WATER TEMPERATURE, SALINITY, and others taken by CTD and other instruments from the R/V Mirai (cruise MR25-05C) in the Chukchi Sea, Bering Sea, and North Pacific Ocean from 2025-08-31 to 2025-09-28 (NCEI Accession 0314366)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 03, 2026 at 05:23 AM | Dataset Last Updated: April 27, 2026 at 12:00 AM
This dataset contains ocean and atmosphere parameters taken from the R/V Mirai in the Chukchi Sea, Bering Sea, and North Pacific Ocean. This cruise aims to develop the dataset that could allow for a synoptic view of the totality of hydrographic and ecosystem changes taking place in the Arctic Ocean and facilitate advancing model development to predict the future state of the Arctic. We conducted hydrographic and biogeochemical surveys, including plankton, microplastic, and bottom sediment samplings, from the northern Bering Sea to the marginal ice zones of the Chukchi Sea. This dataset is U.S. State Department MSR RATS U2025-005.
