Aagaard/Swift The interannual variability of water properties in the Arctic Ocean will be investigated with a carefully defined statistical reduction of the data set used to prepare the multi-year gridded fields recently released under the Gore- Chernomyrdin environmental bilateral agreement. The statistical work will be conducted in collaboration with Russian colleagues at the Arctic and Antarctic Research Institute in St Petersburg. The purpose of the work is: (1) to carefully examine the Arctic Ocean temperature field from the various basins on a year-to-year basin; (2) to relate the fluctuations to changes in atmospheric forcing in the source regions; and (3) to test the hypothesis that the Arctic Ocean fluctuations are correlated with the North Atlantic Oscillation.

Aagaard/Swift将对北冰洋水性质的年际变化进行调查，并对最近根据戈尔-切尔诺梅尔金环境双边协定发布的多年网格化领域的数据集进行仔细定义的统计缩减。统计工作将与位于圣彼得堡的北极和南极研究所的俄罗斯同事合作进行。这项工作的目的是：（1）仔细检查北冰洋各海盆逐年的温度场;（2）将波动与源区大气强迫的变化联系起来;（3）检验北冰洋波动与北大西洋涛动相关的假设。
