with each vessel).
The relative importance of fishing areas is measured in “fisherdays” based on the number of days that vessels spent fishing in any given area and the number of crew members that were aboard. Fisherdays do not reflect other variables such as number of pounds landed, value, or other common measures of fishing activity or effort; however, the map legends use the term “fishing effort” for simplicity. The maps can be interpreted as showing community presence in ocean areas. Two types of Communities at Sea maps are available:
- Regional maps show where fishing occurs with different gear types—bottom trawl, dredge, gillnet, longline, or pots and traps—and the relative importance of different places. The dataset includes vessels from all ports. For example, the places frequented by fishing vessels using bottom trawls or dredges can be visualized separately. Regional maps are shown by default or can be viewed by selecting All Ports in the Location dropdown menu.
- Port-specific maps indicate the most important places for fishing vessels associated with a selected port. The outline on the map represents where fishing vessels from that port conduct 90 percent of their fishing activity.For example, the places frequented by fishermen from New Bedford, Massachusetts, who fish using gillnets can be mapped separately from places frequented by gillnet fishermen from Portland, Maine. In addition, the places where New Bedford vessels fish with bottom trawls can be mapped separately from places that they fish with dredges. Port-specific maps can be viewed by selecting a port in the Location dropdown menu.
Note: Data on recreational fishing can be found in Culture & Recreation.
Data Considerations
Original VTR data were obtained from NOAA NMFS Northeast Fisheries Science Center, with methodology, data processing and cartography provided by staff at Rutgers University. For information about methodology and interpretation of the data, see Creating Space for Community in Marine Conservation and Management: Mapping ‘Communities at Sea’ by Kevin St. Martin (Rutgers) and Julia Olson (NOAA). To produce the Communities at Sea maps, all data were aggregated to the community level, and none of the maps represent the fishing areas, or hot spots, of any individual fisherman or fishing vessel. Draft maps were reviewed and refined in consultation with fishermen in several ports. The following considerations and caveats guided and emerged from those conversations:
- These maps represent the locations and intensity of fishing during particular time periods. If these maps are considered during planning or permitting decision-making processes, it is critical to recognize that additional important fishing areas may not be represented, as locations frequently shift due to many factors such as market dynamics, regulatory changes, and rotational fishing strategies.
- These maps only show fishing conducted by vessels holding federal fishing permits. The maps do show a portion of state-licensed activity because many state-licensed vessels engaged in ocean fishing also hold federal permits and therefore submit VTRs. State-licensed fishing activity includes whelks (“conch”), striped bass, black sea bass, and lobster.
- Maps showing areas for fishing with fixed gear (pots, traps, gillnets) will tend to be more accurate than maps showing fishing using mobile gear (trawls, dredges), and maps showing single-day trips will tend to be more accurate than maps showing multi-day trips. This is because of the nature of the fishing activity and record-keeping regulations; fishermen are only required to report one geographic position (point location) per trip on VTRs unless switching to a new gear type or moving into a new statistical area.
- These maps can be supplemented with maps based on Vessel Monitoring System data (available for select federally managed fisheries); see the Vessel Activity subtopic of Commercial Fishing. Overlaying and comparing the VTR-based maps with VMS-based maps reveals substantial agreement between the two, and the VMS maps provide additional useful precision for some fisheries.
- Fisheries and fisheries data are complex, and there are many options for mapping fishing activity, each with strengths and weaknesses. These maps are intended as a starting point to help target and guide direct engagement and consultation with specific affected fishing communities during diverse ocean planning, permitting, and management decision-making processes.
For some types of decision making (e.g, detailed construction plans for energy infrastructure) much finer-scale information and data than can be obtained using either VTR or VMS data will be needed, ideally provided by fishermen.

