Individual Based Modeling of Particles and Pelagic Organisms in Chesapeake Bay

小行星9628888 这是一个为期四年的教师早期职业发展（CAREER）奖，其中包括基础科学和课程开发组件。 这项研究将开发和应用一个广义拉格朗日粒子轨迹模型的切萨皮克湾，然后将用于开发一个个人为基础的，耦合的生物学和物理模型的海荨麻。 这项研究将有两个主要目标：第一个是提供一个通用的粒子轨迹模型的切萨皮克湾的研究社区，可作为一种工具，在海湾的物理，化学和生物研究。二是利用该模型研究物理过程和生物过程的相互作用如何决定切萨皮克湾海荨麻的时空分布及其对猎物的影响。三维、随时间变化的流动将由作为切萨皮克湾计划一部分开发的水动力循环模型提供。来自NSF LMER-TIES现场观测计划的胶质动物园nkton数据将用于模型制定，初始化和地面实况。 该项目符合美国国家科学基金会的职业生涯计划的目标，因为它将允许胡德博士扩大他目前的生态系统建模研究到个人为基础的领域和拉格朗日粒子轨迹建模和开发一个研究计划，重点是切萨皮克湾。后者将促进与参与切萨皮克湾计划和LMER-TIES的科学家的互动。该项目还将使主要调查员能够在其一般专业领域开设一门课程。本课程是必要的，因为它将提供生物学家需要进行耦合生物和物理建模研究的基本培训，它是独一无二的，因为研究将形成教学的基础。 希望这次培训将最终促进生物和物理科学家之间的互动，并促进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.
