R/V Conrad在西斯科舍海获得的FDRAKE-75数据分量揭示了从南极到亚南极水域经过时所遇到的温盐层化带序列。极锋区将200 m以上的南极区与100 m至400 m以上的亚南极区（近等盐层）分隔开，南极区以一次强烈的T-min为特征。威德尔海和斯科舍海的南极区被位于南斯科舍海的一个寒冷、相对均匀的区域分开，这个区域被称为威德尔-斯科舍汇合处。极锋带的边界是高度弯曲的，亚南极水的孤立漩涡可能出现在该区域内。南极绕极流的主轴显然位于极锋区的亚南极边界附近，而副轴则与极锋区的南部边界有关。视察奥卡达斯群岛和梅尔维岛…
Abstract The component of the FDRAKE-75 data obtained by the R/V Conrad in the western Scotia Sea reveals a definite sequence of thermohaline stratification zones encountered on passing from Antarctic to Sub-antarctic waters. A Polar Front Zone, displaying multiple temperature minima, separates the Antarctic Zone, characterized by a single intense T-min above 200 m, from the Subantarctic Zone with its nearly isohaline layer from 100 m to over 400 m. The Antarctic Zones of the Weddell and the Scotia Seas aye separated by a cold, relatively homogeneous zone situated in the southern Scotia Sea called the Weddell-Scotia Confluence. The boundaries of the Polar Front Zone are highly meandered and isolated eddies of Subantarctic water may occur within the zone. The main axis of the Antarctic Circumpolar Current apparently lies close to the Subantarctic boundary of the, Polar Front Zone, while a secondary axis is associated with the southern limit of the Polar Front Zone. Inspection of the Islas Orcadas and Melvi...