Vessel Activity
Vessel Activity data broadly characterize commercial fishing vessel activity in the Northeast based on Vessel Monitoring System (VMS) data from 2006 through 2019. The relative amount of vessel activity is indicated qualitatively from high (red) to low (blue). The National Marine Fisheries Service (NMFS) describes VMS as “a satellite surveillance system primarily used to monitor the location and movement of commercial fishing vessels in the U.S.” The maps do not necessarily distinguish between fishing activity, vessel transit, and other vessel activities. Some maps show vessel activity at less than four or five knots—a speed threshold that was determined with industry input to attempt to better highlight fishing areas. Nevertheless, those maps still likely show some non-fishing activities that occur at low speeds, such as processing catch, sorting, drifting, or idling in port. The most accurate interpretation of these maps is that they indicate relative levels of fishing vessel presence for federal fisheries that require VMS monitoring. The lack of historical data and relatively short timeframe of this map preclude consideration of historical fishing areas. It also does not illustrate more recent or future changes in fishing activity resulting from changing environmental and economic conditions, fisheries management, and other important factors.
Data Considerations
The limitations of the data used to produce these maps should be understood prior to interpretation of this map. The data provided by NMFS contained the day/month/year, the geographic coordinates of the vessel at the time of transmission, speed over ground, and the vessel’s declaration code, which signifies fishery plan, program within that plan, and associated area identifier or gear-type information. These data then were aggregated by combining all program codes within each fishery plan. VMS data is subject to strict confidentiality restrictions. Therefore, the map shows the density of vessel locations following the removal of individually identifiable vessel positions. The process of removing sensitive vessel locations followed the “rule of three” mandated by NMFS Office of Law Enforcement (OLE). The details of this filtering process vary between individual data products; see the metadata for each layer to see more detail on filtering processes used. A statistical method to normalize data was used on the subsequent density grids and data values represent standard deviations. While legends are consistent across products, values represent high or low areas of vessel activity specific to each dataset. This process can result in the maps showing vessel activity that seems anomalous, e.g. single data points in areas where multispecies fishing isn’t common, because three data points occur in a given 100m by 100m square. This is usually because of transit lines that overlap in a given cell while nearby cells contain less than three data points.
Status
Data through 2019 were updated and posted on Northeast Ocean Data in fall 2022, and they will continue to be updated as described in the 2016 Northeast Ocean Plan.

NOAA NEFSC Fishing Footprints
NOAA NEFSC Fishing Footprints data depict areas of commercial fishing activity categorized by gear type, fishery (FMP), and time period and measured by landings or revenue. The data combine Vessel Trip Report (VTR) and dealer report data with modeling of probable fishing location using observer data.
Data Considerations
Data provided comply with data confidentiality requirements under the Magnuson-Stevens Act through aggregation. The data was summarized to show fishing activity in terms of pounds of fish landed (“landings”) or value (“revenue”) by Fishery Management Plan (FMP), species, fishing gear type, and time periods. Data was summarized on a 500 x 500-meter grid, showing activity within each grid cell. For more information on the Fishing Footprints methodology, please see DePiper G.S. 2014. Statistically assessing the precision of self-reported VTR fishing locations. NOAA technical memorandum NMFS-NE-229 and Benjamin S, Lee MY, DePiper G. 2018. Visualizing fishing data as rasters. NEFSC Ref Doc 18-12; 24 p.
Revenue and landings have been summarized for two time periods (2011-2015 and 2016-2020) for both FMP and gear type. The values represent annual averages over each five-year period. The data shown on the Northeast Ocean Data Portal has been filtered from the original data. Areas where revenue was less than $25 was excluded from both the revenue and corresponding landings data. Additionally, some of the “other” gear types with very little fishing activity were excluded from this set of data. Data are grouped into categories for time period, gear type/FMP, and revenue/landings.

Management Areas
Management Areas data show the boundaries of dozens of federal and state fishery management areas implemented for fisheries such as groundfish, lobster, sea scallop, and herring. Management areas data are organized by managed fishery.
Data Considerations
Management areas are regulatory boundaries that can change over time. Portal users should always consult the source/authority to verify the timeliness of the data prior to interpretation/use. For this same reason, Portal users should be careful to interpret ocean use/activity data that may correspond to times when different management areas were in effect. For example, the Atlantic scallop fishery is managed using a set of areas that rotate in terms of open/closed status every few years. Users should take care to interpret scallop fishery activity data with the management areas data that depict the management scheme in place during the applicable time. See “Expired Management Areas” for data depicting management areas that are no longer in effect but for which activity data may be present on the Portal.
Status
Data were reviewed for completeness and accuracy in 2023.

Topic
Fish
Fish data provide information about fish species distribution, abundance, biomass, and habitat suitability in the northeast region. The data products within this topic are derived from state and federal surveys that have been repeated at regular intervals over time. This repetition has allowed NROC and its partners to develop maps that show shifts in species distribution over time using time-sliders and other tools. This topic also includes datasets that show the extents or footprints of some of the long-term surveys conducted by NOAA Fisheries, states, and other groups.

