Using SEEP II water column data and sedimentary trap samples, the PI's will address specific questions regarding planktonic production, mortality and downslope transport in the Slope environment. These trap samples were collected before, during and after major mesoscale hydrographic events such ad outbreaks of costal water and intrusion of warm-core rings. The working hypothesis is that much of the material that collects on the slope is advected there from shelf water.

使用 SEEP II 水柱数据和沉积圈闭样本，PI 将解决有关斜坡环境中浮游生物产生、死亡率和下坡迁移的具体问题。 这些陷阱样本是在重大中尺度水文学事件（例如沿海水域爆发和暖核环入侵）之前、期间和之后收集的。 工作假设是，斜坡上收集的大部分物质是从陆架水平流输送到那里的。
