Latest On The Conservation Gateway

A well-managed and operational Conservation Gateway is in our future! Marketing, Conservation, and Science have partnered on a plan to rebuild the Gateway into the organization’s enterprise content management system (AEM), with a planned launch of a minimal viable product in late 2024.

Viewed from shore, the ocean might seem like an endless blue-grey expanse stretching into the horizon - one monolithic pool of salt water and sea foam. But beneath the murky surface lies underwater terrain as varied and complex as the land itself, with waters teeming with biological diversity that tests the bounds of imagination.

To understand the complex marine environment and to ensure it is healthy and sustainable for the future, TNC has conducted various regional assessments and research projects to map the resources and processes existing across our region. With this knowledge, we gain understanding on how these systems change.  It also informs efforts to conserve and sustain these ecosystems.

Marine Assessments

With regional assessments, scientists map seafloor habitats and coastal ecosystems, identify key areas for the conservation of marine fish, marine mammals, and sea turtles, and map the varied human uses of the ocean. All this information is then combined to find a balance between resource use and conservation of natural diversity through Marine Spatial Planning. 
We organized these assessments into three regions that correspond to the U.S. regional planning areas:

-Northwest Atlantic Marine Ecoregional Assessment (NAMERA), visit page
-Long-Island Sound Ecoregional Assessment (LISEA), visit page

-Delaware River Basin Conservation Initiative, visit page
-Northwest Atlantic Marine Ecoregional Assessment (NAMERA shared with NW region), visit page
-Long-Island Sound Ecoregional Assessment (LISEA shared with NW region), visit page
-South Atlantic Bight Marine Assessment (SABMA), visit page

Other Research

While not related to regional assessments, TNC has also conducted or managed projects in the Atlantic that provide more information various aspects of these complex ecosystems. These projects include:
