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. If you’re interested in learning more about the project, reach out to for more info!

Offshore Video Survey and Oceanographic Analysis: Georges Bank to the Chesapeake (SMAST)

For this project, ten years (2003–2012) of data from the SMAST scallop survey and NECOFS were used to create new products describing the benthic habitat, benthic animal abundance and distribution and the environmental conditions in the survey area. Layers are organized by task, from 1 to 5 (see report for more details).
