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 contains water temperature, salinity, and others taken by CTD and other instrumentation from the research vessel Mirai in the Chukchi Sea, Bering Sea, and North Pacific. 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 U2023-005 as part of the World Data Center for geophysics and oceanography. Data are in text formats.

An international Coupled Ocean-Atmosphere Response Experiment (COARE) was conducted in the warm-pool region of the western equatorial Pacific Ocean over a four-month period from November 1992 through February 1993 (Webster and Lukas, 1992). Most of the oceanographic and meteorological observations were concentrated in the Intensive Flux Array (IFA) centered at 1 degree, 45'S, 156 degree East. As part of this experiment, R/V Wecoma conducted three survey cruises. Each cruise included measurements of the temperature, salinity and velocity distribution in the upper 300m of the ocean, and continuous meteorological measurements of wind, air temperature, humidity, etc. Most of these measurements were along a butterfly pattern that was sampled repeatedly during the three COARE Surveys cruises, W9211A and W9211B, and W9211C.

The Conductivity, Temperature and Depth (CTD) and other data were collected in NW Pacific (limit-180), NE Pacific (limit-180), Greenland Sea and Bering Sea as part of Fisheries-Oceanography Coordinated Investigations (FOCI). Data was collected from NOAA Ship MILLER FREEMAN. The data was collected over a period spanning from April 4, 1992 to September 25, 1992. Data from 197 casts was submitted in one tape by Ms. Leslie Lawrence. Data has been processed and is available in F022-CTD-Hi Resolution file format of NODC. F022 High-resolution CTD data is collected from high resolution (conductivity-temperature-depth) instruments. As they are lowered and raised in the oceans, these electronic devices provide nearly continuous profiles of temperature, salinity and other parameters. Data values may be subject to averaging or filtering or obtained by interpolation and may be reported at depth intervals as fine as 1 m. Cruise and instrument information, position, date, time and sampling interval are reported for each station. Environmental data at the time of the cast (meteorological and sea surface conditions) may also be reported. The data record comprises values of temperature, salinity or conductivity, density (computed sigma-t) and possibly dissolved oxygen or transmissivity at specified depth or pressure levels. Data may be reported at either equally or unequally spaced depth or pressure intervals.

The ChukSA climatology is comprised of shipboard acoustic Doppler current profiler (SADCP) ocean velocity datasets collected by research vessels while working in, or transiting through, the Chukchi Sea region. SADCP datasets included in the climatology have received high- level post-processing, including manual editing and removal of estimated barotropic tides, and have been combined into a unique dataset of direct ocean velocity measurements. As of early 2023, ChukSA includes 95 datasets from 57 cruises by six ships spanning 16 years since 2002. To create the ChukSA climatology, the creators searched for SADCP datasets with cruise tracks that fell within the specified region of 65°-75° N and 170°-150° W. This was done by contacting colleagues and researchers who regularly work in the Chukchi region and by reaching out to the UNOLS Rolling Deck Repository (R2R) team, which archives cruise metadata and data from research vessels, to collect SADCP datasets from research missions as well as transits. Please see below for the original dataset citations and acknowledgements. The original datasets identified were retrieved in a variety of formats (from varying SADCP systems/manufacturers), with a wide range of post-processing completed. Frank Bahr (Woods Hole Oceanographic Institution) reviewed each dataset identified and assessed the need for post-processing. When necessary, appropriate post-processing methods were applied to datasets to ensure that all entries in the climatology were appropriate for climatological analysis. Post-processing methods are summarized in 'ChukSA_readme_final.pdf', with extensive details for each dataset available in a separate document titled ‘ChukSA_Appendix_A.pdf’. Final velocity measurements included in ChukSA are high quality and ready for use by the community. Data are in NetCDF.

This is an archive of CTD data (water temperature, salinity, dissolved oxygen, and others) from the 2019 Bering Strait mooring cruise. The cruise was funded by the NSF-Arctic Observing Network grant: - PLR-1758565 (PIs: Woodgate and Peralta-Ferriz). The data are from a ~ 10 day cruise - on the US research vessel Norseman II - from 5th-15th September 2019 - sailing from and to Nome, Alaska, USA - to the Bering Strait and southern Chukchi Sea. The cruise was also to service oceanographic moorings in the strait and those data are archived separately. A total of 438 casts were taken and are included in this archive. No water samples were taken during this cruise. Stations were taken in US waters near mooring locations and on sections in the Bering Strait and southern Chukchi Sea. See cruise report for map, station locations, calibration, and processing details. The data are taken using an SBE911p system, recording - pressure - temperature (dual system) - conductivity (dual system) - oxygen (dual system) - fluorescence - turbidity.
