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.

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.

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, 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 includes biological, chemical, discrete sample, physical and profile data collected from NATHANIEL B. PALMER in the Arctic Ocean, Beaufort Sea and Bering Sea from 2003-07-05 to 2003-08-20 and retrieved during cruise CARINA_320620030705. These data include AMMONIUM, CHLOROPHYLL A, Chromophoric Dissolved Organic Matter (CDOM), DISSOLVED ORGANIC CARBON, DISSOLVED OXYGEN, FLUORESCENCE, HYDROSTATIC PRESSURE, NITRATE, NITRITE, PHAEOPHYTIN, PHOSPHATE, PHOTOSYNTHETIC ACTIVE RADIATION (PAR), Potential temperature (theta), SALINITY, SILICATE, UREA and WATER TEMPERATURE. The instruments used to collect these data include CTD, PAR Sensor and bottle. These data were collected by Louis A. Codispoti of Horn Point Laboratory (UMCES HPL) and James H. Swift of Scripps Institution of Oceanography (SIO) as part of the CARINA/320620030705 dataset. The CARINA (CARbon dioxide IN the Atlantic Ocean) data synthesis project is an international collaborative effort of the EU IP CARBOOCEAN, and U.S. partners. It has produced a merged internally consistent dataset of open ocean subsurface measurements for biogeochemical investigations, in particular, studies involving the carbon system. The original focus area was the North Atlantic Ocean, but over time the geographic extent expanded and CARINA now includes data from the entire Atlantic, the Arctic Ocean, and the Southern Ocean.
