    • Water temperature, bottom topography, currents, and others taken by XBT, echosounder, ADCP, and other instrumentation from research vessel Kaimei in Marianas Trench Marine National Monument from 2023-03-03 to 2023-03-25 (NCEI Accession 0283273)

    Metadata Updated: February 1, 2026

    This dataset contains water temperature, bottom topography, currents, marine gravity, and sub bottom profiles taken from R/V Kaimei in the North Pacific. Based on the detail seafloor observation by remotely operative vehicles (KM-ROV and BMS), we observed the distribution of deep-sea hydrothermal activities and microbial and macrofaunal communities with the seafloor topography, obtained various types of rocks, sediments, hydrothermal deposits and waters, and animals. Most of the data and samples are still under investigation in onshore laboratories, but some of the data and samples were analyzed onboard and then interpreted and summarized as scientific articles. This cruise is U.S. State Department MSR U2022-047 as part of the World Data Service for Geophysics. Data are in text and instrument specific formats.
