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.

基于载人潜水器（human occupied vehicles）Shinkai6500对海底的详细观测，我们研究了蛇纹岩驱动流体流动、微生物与大型动物群落的分布及其与海底地形的关系，获取了各类岩石、沉积物、矿床、水体及动物样本。大部分数据与样本目前仍在陆上实验室中开展分析研究。这些数据通过Shinkai6500搭载的CTD所获取的航行中测量数据及XBT剖面数据得到补充。本次航次为美国国务院MSR U2022-052航次，是世界地球物理与海洋学数据服务（World Data Service for Geophysics and Oceanography）的组成部分。数据格式包括文本格式及仪器专用格式。
