Dataset Overview | National Centers for Environmental Information (NCEI)

Water temperature, salinity, and other parameters collected from the research vessel Mirai in the Chukchi Sea, Bering Sea, and North Pacific Ocean from 2021-09-05 to 2021-10-10 (NCEI Accession 0251653)

Preview graphic

This dataset contains water temperature, salinity, and others sea and atmospheric parameters taken by CTD and other instrumentation from the research vessel 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 Canada Basin. This dataset is U.S. State Department MSR RATS U2021-007. Data are in text formats, IceRadar data are radar screenshots in image (JPG) format, data description and reports are in PDF.
