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.

Bering Strait Mooring Cruise Underway Data 2022 This is an archive of underway data from the Bering Strait mooring cruise on the research vessel Norseman II, from Nome to Nome, 8th-19th September 2022. The cruise collected 3 types of underway data: meteorological (including wind velocity, air temperature and pressure and relative humidity); thermosalinograph (temperature and conductivity); and vessel-mounted ADCP (with bottom tracking). For full parameter list, see data file headers. To avoid sediment clogging of the thermosalinograph, that system was turned off while the ship was in Port Clarence during a large storm (~16-18 September 2022).

This data set contains physical oceanographic data from acoustic Doppler current profilers (ADCP) and conductivity-temperature-depth (CTD) sensors on moorings in the Bering Strait for a year beginning July 2016. There were a total of three moorings. Two moorings (A2 and A4) are in the US zone of the strait and one mooring (A3) is at a site just north of the strait. Mooring deployments were funded by the NSF-Arctic Observing Network award PLR-1304052. Data files are in text format.

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).

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.

A comparison between met data from the previous system and ERA, JRA and NCEP data, suggested that the 2021 data from the new system were too high (~2m/s) for wind speed, too low (~2degC)for temperature, and too low (~2hPa) for air pressure. That was based on a calibration done under less than ideal conditions. The system was recalibrated before the 2022 cruise, in the anticipation that would improve the data, however it has not yet been possible to make the same comparison to the ERA, JRA, and NCEP data to see if this has indeed fixed the issue. = thermosalinograph - raw Julian Day from Seasave system subject to GPS Roll over error. This is corrected in the data archived. - seachest was erroneously isolated from seawater intake at start of cruise. This was corrected 6th July 0615 GMT. Seachest data before this time are not measuring in situ water, and thus values have been set to a dummy value of 9999. This problem did not affect intake temperature. - raw depth data were frequently noisy. Flyers over 62m have been linearly interpolated from neighboring points 11) Other related data sets: = these data were taken on a mooring deployment cruise, which placed 3 moorings (A2-23, A3-23, A4-23) in the Bering Strait region. These moorings are part of a long-term time-series started in 1990 = prior mooring cruises to the region have collected underway data.

This dataset contains ocean currents, bathymetry, and others collected by ADCP, echo sounder, and other instrumentation from the research vessel Mirai in the Western Pacific Ocean. MR21-Ueki cruise is a part of study for short-term climate variability such as El Niño/Southern Oscillation (ENSO), Asia-Australia monsoon, Madden-Julian Oscillation (MJO), Boreal Summer Intra-Seasonal Oscillation and so on, and the improvement of the prediction skills for those phenomena. For that purpose, we conducted observations for variability of upper ocean and air-sea fluxes by a research vessel and moorings. The moorings also contribute to the internationally-coordinated Tropical Pacific Observing System (TPOS) for ENSO monitoring, and operational weather and seasonal prediction by the operational meteorological agencies in the world. We conducted mooring operations at 4 sites and comprehensive air-sea observation, which includes observations by the R/V MIRAI, wave gliders, surface drifters, profiling floats and moorings at around 13˚N 137˚E.
