Oceanographic observations from the Ice Station Weddell 1 show that the western rim of the Weddell Gyre contributes to Weddell Sea Bottom Water. A thin (< 300 meters), highly oxygenated benthic layer is composed of a low-salinity type of bottom water overlying a high-salinity component. This complex layering disappears near 66 degrees S because of vertical mixing and further inflow from the continental margin. The bottom water flowing out of the western rim is a blend of the two types. Additionally, the data show that a narrow band of warmer Weddell Deep Water hugged the continental margin as it flowed into the western rim, providing the continental margin with the salt required for bottom-water production.
威德尔海环流西部边缘对威德尔海底层水有贡献，这是威德尔海环流西部边缘对威德尔海底层水有贡献，这是威德尔海 1 号冰站的海洋观测结果。在西部边缘，存在一个厚度较薄（<300 米）、高含氧的底层水层，它由低盐度底层水和高盐度成分组成。在南纬 66 度附近，由于垂直混合和从大陆架进一步流入的影响，这种复杂的分层现象消失了。从西部边缘流出的底层水是这两种水的混合。此外，数据还表明，当较温暖的威德尔深海水流进入西部边缘时，它紧贴着大陆架流动，为底层水的产生提供了所需的盐分。
