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.

This archive is of data from 150 CTD casts taken during the 2013 Norseman II cruise to the Bering Strait. For positions, see file headers or the cruise report accompanying these data. Data were preliminary processed at sea, as per cruise report, and bottle files were obtained from this processing. Subsequently, significant issues were found with the data as regards to lack of reliability of salinity and oxygen on the downcasts. A reprocessing attempts to address these issues. (Bottle data were not reprocessed.) This archive includes: 1) the raw data files (.hdr, .hex. and .XMLCON) for each cast, so the user may reprocess the data to their own standards, 2) 2db average UPCAST data for each cast, as per Oct 2015 data processing. As will be discussed below, these data provide (we believe) the most reliable salinity and oxygen data (although note no oxygen or salinity samples were taken for validation), 3) the 2db resolution reflects uncertainty in the depth of the data as the upcast data are being used, 4) casts with particularly suspect salinity data at times of sharp temperature gradients (Casts 83, 90,91,94,100,101,103) are placed in a subdirectory, and 5) the .ros and .btl bottle data as obtained from the processing at sea. We encourage those seeking parameters to match bottle samples to consider also the 2db averaged cast data. A summary of know problems include: 1) salinity values at times of sharp temperature gradient and 2) salinity and oxygen values on the downcasts.

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, nutrients, velocity, and others taken by CTD, ADCP and other instrumentation from research vessel icebreaker Xuelong in the North Pacific Ocean, Arctic Ocean, and Bering Sea from 2014-07-22 to 2014-08-04. The objectives of The 6th Chinese National Arctic Scientific Research Expedition were to improve understanding of basic environmental information of marine hydrology in high latitude areas. The China Arctic Expedition of 2014 (Chinare 2014) campaign was designed to provide basic information for global climate change research. The main work was undertaken through sectional observations of the above mentioned sea areas. During the 6th Chinese National Arctic Research Expedition, about 14 days (2014.7.22—2014.8.4) had been taken to investigate the marine physical, chemical oceanography and biological ecology, as well as marine geology. Different parameters had been observed, including 53 CTD sites, 53 LADCP sites, 12 Chlorophyll sites, 19 Zooplankton sites and 22 Nutrients sites. Besides, 16 sedimentary cores or surface sediments had been collected. These data are submitted as part of the World Data Service for Oceanography, Marine Research data U2014-022. Data are in text, XLS, and binary formats.

This dataset contains water temperature, salinity, and others taken by CTD, ADCP, and other instrumentation from research vessel icebreaker Xue Long in the North Pacific Ocean, Bering Sea, and Arctic Ocean. The 7th Chinese Arctic Research Expedition targets on the global climate change and the correlations of sea ice variation, as well as its effects on the environment and ecosystem in Arctic Ocean. The major studies are focused on physical oceanography, marine chemistry, marine geology and marine ecology. The objectives of the studies are: 1) Investigation of primary path of pacific waters and land-derived fresh waters input to Canada Basin; 2) Observation on marine chemical parameters in Arctic Ocean and the influences on cycling of biogeochemistry. 3) Identification of plankton species and bio-diversity in Arctic area. The cruise was carried out during 11 July to 26 September, 2016. The field work in the U.S. EEZ was a part of this cruise. During the field work in the U.S. EEZ, observations/measurements of physical oceanography, meteorology, marine chemistry, marine Biology and marine geology are occupied in the Bering Sea and the Chukchi Sea. These data are part of the World Data Service for Oceanography and U.S State Department Marine Research dataset U2016-024. Data are in XLSX, HEX, binary formats. XLSX were converted into CSV.
