Description:

The Deep-Sea Symphony: Exploring the Musicians Seamounts expedition (EX-17-08), conducted by NOAA and partners, was a combined mapping and remotely operated vehicle (ROV) exploration 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. This two-part cruise, the last expedition in the CAPSTONE initiative, commenced on August 8, 2017, and concluded on September 30, 2017, focusing on these areas in and around the Musicians Seamounts and the Hawaiian Islands in order to increase the understanding of these deep-sea ecosystems in this region to support management decisions. The expedition used the ship’s deepwater mapping systems to map over 85,000 km2 of seafloor, including more than 50 seamounts and ridges. In addition, 22 ROV dives were conducted with over 360 hours dedicated to seafloor and midwater communities at depths 290 m to 3,854 m. Hundreds of animals were observed (many of which could be new species or records for the region), including 18 high-density coral and sponge communities, precious corals, and midwater species. In total, 178 samples (36 geological samples, and 142 biological samples) were collected for further analysis. Additionally, sonar anomalies were investigated as part of NOAA’s Underwater Cultural Heritage (UCH) work. This report summarizes operations conducted during EX-17-08, presents data collected, and provides an overview of the initial findings.
