Suspension, Cross-Shelf Transport and Deposition of Planktonic Larvae of Inner-Shelf Benthic Invertebrates

在许多沿海物种中，一个关键的柏拉图式幼虫阶段是在内陆大陆架的水域中度过的，这是大陆架最靠近海岸的几公里，深度通常小于30米。我们对这些浮游生物幼虫生活的大陆架的参数知之甚少。对强烈影响生物的物理过程，如沉积物运输和内陆架水的分层和循环，了解甚少。本研究的一个主要目标是在同一时间和空间尺度上获得生物、物理和沉积物输运参数的天气性、系泊性、长期测量。实地项目旨在深入了解可能控制生活在近岸沙质沉积物中的生物的浮游幼虫成功扩散和定居的过程。这项研究旨在解决关键的学科问题，以及跨学科的问题。指导这项研究的基本假设是，生活在潮间带（或非常浅的水域）的生物的浮游幼虫利用内大陆架的循环来控制它们的跨大陆架运输。

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.
