Deepwater Atlantic Habitats II: Continued Atlantic Research and Exploration in Deepwater Ecosystems with Focus on Coral, Canyon and Seep Communities (AT41) Overview Map

The AT41 expedition on board the RV Atlantis with the DSV Alvin is the first submersible sampling cruise of the Deep SEARCH project. This cruise occurred from August 19 to September 02, 2018. The cruise will focus on several seep sites, canyons, and hard bottom features located less than 100 nm offshore. This is the third research expedition associated with the Deep SEARCH project focused on exploring and characterizing seeps, corals, and canyon environments along the Atlantic margin. This project is a collaboration among three federal agencies: Bureau of Ocean Energy Management (BOEM), NOAA Ocean Exploration, and the U.S. Geological Survey (USGS). TDI Brooks with academic partners has been selected to serve as BOEM contractor for this study. Data gathered during this mission and future cruises for this project will help inform multiple management issues concerning this region. The goal of this expedition was to validate several seep targets, image and map seeps, canyons (e.g., Keller, Pamlico, Hatteras, and unnamed canyons), and hard bottom features located between Virginia and Georgia.
