项目摘要

This research will be conducted under the auspices of the Coastal Ocean Processes (CoOP) program and is a continuation of a previously funded research project. Funding is provided for an integrated, interdisciplinary analysis and synthesis of extensive physical and biological samples and data collected off Duck, North Carolina in 1994 during the CoOP project, entitled "Suspension, cross-shelf transport, and deposition of planktonic larvae of inner-shelf benthic invertebrates." The field program provided simultaneous and comprehensive sampling of physical and biological patterns that comprise a unique resource from which investigators will derive a greater understanding of processes (both physical and behavioral) influencing the distribution and transport of invertebrate larvae over the inner continental shelf, as well as detailed knowledge of physical processes on the inner shelf. Sample analysis and data integration will continue on this unique data set in order to achieve the basic scientific objectives of the originally proposed research: (1) Do larval distributions show water mass or interface (i.e., fronts or clines) affinity? (2) Are there large changes in larval distributions during wind-driven, cross-shelf circulation (i.e., upwelling and downwelling)? (3) Does the freshwater plume from the Chesapeake Bay influence larval distributions on the inner shelf, both in terms of species composition (i.e., as a source of estuarine larvae) and of inner-shelf circulation? (4) Is there a semi-diurnal (i.e., tidal) variation in near-bottom larval concentrations? (5) Is there a correlation between near-bottom larval distributions and turbidity profiles? Do near-bottom larval distributions change during resuspension events and how might these changes affect larval transport? The work will be accomplished by six different teams of investigators at five separate institutions as a collaborative interdisciplinary effort.
这项研究将在海岸海洋过程(COOP)方案的主持下进行,是先前资助的研究项目的继续。资金用于对1994年在北卡罗来纳州达克收集的大量物理和生物样本和数据进行综合、跨学科的分析和综合,该项目题为“内陆架底栖无脊椎动物浮游幼虫的悬浮、跨架运输和沉积”。实地方案提供了物理和生物模式的同步和全面采样,这是一个独特的资源,调查人员将从中更好地了解影响内大陆架上无脊椎动物幼虫分布和运输的过程(物理和行为),以及关于内大陆架上的物理过程的详细知识。为了实现最初提出的研究的基本科学目标,将继续对这一独特的数据集进行样本分析和数据整合:(1)幼虫的分布是否显示出水团或界面(即,锋面或斜坡)的亲和力?(2)在风力驱动的跨陆架环流(即,上升流和下流)期间,幼虫的分布是否有很大的变化?(3)切萨皮克湾的淡水羽流是否影响内陆架上的幼虫分布,无论是从物种组成(即,作为河口幼虫的来源)和内陆架循环?(4)近底幼虫浓度是否存在半日(即潮汐)变化?(5)近底幼虫分布与浊度剖面之间是否存在相关性?在再悬浮事件期间,近底部幼虫的分布是否会发生变化?这些变化会如何影响幼虫的运输?这项工作将由五个不同机构的六个不同的调查小组完成,作为一项跨学科的协作努力。