Federal and Coastal Trawls by Species
This subtopic contains layers depicting the distributions of over 80 individual fish species based on their presence in repeated trawl surveys throughout the northeast region.
Federal trawl data come from the NOAA Northeast Fisheries Science Center, which has conducted the spring and bottom trawl survey since 1963. Federal trawl data products are bubble plots of raw observations and inverse-distance-weighted (IDW) surfaces at a 2km x 2km resolution for fall and spring survey data from 2010-2019 (records for fall 2017 were removed due to incomplete coverage of the survey area). All units are kilograms per tow. The IDW surfaces were developed using methods jointly developed by NOAA Fisheries and the Pinksy Lab at Rutgers University.
Coastal trawl data are provided by the Northeast Regional Habitat Assessment (NRHA), which is led and conducted by the New England Fishery Management Council and Mid-Atlantic Fishery Management Council with support from the NOAA Fisheries Office of Habitat Conservation and Office of Science and Technology. NRHA products in the Portal include summaries of abundance from 2010-2019 for approximately a dozen common coastal species derived from several coastal trawl datasets contributed by states and others. Hexagons are used to summarize abundance across the study area (Maine to Florida).
Data Considerations
Each set of fish trawl data sources has used standardized survey designs and data collection methodologies, but some have used different vessels and gears over time. Results have been normalized to account for these vessel and gear differences within each data source. These data products are based on observed data, not model predictions, for the selected time period.
For more detail about the mapping approaches and methodologies for the NEFSC (Federal) data products, including information about vessels, gear types, and species catchability, see the MDAT Technical Report on the Methods and Development of Marine-life Data. The raw data used to develop these data products are available in the NOAA InPort System: Bottom Trawl Surveys. Similar data products for additional time periods for the NEFSC bottom trawl survey and federal bottom trawl surveys in other U.S. regions can be explored via NOAA’s Distribution Mapping and Analysis Portal (DisMAP). DisMAP also includes visualizations of fish biomass change over time and a number of other distribution metrics.
Users interested in additional detail about the NRHA (Coastal Trawls) data should visit the NRHA Data Explorer. The NRHA Data Explorer includes maps, graphs, visualizations, and model outputs for many more individual species, as well as trawl survey metadata and other fish species information. The NRHA Data Explorer is a data viewer for trawl surveys. The data are not available for download. Datasets displayed on this site in summary format have associated caveats related to the collection of these data and their use. Please refer to the NRHA Reports page for additional details on each dataset, including contact information to obtain the source data. NRHA did not create the data and cannot guarantee its accuracy, or its suitability for use for other applications. NRHA encourages proper use and attribution of any datasets summarized on this site. Interested parties should directly contact the data providers noted in the NRHA metadata inventory for additional details on these data and their proper use.
Portal maps represent one set of many available sources of information, and in many cases only show subsets of full datasets that inform our current understanding of fish species distribution and abundance in the Northeast region. Other sources of information on fish species that complement the data shown here include:
- NOAA’s Distribution Mapping and Analysis Portal (DisMAP),
- The Northeast Regional Habitat Assessment Data Explorer
- OceanAdapt, a collaboration between the Pinsky Lab of Rutgers University and the NOAA National Marine Fisheries Service to provide information about the impacts of changing climate and other factors on the distribution of marine life,
- fishery-dependent data, such as fisheries observer data, vessel trip reports, or vessel monitoring systems (VMS) data,
- federal- and state-based river herring monitoring,
- vessel trip reports for lobster fishing,
- dedicated federal/academic/industry surveys of sea scallops, and
- the Northeast fish and shellfish climate vulnerability assessment.

Archived Coastal Trawls Data
This subtopic contains layers depicting the distributions of over 80 individual fish species based on their presence in repeated trawl surveys throughout the northeast region from 2005-2014. (More recent datasets are contained in the Federal and Coastal Trawls by Species subtopic.)
Archived Coastal Trawl data were produced by the Marine life Data and Analysis Team (MDAT) and the Portal Working Group in collaboration with the NOAA Northeast Fisheries Science Center, Massachusetts Division of Marine Fisheries (MDMF), North East Area Monitoring and Assessment Program (NEAMAP), Maine & New Hampshire state trawls (ME/NH), and Connecticut Department of Energy and Environmental Protection Long Island Sound trawl (LIS).
For each of more than 80 species, the data products include bubble plots of raw observations and a 10km x 10km inverse-distance weighted interpolation plot which smoothed over multiple observations and interpolated in regions with few observations. All units are natural log kilograms per tow.
Data Considerations
These data are considered “archived” because they represent observed biomass from 1978-2014 and more recent fish distribution data are now available under Federal and Coastal Trawls by Species.
Each set of data sources have used standardized survey designs and data collection methodology, but some have used different vessels and gears over time. Results have been normalized to account for these vessel and gear differences. Fall survey samples were collected primarily from September to November, and spring survey samples were collected primarily from February to April. These data products are based on observed data, not model predictions, for the selected time period.
For more detail about the available time periods, mapping approaches, and other methodologies, including information about vessels, gear types, and species catchability, see the MDAT Technical Report on the Methods and Development of Marine-life Data.

