The National Oceanic and Atmospheric Administration’s Deep Sea Coral Research and Technology Program convened a two-day science priorities workshop on May 2-3, 2023 to build partnerships and set research priorities for the program’s four-year (2023-2026) Northeast Deep-Sea Coral Initiative.

The National Oceanic and Atmospheric Administration's Deep Sea Coral Research and Technology Program compiles, curates, and makes public a National Database of biogeographic data and information on deep-sea corals and sponges. This report details developments and enhancements to the database since it became accessible through the online portal in 2015.

This is a comprehen­sive, up-to-date guide, detailing 161 coral taxa identified from museum collections, primary literature, and video records. The guide provides informa­tion for targeting new collections and identifying areas of high abundance and indicator species of vulnerable marine ecosystems.

This report summarizes the objectives, accomplishments, and outcomes of NOAA's West Coast Deep-Sea Coral Initiative, funded by the Deep Sea Coral Research and Technology Program. The four-year initiative (2018-2021) was designed to explore, map, characterize, and conduct research on deep-sea coral and sponge habitats in the Pacific Fishery Management Council region, inclusive of waters off California, Oregon, and Washington.

In Flower Garden Banks National Marine Sanctuary region within the northwestern Gulf of Mexico, sponges thrive among diverse biological and geological habitats between 16–200+ m deep (i.e., coral reefs and communities, algal nodules, and coralline algae reefs, mesophotic reefs, patch reefs, scarps, ridges, soft substrate, and rocky outcrops). A synoptic guide is presented, developed by studying common sponge species in the region, through direct sampling and in-situ photographic records. This work improves our knowledge of Gulf of Mexico sponge biodiversity and highlights the importance of the region for scientists and resource managers.

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.

The purpose of this science plan is to outline a general strategy for the execution and completion of the most important research activities conducted under the Alaska Deep-Sea Coral and Sponge Initiative (AKCSI). The plan outlines the general approach and proposed research. Research projects supported by the 2020-2023 AKCSI will consist of the following:

• Research expeditions that survey, sample, and map DSCS ecosystems throughout the Alaska
  region.
• Research projects focused on deep-sea coral and sponge data and analyses of survey samples.
• Deliverables that support the goals of AKCSI and the Deep Sea Coral Research and Technology Program.
