摘要作为海洋俯冲观测研究的一部分，SeaSoar调查是在1991年春季和1992年秋季和1993年春季部署期间，在浮标浮标标记的俯冲水之后进行的。在后两种情况下，实时跟踪的限制使得很难准确定位浮子，因此重点是在最初部署在浅水近表层的几个浮子上的SeaSoaring。在实验过程中，共进行了13次调查。它们的设计是为了绘制中尺度（气象意义上的）或次中尺度（海洋学中通常使用的术语）的地图。此外，还借此机会获取了与浮标放在一起的其他水文数据，以填补上述时间取样的空白。在北大西洋副热带环流东北部局部发现的密度模式是马德拉模式水，其潜在密度接近26.5。结果表明，以下…
Abstract As part of an observational study of ocean subduction, SeaSoar surveys were carried out following subducting water tagged by bobber floats during their deployment in the spring of 1991 and again in the fall of 1992 and spring of 1993. In the latter two cases, real-time tracking limitations made it difficult to accurately locate bobbers, so the focus was on SeaSoaring over a few of the floats that were deployed in the shallow, near-surface layer initially. A total of 13 surveys were made over the course of the experiment. They were designed to map the mesoscale (in the meteorological sense) or submesoscale, as the term is generally used in oceanography. In addition, opportunity was taken to acquire other hydrographic data collocated with the floats in order to fill in the gaps in the above temporal sampling. The density mode locally found in the northeastern part of the North Atlantic subtropical gyre is Madeira mode water, with a mode near a potential density of 26.5. Results indicate that follow...
