In many coastal species, a critical platonic larval stage is spent in the waters of the inner continental shelf, the most shoreward few kilometers of the shelf where depths are typically less than 30 m. Our knowledge of the parameters of the shelf where these planktonic larvae live is meager. Physical processes which strongly influence the biology, such as sediment transport and the stratification and circulation of inner shelf waters, are poorly understood. A major goal of this study is to obtain synoptic, moored, long-term measurements of biological, physical and sediment transport parameters at the same time and space scales. The field program is aimed at gaining insight into the processes that may control the successful dispersal and settlement of planktonic larvae of organisms living in near-shore sandy sediments. The study is designed so that critical disciplinary, as well as interdisciplinary questions can be addressed. The basic hypothesis guiding the research is that planktonic larvae of organisms living in the intertidal zone (or in very shallow water) exploit the circulation of the inner shelf to control their cross-shelf transport.

在许多沿海物种中，关键的柏拉图幼虫阶段花在了内部大陆架的水域，这是架子上最高的几公里，那里的深度通常小于30 m。 我们对这些浮游幼虫活的架子参数的了解很少。 强烈影响生物学的物理过程，例如沉积物的运输以及内架水的分层和循环，对生物学的分层和循环尚不清楚。 这项研究的主要目的是获得同时和空间尺度的生物，物理和沉积物传输参数的天气，系泊，长期测量。 该野外计划旨在洞悉可能控制居住在近岸沙质沉积物中的生物体的浮游生物幼虫的成功分散和沉降。 该研究的设计是为了解决关键的学科以及跨学科问题。 指导研究的基本假设是，生活在潮间带（或非常浅水）的生物体的浮游幼虫利用了内架子的循环以控制其交叉架子的运输。