Federal Trawl Summary Products
This subtopic contains Summary Products depicting the distributions of groups of fish species based on their presence in the spring and fall bottom trawl conducted by the NOAA Northeast Fisheries Science Center between 2010-2019. Species groups were developed through a partnership with the Marine life Data and Analysis Team (MDAT) and fall into several categories:
- Ecological (Diadromous, Forage, Demersal)
- Managed Species (NEFMC multispecies, NEFMC small mesh multispecies, NEFMC skates)
- Stressor Groups (Abundance vulnerable to climate changes, Distribution vulnerable to climate changes, Potentially vulnerable to EMF)
For each of these species groups, users can view biomass and species richness summarized for 2010-2019. Also within this subtopic are Historical Summary Products for all of the species groups listed above. Users can view spring and fall biomass Summary Products by decade between 1980 and 2019.
Data Considerations
Federal Trawl Summary Products provide a general overview of the total biomass or number of species (richness) for groups of species that are similar because of the way they are managed, their ecology, or their sensitivity to specific stressors. The Northeast Regional Ocean Council’s Marine Life Work Groups, stakeholders, the Ecosystem Based Management Work Group, and similar proceedings in the Mid-Atlantic region helped determine what Species Groups should be mapped and what species should belong to each group.
Species Group products can help answer questions such as:
- Where do the highest number of managed species overlap? (Species of Concern)
- Where are demersal fish most abundant? (Ecological Group)
- Where are fish that are potentially vulnerable to EMF most abundant? (Stressor Group)
Species Group products show annual averages of species patterns, they group as many as 81 species together on a single map, and they do not have specific associated estimates of uncertainty. For these reasons, Species Group products are a good starting point for further detailed analyses and exploration of the Individual Species products on which they are based.
To address specific questions, users should explore Individual Species map products. The entire marine life virtual reference library contains extremely detailed spatial and temporal information, including several measures of uncertainty to supplement each individual species map. These data are well suited to address specific questions in conjunction with site-specific data, scientific literature, public input, and many other information sources. For more details about mapping approaches, specific methods, caveats, and limitations, see the Marine-life Data and Analysis Team Model Repository.

Highly Migratory Species Habitat Suitability – Past and Future
These data products were developed as part of the NASA-funded Fisheries and Climate Toolkit (FaCeT, https://fisheriesclimatetoolkit.sdsu.edu). FaCeT is a set of products to visualize and explore how climate change will impact highly migratory marine species and fisheries, bridging the gap between fisheries and climate science to support climate resilient and sustainable fisheries.
Data Considerations
Past and future habitat suitability for highly migratory species are modeled data products that leverage several input datasets. Species occurrence was represented using two fishery-dependent datasets: a tag database from the International Commission for the Conservation of Atlantic Tunas Secretariat and catch data from the at-sea observer program that monitors the U.S. Atlantic pelagic longline fishery. Several oceanographic data and models were used as potential predictor variables in the species distribution models. All of the oceanographic datasets were plotted, coarsened, or interpolated to match a grid with a ~9km horizontal resolution. Data were derived from the Global Ocean Physics Reanalysis (GLORYS) for observed oceanographic conditions (1993-2019) and Regional Ocean Model System (ROMS) simulations of the Northwest Atlantic ocean for future oceanographic conditions (2070-2099):
- Monthly sea surface temperature, degC
- Monthly sea surface height (meters)
- Monthly sea surface salinity (PSU)
- Bathymetry (meters) – from ETOPO1
- Rugosity (meters) – from ETOPO1
Full details for data processing and quality control can be found in Braun et al., 2023a and implementation of those methods for climate-scale projections is detailed in Braun et al., 2023b.

Bathymetry & Seafloor
Topic
Bathymetry & Seafloor
Bathymetry & Seafloor datasets relate to the shape, composition, biological activity, and depth below the sea surface of the seafloor. Bathymetry and seafloor data are used for navigational safety and charting, scientific research, and ocean planning. Data collected for navigational safety purposes must adhere to a specific set of standards and QA/QC procedures, whereas data collected for science and planning may not need to meet such rigorous criteria. Users should consult the metadata for each data product to understand intended uses. The data products within this topic are derived from many individual state, federal, and private sources. Within Bathymetry & Seafloor, Portal users can explore several subtopics.

