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.

This dataset contains water temperature, salinity, marine chemistry, and other data collected by SBE 911 plus conductivity-temperature-depth (CTD) and Niskin bottles from R/V Mirai, cruise MR20-05C, in the Arctic Ocean, Bering Sea, and North Pacific Ocean. Data units are specified in corresponding "Format_Information.txt" files. This dataset is U.S. State Department MSR RATS U2020-004. Data are in csv, xls, text, and image formats. Reports are in PDF.

This dataset contains water temperature, salinity, and others sea and atmospheric parameters taken by CTD and other instrumentation from the training ship Oshoro Maru in the Chukchi Sea, Bering Sea, and North Pacific Ocean. This cruise aims to understand hydrographic and ecosystem changes taking place in the northern Bering and Chukchi Seas. We conducted hydrographic, biogeochemical and ecosystem surveys, including plankton, microplastic, and fish samplings, from the northern Bering Sea to the Chukchi Sea. Data are in text, csv, png (picture) and mp4 (video). Data description is in PDF. This cruise is U.S. State Department MSR RATS U2022-051 as part of the World Data Service for Geophysics.

This dataset contains measurements conducted as part of meteorological and hydrographic surveys including marine biogeochemical samplings in the northern Bering Sea and Arctic Ocean on board the R/V Mirai, cruise MR16-06, from 22 August to 5 October 2016 under the Arctic Challenge for Sustainability (ArCS) Project. This dataset is U.S. State Department MSR U2016-011 as part of the World Data Service for Oceanography and Geophysics. Cruise data are available from the JAMSTEC DARWIN portal (see the Documentation).

This dataset contains currents, water temperature, salinity, and other variables taken by ADCP, TSG, and other instrumentation from the research vessel Mirai in the Bering, Chukchi, and Beaufort Seas. In 2022, the R/V Mirai conducted hydrographic surveys in the Bering, Chukchi and Beaufort Seas. This dataset includes preliminary data from the R/V Mirai 2022 Arctic cruise. Data and readme files were contained in the same directory. Some data or samples are still being processed and analyzed and will be submitted no later than two years after the cruise end. This cruise is U.S. State Department MSR U2022-002 as part of the World Data Service for Oceanography. Data are in various text formats.

This dataset includes surface underway, chemical, meteorological and physical data collected from R/V Mirai cruise MR20-05C (EXPOCODE 49NZ20201003) in the North Pacific Ocean, Bering Sea, Chukchi Sea, Arctic Ocean from 2020-10-03 to 2020-10-25. These data include water temperature, barometric pressure, partial pressure (or fugacity) of carbon dioxide - atmosphere, partial pressure (or fugacity) of carbon dioxide - water.
