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.