Subtopic
Seafloor Features & Geoforms
Seafloor features and geoforms data products are usually derived from some combination of bathymetry data and “ground-truthing” data (e.g., sediment samples, images of the seafloor). The Coastal and Marine Ecological Classification Standard (CMECS) is a structured catalog of ecological terms that also provides a framework for interpreting, classifying, and inter-relating observational data from all types of sensors and platforms. CMECS Geoform units describe the major geomorphic and structural characteristics of the coast and seafloor.
Data Considerations
The quality and accuracy of seafloor features and geoforms data products depends heavily on the quality of the input data. Users should consult the metadata for each data product to obtain data provider contact information, methodological detail, and to understand intended uses.
Many types of seafloor features and geoforms are static on long time scales (e.g., rocky zone), whereas some (e.g., sediment wave field) may be dynamic on much shorter time scales. Broadly, the extent of seafloor features and geoforms are thought to be mostly stable on decadal time scales. However, the exact extent and location of these features today may differ slight than those shown in the Portal.
Status
The data products and sources within this topic were reviewed by the NROC Habitat Classification and Ocean Mapping Subcommittee in 2025.
Examples of Data
- Seascapes – CMECS Geoform Category 1
- TNC NAMERA Seabed Forms
- Submarine Canyons
Subtopic
Sediment Products
Sediment data products represent the surficial composition of the seafloor, usually expressed as “grain size” or a classification of grain size (e.g., “sandy mud”). The Coastal and Marine Ecological Classification Standard (CMECS) is a structured catalog of ecological terms that also provides a framework for interpreting, classifying, and inter-relating observational data from all types of sensors and platforms. CMECS Substrate units describe the character and composition of surface and near-surface substrates.
Sediment data are collected by federal, state, and private entities. Some databases of sediment in the northeast U.S. include descriptions that are 200 years old.
The sediment data products in the Portal include point datasets of individual sediment observations as well as continuous models or maps of sediment types that are built using the sediment observations as one of many potential inputs.
Data Considerations
The quality and accuracy of sediment data and data products depends heavily on the age, collection method, and in the case of continuous models – the modeling methods and quality of the input data. Users should consult the metadata for each data product to obtain data provider contact information, methodological detail, and to understand intended uses.
Some seafloor environments in the northeast U.S. are more stable than others. Users can overlay data products that estimate sediment stability (Sediment stability, N m-2 (SMAST)) to understand how to potentially interpret a map of sediment types for a particular location.

Subtopic
Fishing Effects
The datasets in this subtopic constitute the sediment data inputs and primary outputs from the Northeast Fishing Effects Model (Fishing Effects). Fishing Effects estimates the impacts of fishing with bottom-tending gears on seabed habitats throughout the Northeast region in both state and federal waters within the U.S. EEZ. Habitat impacts vary in space and time according to fishing gear type, the magnitude of fishing effort in each grid cell, and the types of geological and biological habitat structures inferred to each grid cell. These habitat structures are inferred based on substrate type and natural energy at a particular location. The types of structures assumed to occur in each grid cell influence the estimated susceptibility of the habitat to fishing and the estimated recovery times following impact.
The Fishing Effects model is based on the Swept Area Seabed Impact (SASI) model (NEFMC 2011) and a model developed by the North Pacific Fishery Management Council (Fujioka 2006). The SASI vulnerability assessment was published in 2014 by Grabowski et al. Fishing Effects is also used in the North Pacific region (Smeltz et al. 2019), and Fishing Effects Northeast was developed in collaboration with the developers of Fishing Effects North Pacific. The Fishing Effects Model was developed collaboratively by the New England Fishery Management Council’s Habitat Plan Development Team and the Fisheries, Aquatic Science, and Technology Laboratory at Alaska Pacific University.
Data Considerations
The primary purpose of the sediment maps is to serve as a base layer for the Fishing Effects model. Five different sediment grain sizes plus a steep and deep habitat type are represented in the dataset, which indicates the proportion of each grain size occurring within each 5×5 km grid cell based on available data (primarily from the USGS and SMAST drop camera survey dataset).
The Portal shows monthly model outputs for the 3 most recent years available (2015, 2016, 2017). The Fishing Effects model generated monthly data for 1996-2017.
Positional accuracy may vary according to positioning methodology in the underlying data sources. Note that Vessel Trip Reports often represent each fishing trip by a single latitude/longitude. Results are aggregated by Fishing Effects Model grid cell, with each cell having a resolution of 5×5 km.
The products are based on sediment samples collected between 1934 and 2018 and fishing activity occurring between 1996 and 2017.
There is no formally established threshold percentage indicating severe or significant vulnerability in a management context. In considering how these model outputs relate to real-world fishing activity, it is important to recognize that while fishing is distributed broadly across the Northeast-shelf region, activity with specific gear types is typically concentrated spatially. The percent disturbance results can be contrasted with the intrinsic vulnerability results to get a sense of the difference between the expected effects from moderate, uniform levels of fishing as compared to the percentages of disturbance that result from real-world concentrations of effort. Because the Fishing Effects model allows for recovery from disturbance, the percent disturbance will eventually trend toward zero in the absence of fishing effort, and locations with no effort from a particular gear type (fishery closure areas, or locations where that gear is simply not used) will show no disturbance associated with that gear.
Users should consult the metadata for data provider contact information, a detailed description of the Fishing Effects methods, and to understand intended uses.
Status
Fishing Effects Northeast was last updated in 2019, and another update is planned as part of the New England Council’s 2025 EFH Review.

