Individual Based Modeling of Particles and Pelagic Organisms in Chesapeake Bay

这是一个为期四年的教师早期职业发展（Career）奖，包括基础科学和课程开发两个部分。该研究将开发和应用切萨皮克湾的广义拉格朗日粒子轨迹模型，该模型随后将用于开发基于个体的、耦合的海荨麻生物和物理模型。这项研究将有两个主要目标：第一是为切萨皮克湾研究界提供一个一般的粒子轨迹模型，可以作为切萨皮克湾物理、化学和生物研究的工具。二是利用模型研究物理和生物过程之间的相互作用如何决定切萨皮克湾海蜇的时空分布及其对猎物的影响。三维的、随时间变化的流动将由一个流体动力学循环模型提供，该模型是作为切萨皮克湾项目的一部分开发的。来自NSF LMER-TIES野外观测项目的凝胶状动物浮游生物数据将用于模型的制定、初始化和实地验证。该项目符合美国国家科学基金会的职业规划目标，因为它将允许胡德博士将他目前的生态系统建模研究扩展到基于个体和拉格朗日粒子轨迹建模的领域，并开发一个专注于切萨皮克湾的研究项目。后者将促进与参与切萨皮克湾项目和LMER-TIES的科学家的互动。该项目还将允许首席研究员在他的一般专业领域开设一门课程。这门课程是必要的，因为它将提供生物学家进行耦合生物和物理建模研究所需的基本训练，它是独特的，因为研究将形成教学的基础。希望这次培训最终将促进生物和物理科学家之间的相互作用，并促进更多关于海洋系统中生物和物理相互作用的跨学科研究。

9628888 Hood This is a four year Faculty Early Career Development (CAREER) award which includes both a basic science and a course development component. The research will develop and apply a generalized Lagrangian particle trajectory model for the Chesapeake Bay which will then be used to develop an individual based, coupled biologic al and physical model of the sea nettle. This research will have two principle goals: The first is to provide a general particle trajectory model for the Chesapeake Bay research community that can be used as a tool for physical, chemical and biological research in the Bay. The second is to use the model to study how the interacti on between physical and biological processes determines the time and space distributions of and the impact the sea nettle has upon its prey in the Chesapeake Bay. The 3-dimensional, time-dependent flow will be provided by a hydrodynamic circulation model which was developed as part of the Chesapeake Bay Program. Gelatinous zoopla nkton data from the NSF LMER-TIES field observational program will be used for model formulation, initialization and groundtruthing. The project meets the NSF's CAREER program objectives because it w ill allow Dr. Hood to broaden his current ecosystem modeling research into the realm of individual based and Lagrangian particle trajectory modeling and develop a research program that focuses on the Chesapeake Bay. The latter will foster interaction with scient ists involved in the Chesapeake Bay Program and LMER-TIES. The project will also allow the principle investigator to develop a course in his general area of specialization. This course is needed because it will provide the basic training that biologists need to carry out coupled biological and physical modeling research and it is unique because the research will form the basis for instruction. It is hoped that this training will ultimately facilitate interaction between biological and physical scient ists and foster more interdisciplinary research on biological and physical interactions in marine systems.
