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.

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 8th Chinese National Arctic Scientific Research Expedition (8th CHINARE) voyaged within the U. S. Exclusive Economic Zone from 20 to 25 September 2017, traversing the Bering and Chukchi Seas. The objectives of the 8th Chinese National Arctic Scientific Research Expedition were to improve understanding of basic environmental information of marine hydrology and sea ice variation in summer 2017 in areas of the Bering Sea, Chukchi Sea, Chukchi Sea Rise and Canadian Basin, and to provide basic information for global climate change research. Data sets of fundamental environmental parameters (temperature, salinity, depth, nutrients and Chlorophyll a (Chl a), the abundance of bacterioplankton, and records of benthic macroinvertebrates and demersal fish were obtained within this zone. During the 8th CHINARE, 23 stations defining four sections were investigated. Altogether, 997 conductivity /temperature /depth measurements, 99 nutrient data sets, 99 dissolved organic carbon (DIC) measurements, 99 dissolved oxygen (DO) measurements, 100 Chl a measurements, 42 particulate organic carbon/particulate nitrogen (POC/PN) measurements, 84 bacterioplankton abundance measurements, as well as records of benthic macroinvertebrates and demersal fish were collected. In addition, one set of hydrological mooring systems were recovered, although only one set was redeployed. These data are part of the World Data Service for Oceanography and US State Department Marine Research U2017-023 Data are text, XLSX, HEX, binary formats. XLSX were converted to CSV.

This dataset contains water temperature, salinity, and other parameters taken by CTD during the 2018 Bering Strait mooring cruise. Data are in CNV format. The cruise was funded by the NSF-Arctic Observing Network grants: - PLR-1304052 (PIs: Woodgate, Heimbach and Nguyen), and - PLR-1758565 (PIs: Woodgate and Peralta-Ferriz). The data are from a ~ 10 day cruise on the US vessel Norseman II from 2018-08-10 to 2018-08-19 sailing from and to Nome, Alaska, USA to the Bering Strait and the Southern Chukchi Sea. The cruise was also to service oceanographic moorings in the strait and those data are archived separately. A total of 142 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, and turbidity.
