| Abstract: | During the
second Chinese Arctic Scientific Expedition (CHINARE 2003. 2003.07 ~ 2003.09),
chlorofluorocarbons (CFCs) were measured from water samples collected from 26
stations in the Chukchi
Sea and adjacent areas. CFCs
data indicated that they had not reach saturation in surface waters. The 170°W
section distribution of CFCs and the thermohaline characteristics in the Chukchi Sea
confirmed that there was an inflow of Pacific Ocean water into the Arctic Ocean via the Central Channel. There are three
main new results. The first, there were two sources of freshwater, the Alaskan
Coastal Water (ACW) and sea ice melt water, in the shallower than 20 m
seawater. The second, the water mass at station BS09A was ACW, and that
stations BS06A and BS07A were likely to be a place of confluence for ACW and Bering Sea shelf Water (BSW), or for ACW, BSW and Anadyr
Water (AW) water masses. The third, the ACW almost flowed along the coast, and
so it had less influence on the more distant offshore stations. |
