The Conductivity, Temperature and Depth (CTD) and other data were collected in Bering Sea and Chukchi Sea. Data was collected from Ship ALPHA HELIX. The data was collected over a period spanning from September 9, 1993 to October 10, 1993. Data was submitted in a diskette by Dr. Chirk Chu, Institute of Marine Science, University of Alaska, Fairbanks, AK. 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.

This dataset contains water temperature, salinity, phytoplankton, zooplankton, and suspended particulate matter taken by CTD, nets, and other instrumentation in the Bering and Chukchi Seas from the research vessel icebreaker Xue Long during the 5-th Chinese National Arctic Scientific Research Expedition (CHINARE5). The objectives of the CHINARE5 were to improve understanding of basic environmental information of marine hydrology in summer 2012 in areas of the Bering Sea, Chukchi Sea, Chukchi Sea Rise, and to provide basic information for global climate change research. The main work was undertaken through sectional observations of the aforementioned sea areas. Data are in CNV, XLSX formats. This dataset is U.S. State Department MSR U2012-020 as part of the World Data Services for Geophysics and Oceanography.

This dataset contains water temperature, salinity, currents, marine chemistry, biology, geology, and underway meteorology taken by CTD, LADCP, and other instruments in the Bering and Chukchi Sea from the research vessel Xuelong from 2018-09-04 to 2018-09-09. Data were collected during the CHINARE 2018 Arctic expedition, including work performed in the US EEZ. Data are in text, xls, csv formats. Data report is in pdf. CTD data are in the SeaBird HEX format, processed data are in CNV. ADCP data are in the Teledyne RD Instruments binary format (*.0000), processed data are in NetCDF. This dataset is U.S. State Department MSR U2018-018 as part of the World Data Services for Geophysics and Oceanography.

This dataset contains ocean temperature and salinity profiles from CTD and bottle samples collected aboard the USCGC Healy and R/V Sikuliaq during cruises HLY1301 and SKQ201505s, respectively, in the Bering Sea and Chukchi Sea between 2013-08-03 and 2015-04-03. These data were collected by Christopher R. Paver (NCEI) and Dr. Louis A. Codispoti (UMCES) conducting research on bottle flushing protocol. These data were submitted by Christopher R. Paver.

The University of Alaska, Institute of Marine Science is responsible for this data collected aboard the R/V Alpha Helix on cruise number HX90 between 2022 17-Sep-1986 to 25-Sep-1986 by Dr. R. Tripp of the Department of Oceanography, University of Washington. There was a total of 43 stations in the Bering and Chukchi Sea area. The station numbers are: 1-43. Data has been processed to the NODC standard High-Resolution STD/CTD Data (F022) format. The F022 format contains high-resolution data collected using CTD (conductivity-temperature-depth) and STD (salinity-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 1m. 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. A text record is available for comments.

This is an archive of data from moorings deployed in Bering Strait from summer 2019 and summer 2020 to summer 2021. Mooring deployments were funded by the NSF-Arctic Observing Network award PLR-1758565 (PIs: Woodgate and Peralta-Ferriz). The mooring work required 3 dedicated cruises: - in 2019 (5th - 15th September), a ~ 11 day cruise on the US vessel Norseman2 deployed the 2019 moorings. Some CTD sections were run on this cruise, and those data are archived separately. - in 2020 (1st - 18th September), a ~ 19 day cruise on the US vessel Norseman2 deployed the 2020 moorings. Some CTD sections were run on this cruise, and those data are archived separately. - in 2021 (7th - 17th July), a ~ 11 day cruise on the US vessel Norseman2 recovered all the moorings. Some CTD sections were run on this cruise, and those data are archived separately. In both 2019 and 2020, a total of three moorings were deployed (each year): - two moorings (A2 and A4) in the US channel of the strait, - one mooring (A3) at a site just north of the strait. In what follows, mooring names include a two digit suffix to represent year of deployment. Although the 2019 moorings would normally have been recovered in 2020, the global COVID-19 pandemic prevented this. Instead, the 2020 cruise only deployed a further 3 new moorings (each ~ 400m west of their usual positions). All 6 moorings were recovered in 2021. Sites A2, and A3 were established in 1990. A2 and A3 have been occupied almost continuously (all years except 96-97) since then. Site A4 was established in 2001. Mooring location A2 is in the middle of the eastern (Alaskan side) channel. Mooring location A3 is just north of the strait, immediately east of the Russian-US EEZ (Exclusive Economic Zone) line. Experience has shown that site A3 samples both eastern and western channel water. Mooring location A4 is close to the Alaskan coast and allows measurement of the Alaskan Coastal Current.

Bathymetric contours were generated from soundings collected by National Ocean Service vessels from ~1900 to ~1971. The 1:250,000 maps are available for U.S. coastal waters. Bathymetric contours are in meters, with 10 meter intervals out to 200 m, supplemented by 2 m contours. Beyond 200 m, contours are at 50 m intervals to maximum depth. The GIS database derived from these maps includes the Bering, Chukchi, and Beaufort Seas in western and northern Alaska (~100 maps).

This dataset includes the profile discrete measurements of dissolved inorganic carbon, total alkalinity, CTD salinity and temperature collected in the summer of 2012 aboard R/V Xuelong in the Chinese Arctic Research Expedition (CHINARE12) cruise. The CHINARE project is an international collaboration between U.S. and Chinese scientists to study the water column carbonate chemistry in the western Arctic Ocean and Bering Sea.

This dataset includes surface underway, chemical, meteorological and physical data collected from R/V Mirai cruise MR21-05C (EXPOCODE 49NZ20210901) in the North Pacific Ocean, Bering Sea, Chukchi Sea, Arctic Ocean from 2021-09-01 to 2021-10-11. These data include water temperature, barometric pressure, partial pressure (or fugacity) of carbon dioxide - atmosphere, partial pressure (or fugacity) of carbon dioxide - water.
