摘要：作为美国国家科学基金会极地项目办公室发起的淡水倡议的一部分，来自华盛顿大学应用物理实验室和贝德福德海洋研究所的一组科学家正在调查戴维斯海峡的淡水交换。这条300公里宽的海峡位于巴芬岛和格陵兰岛西海岸之间，是加拿大北极群岛和亚极地北大西洋之间水域的门户。2004年秋季，R/V Knorr巡航179-05进行了三次为期一年的系泊部署中的第一次。6个地下系泊、1个离轴声源、8个底部着陆器和2个滑翔机成功部署在戴维斯海峡稍微偏北的海域。四条两岸水文线，完成了化学示踪剂的采样，表征了从巴芬湾南端到拉布拉多海北端的水质量变化。系泊阵列将在至少三年的时间内每年进行恢复、维修和重新部署。
Abstract : As part of the Freshwater Initiative sponsored by the National Science Foundation Office of Polar Programs, a team of scientists from the Applied Physics Laboratory of the university of Washington and the Bedford Institute of Oceanography are investigating freshwater exchange through Davis Strait. This 300-km-wide strait sits between Baffin Island and the west coast of Greenland and acts as the gateway for waters passing between the Canadian Arctic Archipelago and the subpolar North Atlantic. In autumn 2004 R/V Knorr cruise 179-05 undertook the first of three one-year mooring deployments. Six subsurface moorings, one off-axis sound source, eight bottom landers, and two Seagliders were deployed successfully slightly north of the Davis Strait sill. Four cross-strait hydrographic lines, complete with sampling for chemical tracers, characterized water mass variability from the southern end of Baffin Bay to the northern tip of the Labrador Sea. The moored array will be recovered, serviced, and redeployed annually for a period of at least three years.
