This report summarizes fiscal year 2020 and 2021 activities that supported management decisions, improved our understanding of deep-sea coral and sponge communities, and leveraged partnerships to enhance operational efficiency and effectiveness. Operating through NOAA Fisheries’ Office of Habitat Conservation, and funded at approximately $2.3 million annually to support national-scale research, the Program collaborates widely and leverages substantial funding to study the role of corals in support of deep-sea ecosystems.

Have you ever wondered what the seafloor looks like in Alaska? Join us to learn about Alaska's deep-sea coral and sponge habitats, how we study them, and what it's like to be a student intern with NOAA's Deep Sea Coral Research Technology Program.

Shore-based submersible operations, from 2006 to 2020, have allowed us to examine megabenthic assemblages along the island margin of Isla de Roatán from depths of about 150 to 750 m, including repeated observations of the same organisms. These dives were used to photo-document a diverse benthic assemblage and observe the health and condition of the sessile fauna in a well-explored but relatively undocumented area of the Mesoamerican Reef.

This study analyzed alpha and beta diversity of mesophotic coral forests on fourteen topographic banks in the northwestern Gulf of Mexico. The objective of the study was to examine differences in structure and community in relation to lease stipulations established by the Bureau of Ocean and Energy Management.