Navigation
Navigation data products shows boundaries of designated and identified marine transportation areas for commercial and recreational vessels in the region.
Data Considerations
Many of the features on the Navigation map are officially designated and actively maintained by the U.S. Coast Guard or the U.S. Navy, and their locations are well established. Examples include anchorages; maintained channels; safety, security, and regulated zones; danger zones and restricted areas; and boundaries of the Mandatory Ship Reporting System. Some of the pilot boarding areas on the map are not designated by federal or state government authorities. However, they are well known and considered important by the maritime commerce sector.
Examples of Data
- Traffic Lanes
- Danger Zones Restricted Areas
Subtopic
Commercial Traffic
This map series shows the vessel transit counts or relative density of large commercial cargo, tanker, tug-tow, passenger, fishing, recreation, other, or all vessels in 2011-2013 and 2015-2024. These maps are based on data received from Automatic Identification Systems (AIS). Maps generally show the annual vessel activity; for select years and vessel types, maps also show monthly activity.
Data Considerations
Not all vessels are equipped with AIS, nor are all vessels required to carry and operate an AIS. AIS utilizes radio frequency transmissions, and therefore the effective range at which a vessel can be detected can vary widely based on atmospheric conditions and equipment configuration. For these maps, vessel tracks were derived from raw AIS data provided by the U.S. Coast Guard. The vessel tracklines were used to generate transit counts or density values to convey patterns of vessel activity by vessel type.
The datasets may contain errors in vessel categorization. For example, some vessel operators did not report their vessel type or reported the wrong category by mistake, and some vessels are used for multiple purposes but are included in only one AIS category (e.g., a boat categorized as a pleasure craft that also operates as a fishing vessel). In addition, while every effort is made to ensure data quality, occasional errors can occur in processing these data.

Marine Mammal Density by Species
This subtopic contains layers depicting the monthly distributions of 31 individual marine mammal species or guilds based on their presence in structured scientific surveys in the Atlantic Ocean. Layers represent predicted densities for each month considering surveys conducted and environmental conditions observed between 1992 and 2020.
Models for individual marine mammal species and guilds were developed by the Marine Geospatial Ecology Lab (MGEL) at Duke University through a partnership with the Marine-life Data and Analysis Team (MDAT) and a collaboration with the Northeast Regional Ocean Council and expert work groups. MGEL worked with marine mammal biologists and ecologists at the NOAA Northeast and Southeast Fisheries Science Centers and several other research institutions to create habitat-based density surface models for cetaceans occurring off the US East Coast. The results of this work have been published in Roberts et al. (2016), with updates documented in Roberts et al. (2023).
Data Considerations
Some of the MDAT maps contain information about federally protected species. Additional information about the distribution, abundance, and range of species listed under the Marine Mammal Protection Act, the Endangered Species Act, the Migratory Bird Treaty Act, and the Magnuson-Stevens Fishery Conservation and Management Act is available at:
- NOAA Fisheries Office of Protected Resources
- NOAA Fisheries Greater Atlantic Region Protected Resources Division
- NOAA Fisheries Office of Habitat Conservation
- NOAA Fisheries Greater Atlantic Region Habitat Conservation Division
Details about each individual model can be found on the MGEL Seamap Model Repository page, along with some animations and answers to frequently asked questions. The MDAT Technical Report on the Methods and Development of Marine-life Data summarizes additional aspects of the models that may be important to users of Northeast Ocean Data. These maps represent one set of many available sources of information that inform our current understanding of species distribution and abundance in the Northeast region. Other sources of information on marine mammal species that complement the data shown here include:
- the Atlantic Marine Assessment Program for Protected Species (AMAPPS) and AMAPPS Marine Mammal Model viewer,

VAMSC surveys in Virginia were funded by the Virginia Coastal Zone Management Program at the Department of Environmental Quality through Task 1 of Grant NA12NOS4190027 and Task 95.02 of Grant NA13NOS4190135 from NOAA, under the Coastal Zone Management Act of 1972, as amended. The southeast U.S. right whale surveys were funded by NOAA, the U.S. Army Corps of Engineers, the U.S. Coast Guard, the U.S. Navy, the Georgia Department of Natural Resources, the South Carolina State Port Authority, and the National Fish and Wildlife Foundation. Funding for this project was provided by United States Fleet Forces Command and was managed on their behalf by Naval Facilities Engineering Systems Command Atlantic. Development of the model for North Atlantic right whale was co-funded by NOAA under a cooperative research agreement. The Northeast and Mid-Atlantic Regional Ocean Councils provided funding for summary product creation and data hosting services.

