The First Chinese Arctic Expedition to the Arctic Ocean was carried out from July 1 to September 8,1999,aboard the icebreaker R/V Xuelong supported by two helicopters and a boat, organized by the Chinese Arctic and Antarctic Administration, State Oceanic Administration. Twenty five scientists in the scientific disciplines of physical oceanography, marine chemistry, marine biology, biogeochemistry, marine geology, glaciology, atmospheric science and fisheries from ten research institutions and universities in China, as well as scientists from the National Institute of Polar Research, Japan and the Korean Ocean Research and Development Institute, took part in the field investigations and cooperative research. The working areas covered the Canadian Basin, Chukchi Sea in the Pacific sector of the Arctic Ocean, and the Bering Sea. The following data and samples were obtained during that expedition. For oceanography, operations of more than 100 CTD deep stations and 70 XBT and XCTD probes (to the depth of 1000m) were completed, and 1423.6Mb model VM ADCP (Acoustic Doppler Current Profiler) data were obtained. For geology, sediment samples by box sampler and multi-tube sampler in 41 locations and 47.92m of column sediment samples in 17 locations were collected. Vertical and horizontal trawls in 110 locations were made for biology and ecology, and EK-500 and 792DSG fish-finder in over 5800 nautical miles and 19 trawls were operated. A variety of samples of sea water, air and snow and sea ice cores etc. for research on chemistry, isotopes, primary productivity, microbiology, phytoplankton, nanoplankton, aerosols and samples from sediment traps were obtained at two stations on ice floes. Boundary and upper-air observations including ozone and ice-radar measurements of ice thickness were also made. The northernmost station was at 77°N in the Canadaian Basin. All samples and data are now being analyzed and results of scientific research have been published. Cooperative research on our data and samples obtained by the ...
