New Centralized Source of Bathymetry Data

Posted on Oct 16, 2014

Northeast Ocean Data announces the release of a new centralized source of bathymetry data for the northeastern United States. Bathymetry is the measurement of water depth and the shape of seafloor terrain. Just as topographic maps represent the three-dimensional features of dry land, bathymetric maps illustrate the land that lies underwater. The new bathymetry resource page offers: data from more than 100 seafloor mapping surveys conducted with multibeam sonar, an inventory of multibeam surveys that have been planned or conducted but for which data are not yet available, a gallery featuring...

New Map of Lakes, Estuaries, Rivers, and Coastlines for Which Pollution Budgets (TMDLs) Have Been Set

Posted on Sep 26, 2014

The Northeast Ocean Data Working Group is pleased to announce that the water quality map now shows water bodies for which a Total Maximum Daily Load (TMDL) has been established. The TMDL sites shown on the map are based on a data service (last updated in August 2014) hosted by the Environmental Protection Agency (EPA). The Federal Clean Water Act requires states to identify water bodies where existing pollution controls are not sufficient to meet water quality standards and to develop a “pollution budget” designed to restore the health of the impaired body of water. This budget,...

Maps Show Predicted Habitats of Deep-Sea Corals in the Northeast

Posted on Sep 24, 2014

The Northeast Ocean Data Working Group is pleased to announce the release of maps showing predicted habitats of deep-sea corals in the northeastern United States. In this region, deep-sea corals live at depths of approximately 150 feet to greater than 6,500 feet on the continental shelf and slope. Little is known about deep-sea corals, which are of particular conservation concern because of their slow growth rates and vulnerability to disturbance. Scientists are still discovering new sites in the Northeast where deep-sea corals live, and additional locations as yet unknown are assumed to...

It provides advisory or closing information based on water quality or other environmental conditions. While this layer contains many beaches at municipal, state, and federal levels, some beaches may not be included since they are not a part of...
