Description:

The 2016 Deepwater Exploration of the Marianas expedition (EX-16-05), conducted by NOAA and partners, was a combined mapping and remotely operated vehicle (ROV) expedition conducted as part of NOAA’s Campaign to Address Pacific monument Science and Technology NEeds (CAPSTONE), a multi-year foundational science effort to collect critical data and information in unknown and poorly-known deepwater areas in U.S. marine protected areas (MPAs) in the central and western Pacific Ocean. The final leg (EX16-05-L3) in this three-part expedition commenced on June 17, 2016, and continued through July 10, 2016, focusing on areas in and around the Marianas Trench Marine National Monument (MTMNM) and the Commonwealth of the Northern Mariana Islands (CNMI). The main objective of EX-16-05 Leg 3 was to focus primarily on the northern half of the Marianas region—where past research cruises identified hydrothermal vents, but did no investigation of bottomfish, deep-sea coral habitats, or a number of submarine volcanoes. Before this expedition, many of the flanks of islands in the Marinas Arc remained unexplored and unmapped within the Monument. The expedition used the ship’s deepwater mapping systems to map over 27,700 km2 of seafloor. In addition, 22 ROV dives were conducted with over 120 hours dedicated to seafloor and midwater communities at depths 250 m to 6,000 m. During these dives, over 300 different organisms were observed, many of which could be new species or records for the region, and several high-density coral and sponge communities were examined. In total, 113 samples (45 geological samples, and 68 biological samples) were collected for further analysis. This report summarizes operations conducted during EX-16-05 Leg 3, presents data collected, and provides an overview of initial findings.