Subtopic
Marine Mammal Summary Products
This subtopic contains Summary Products depicting the total abundance and species richness of several different groups of marine mammals. It was built from the Marine life Data and Analysis Team (MDAT) Individual Species products (available in the Marine Mammal Density by Species subtopic) that characterize the predicted distribution and abundance of marine mammal species or species guilds. Species groups were developed through a partnership with MDAT and fall into several categories:
- All cetaceans
- Ecological groups (Baleen whales, Sperm and beaked whales, Small delphinoids, Large delphinoids)
- Species of concern (All ESA-listed species)
- Stressor groups (Low frequency sound sensitivity, High frequency sound sensitivity, Vulnerability to climate change, Sensitivity to climate related changes in abundance, ensitivity to climate related changes in distribution, Sensitivity to climate related changes in phenology)
For each of these species groups, users can view total abundance and species richness summarized for a typical annual period.
Data Considerations
Species Group products provide a general overview of the total abundance, biomass, or number of species (richness) for groups of species that are similar because of the way they are managed, their ecology, or their sensitivity to specific stressors. Experts convened by NROC and MARCO helped determine what Species Groups should be mapped and what species should belong to each group.
Species Group products can help answer questions such as:
- Where do the highest number of endangered whale species overlap? (Species of Concern)
- Where are small delphinoids most abundant? (Ecological Group)
- Where are mammals that are sensitive to low-frequency sound most abundant? (Stressor Group)
Species Group products show annual averages of species patterns, they group as many as 31 species and species guilds together on a single map, and they do not have specific associated estimates of uncertainty. For these reasons, Species Group products are a good starting point for further detailed analyses and exploration of the Individual Species products on which they are based.
To address specific questions, users should explore the Marine Mammal Density by Species subtopic. The entire marine life virtual reference library contains extremely detailed spatial and temporal information, including several measures of uncertainty to supplement each individual species map. These data are well suited to address specific questions in conjunction with site-specific data, scientific literature, public input, and many other information sources.
For more details about mapping approaches, specific methods, caveats, and limitations, see the Marine-life Data and Analysis Team Model Repository page.

Subtopic
Federally Managed Natural and Historical Areas
Data within this subtopic include sites and areas listed in the National Register of Historic Places, proposed and existing National Marine Sanctuaries, National Parks, and other federally managed lands. The National Register of Historic Places (NRHP) was established by the National Historic Preservation Act of 1966. The NRHP database is a listing of sites (e.g., buildings, objects) and areas (e.g., large properties, districts) that have cultural or historical significance and are noteworthy for preservation.
Data Considerations
The National Register of Historic Places dataset is a compilation from state databases. Currently the map shows NRHP locations only in Maine, Massachusetts, New York, and Rhode Island. NRHP data for New Hampshire and Connecticut are not shown on the map because spatial datasets for those states are currently being developed. The NRHP sites in this dataset are from individual state databases/sources. Some NRHP sites may be missing from this dataset. However, states are working on updating their databases/datasets, and this regional dataset will be updated as states provide updates. Users must consult with appropriate State and/or Tribal Preservation Offices in the identification and evaluation of historic properties as stated under the National Preservation Act. This regional dataset compiled by Northeast Ocean Data serves as a baseline for identifying NRHP; users must confirm with appropriate State and/or Tribal Preservation Offices for official listings under the National Register of Historic Places. For more information and current listings of NRHP, please be directed to the National Park Service’s National Register of Historic Places website.
Status
NRHP data were current as of 2015. Other datasets within this subtopic were reviewed in 2024 and 2025.

Subtopic
Secured Lands
Data in this subtopic are a subset of The Nature Conservancy’s 2018 Secured Lands dataset (publicly downloadable external version), including State Forests, Lands, and Parks within ten kilometers of the coastline from Maine to New York. The complete version of the Secured Lands dataset is available at http://nature.ly/securedareas with a detailed report and additional information. The Secured Lands dataset shows public lands, private lands, and waters secured by a conservation situation that includes an explicit level of security from future conversion and current incompatible uses.
Data Considerations
The Nature Conservancy strives for its Secured Lands dataset to include all permanently protected lands in the eastern 18 U.S. states. The dataset is compiled annually from over sixty sources. For the most part, it is a combination of public land information maintained by each state, and private conservation land information compiled by The Nature Conservancy’s state field offices. Please see metadata for more information. Please be advised that not all sites found in The Nature Conservancy’s Secured Lands dataset and the dataset provided on the Northeast Ocean Data Portal are publicly accessible.
Status
Final dataset leverages a 2018 database from The Nature Conservancy; reviewed in 2025.

