- Quick access to the best available hydrographic-quality bathymetry data downloads via NCEI, through an interactive Data Explorer map showing the footprints of bathymetric surveys (see image below). This interactive map layer can be added to any Data Explorer map or users can access the map link from the Bathymetry page or the Data Downloads page. Clicking on any survey footprint will reveal the data download link in a popup window.

- Aggregation of the best available high-resolution local and regional bathymetry data and other associated seafloor mapping datasets for the Northeast U.S.
- Compilation of national-scale bathymetry, hydrography, and coastal topography data and resources from NOAA, US Army Corps of Engineers, and USGS
- Collection of information and resources about hydrographic survey and seafloor mapping planning
The new Bathymetry pages will continue to be updated as new data and resources are developed and added to Portal maps.
In addition, several groups of experts led by the Northeast Regional Ocean Council (NROC) or with NROC participation are continuing to advance the collection, compilation, synthesis, sharing, and uses of regional bathymetry and seafloor habitat data. Learn more about each of those efforts by visiting the links below.
