电导率-温度-深度数据从海洋哺乳动物探索海洋从极点到极点程序的仪表密封进行了分析,以表征水团和边缘海的季节性。底层温度被发现是在一个寒冷的制度,在密集的陆架水(DSW)生产区,确定在这项研究中作为南部威德尔海,达恩利角,Pradriz湾,阿德利海岸,和西部罗斯海。DSW全年占据威德尔海和罗斯海大陆架的底部:DSW的生产和垂直翻转只发生在冬季。在其他DSW生产区,盐度在夏季下降得更明显。我们确定的玛莎公主海岸,利奥波德和阿斯特丽德海岸,诺克斯海岸低盐度陆架水生产区,修改环极深水(CDW)侵入大陆架,达到接近冰架保持底部温度在中间制度的地区。哈拉尔王子海岸,阿蒙森海和别林斯高晋海经历更强烈的CDW入侵,使它们全年处于温暖状态。CDW层厚度与陆架海上空的纬向风和斜坡上的纬向风相关,而DSW层厚度与陆架海上空的纬向风和斜坡上的风应力旋度相关。DSW在大陆架上的位置与冰架附近没有温暖的CDW相吻合。
Conductivity‐temperature‐depth data from instrumented seals of the Marine Mammals Exploring Oceans from Pole to Pole program are analyzed to characterize the water masses and the seasonality of the marginal seas. Bottom temperatures are found to be in a cold regime in Dense Shelf Water (DSW) producing regions, identified in this study as the southern Weddell Sea, Cape Darnley, Prydz Bay, Adélie Coast, and the western Ross Sea. DSW occupies the bottom of the Weddell and Ross Sea continental shelves throughout the year: Production of DSW and vertical overturning occur only during the winter. In the other DSW producing regions, salinity is reduced more markedly during the summer. We identify the Princess Martha Coast, Leopold and Astrid Coast, and the Knox Coast as Low Salinity Shelf Water producing regions, where modified Circumpolar Deep Water (CDW) intrudes onto the continental shelf, reaching areas close to the ice shelves keeping the bottom temperatures in an intermediate regime. The Prince Harald Coast, the Amundsen Sea, and the Bellingshausen Sea experience more intense CDW intrusion, which keeps them in a warm regime year‐round. CDW layer thicknesses correlate with the meridional winds over the shelf sea, and with the zonal winds at the slope, while DSW layer thicknesses correlate with the meridional winds over the shelf seas and the curl of the wind stress over the slope. Locations of DSW on the continental shelf coincide with an absence of warmer CDW near the ice shelves.