Subtopic
Boating
The Boating map depicts activity areas mapped through two separate but related studies. Recreational Boating Density and Recreational Boater Routes result from the 2012 Northeast Recreational Boater Survey conducted by SeaPlan, the Northeast Regional Ocean Council (NROC), states’ coastal agencies, marine trade associations composed of many private industry representatives, and the U.S. Coast Guard First District. Distance Sailing Races were characterized as part of the Northeast Coastal and Marine Recreational Use Characterization Study which was conducted by SeaPlan, the Surfrider Foundation, and Point 97 under the direction of the Northeast Regional Planning Body.
Data Considerations
Both a random and a supplemental sample of Northeast boaters plotted their boating routes throughout the 2012 boating season using an online mapping application. The density map is derived using only the random sample of survey participants and is intended to show the relative density of boating activity throughout the region using a scale from high (red) to low (green). Areas showing low or no activity does not necessarily mean they are not used for recreational purposes. According to the results of the survey, these areas are likely less trafficked than other areas. Distance sailing race routes were mapped through a combination of online research, existing datasets such as the Rhode Island Ocean Special Area Management Plan (RI OSAMP), and industry expert data mapping and vetting. This dataset is believed to represent all known and believed-to-be recurring offshore distance sailing races in the region, as defined by the scope of this study. This study defined a distance sailing race as an offshore race starting at one port and ending in another, or an offshore race which begins at a port, has a turning point at a single location, and ends at the same port. This dataset is not intended to capture the spatial footprint of buoy races, which typically take place closer to shore and whose courses include sailing around courses comprised of buoys or other navigational markers. The lines depicting these races are highly generalized to reflect an approximate route between the start and end locations, based on course instructions, information from industry experts, and data from race tracking software. There can be a large spread of boat routes associated with any one race and these lines are meant to depict a general midpoint of activity and as such, this dataset is intended to be depicted at a regional scale. Actual sailing routes vary depending on winds and other environmental conditions, meaning that races depicted on a large (i.e., zoomed-in) scale may not provide a precise depiction of the actual race activity.
Status
These are final data products, representing the results from a 2012 recreational boater survey.
Examples of Data
- Recreational boating density
- Recreational boater routes
- Distance sailing races
Subtopic
Whale Watching
Whale watching layers depicts areas mapped by whale watch industry experts in 2020, using the Northeast Coastal and Marine Recreational Use Characterization Study (conducted in 2015 by SeaPlan, the Surfrider Foundation, and Point 97 under the direction of the Northeast Regional Planning Body) as a starting point. Whale watch owners, operators, naturalists, and data managers attended multiple webinars to review and discuss updates to the original data to best depict where whale watching takes place in the region, while also providing information about seasonality, species, and overall industry trends. Experts generally sought to depict whale watching activity in the last decade (2010-2020) by highlighting areas of general use, dominant use, supplemental areas, and transit routes. RI Ocean Special Area Management Plan areas were mapped as part of the Rhode Island Ocean Special Area Management plan and are symbolized separately to reflect different data collection methodologies.
Data Considerations
This map also shows the locations of whale watching entities in the region who have been invited to participate in data development and review. Clicking on the point locations will reveal the name of the entity, its location, and website URL. Users are encouraged to consult the metadata for additional details.
Status
These are final data products, representing the results of an expert working group in 2020.
Examples of Data
- Commercial Whale Watching Areas

Subtopic
SCUBA
SCUBA diving data were collected through several methods which include outreach to the SCUBA diving community and mining existing data sources. Data were initially collected as part of the Northeast Coastal and Marine Recreational Use Characterization Study which was conducted by SeaPlan, the Surfrider Foundation, and Point 97 under the direction of the Northeast Regional Planning Body from 2014-2016. Additional dive site data from the REEF voluntary fish survey were added in 2021 and updated in 2023.
Data Considerations
This map depicts generally well-known SCUBA diving areas, such as wrecks, artificial reefs, and other marine habitats, as mapped by SCUBA diving experts and locations identified in online and published SCUBA guides and associated literature. While the dataset is thought to provide a thorough representation of where SCUBA diving is likely to take place in the region, it does not purport to represent the location of every location where SCUBA diving could take place. While man-made structures, such as wrecks and artificial reefs are finite in number, there are additional, enumerable sites that, while important to divers, may lack specific boundaries and which might not be known by many divers. Some locations have been buffered to address data confidentiality and site sensitivity concerns.
Status
These are final data products, representing data compiled in the early 2020s.
Examples of Data
- Recreational SCUBA Diving Areas
- REEF Dive Sites and Reports
