Description (provided by applicant): The role of the Shellfish Kinetics Research Project component of this Center proposal is to: develop a predictive understanding of the physical, ecological and organismal processes that regulate the opportunity for benthic bivalves to accumulate and bind domoic acid as a result of filter feeding Pseudo-nitzschia spp. and other microscopic algae bearing marine toxins. The overall objective is to integrate the oceanography and domoic acid on the Pacific Coast and oceanography and domoic acid in Puget Sound investigations with the human health and risk assessment components of the Center (see Human Exposure Research Project and the Informatics Facility Core). The investigators will directly interface with the oceanography and domoic acid in Puget Sound component through the comparison of acute domoic acid toxicity along the coast (where domoic acid is an acute problem) to the Puget Sound (where there are only chronic low-level exposures, with essentially no acute domoic acid toxicity). To achieve these goals the investigators have separated the Shellfish Kinetics Research Project into two projects. Project 1 will focus on comparisons between offshore/neritic and nearshore regions, with the specific goal of understanding the mechanisms underlying the flux of toxic algae from the water column into near shore benthic bivalves. The second project seeks to follow the consequence of bivalve assimilation of domoic acid.

描述（由申请人提供）：该中心提案的贝类动力学研究项目组成部分的作用是：发展对物理，生态和有机体过程的预测性理解，这些过程调节底栖双壳类动物积累和结合软骨藻酸的机会，这是滤食伪菱形藻的结果。以及其他含有海洋毒素的微小藻类。总体目标是将太平洋海岸的海洋学和软骨藻酸以及普吉特海湾的海洋学和软骨藻酸调查与该中心的人类健康和风险评估组成部分结合起来（见人类接触研究项目和信息学设施核心）。调查人员将通过比较沿着（软骨藻酸是一个严重问题）与普吉湾（只有慢性低水平暴露， 基本上没有急性软骨藻酸毒性）。为了实现这些目标，研究人员将贝类动力学研究项目分为两个项目。 项目1将侧重于近海/浅海和近海岸区域之间的比较，具体目标是了解有毒藻类从水柱流入近海岸底栖双壳类的机制。第二个项目旨在跟踪软骨藻酸的双壳类同化的结果。
