（约26.0公斤立方米）全年相当稳定。但剥离层的垂直尺度随季节变化较大，冬、春季可达6080 m，夏季仅达2040 m。垂直尺度受季节性密度跃层的强度和深度控制。观测结果表明，在冬季和春季，分离层能够延伸到透光层。索引术语：4528海洋学身体状况：前缘和喷流4211海洋学概述：海底边界层; 4219海洋学：概述：大陆架进程; 4279海洋学概述：上升流和汇聚;关键词：底边界层，陆架前缘，中大西洋湾
(approximately 26.0 kg m 3 ) is fairly constant throughout the year. However, the vertical scale of the detached layer varies significantly with season, extending 6080 m above the bottom in winter and spring, but only 2040 m above the bottom in summer. The vertical scale is controlled by the strength and depth of the seasonal pycnocline. The observations suggest that the detached layer is capable of extending into the euphotic zone during winter and spring.
