Seafloor topography, animals - individual, water temperature, and other underway data taken by CTD, echo sounder, and other instruments from the deep submersible research vehicle Shinkai6500 deployed from the research vessel Yokosuka in Marianas Trench Marine National Monument from 2023-07-25 to 2023-08-04 (NCEI Accession 0289670)

Based on the detail seafloor observation by human occupied vehicles (Shinkai6500), we observed the distribution of serpentinite-driven fluid flows and microbial and macrofaunal communities with the seafloor topography, obtained various types of rocks, sediments, deposits and waters, and animals. Most of the data and samples are still under investigation in onshore laboratories. These data are augmented by underway measurements taken by CTD installed on the Shinkai6500 and XBT profile data. This cruise is U.S. State Department MSR U2022-052 as part of the World Data Service for Geophysics and Oceanography. Data are in text and instrument-specific formats.
