The reporter learned from China's 16th Arctic Ocean Expedition that during the recent annual survey in the Canadian basin of the Arctic Ocean, the research team discovered that the temperature of the subsurface water at a depth of 50 meters to 100 meters in the region this year was significantly higher than in the same period in the past. Chen Hongxia, captain of the “Xuelong 2” marine team, said that this voyage continued the annual observation section of 169 degrees west longitude. Vertical cross-sectional observations of ocean water spanning 6 to 7 latitudes were carried out through temperature and salt depth instruments. The observation results provided a basis for evaluating the interannual changes in Pacific water flowing into the Arctic Ocean. According to data collected from China's 9th to 15th Arctic Ocean expeditions, the temperature of the subsurface water at depths of 50 meters to 100 meters in the region was between minus 1.75 degrees and minus 1.15 degrees, but the data obtained during this survey rose significantly to between minus 0.5 degrees and 0 degrees.
