This proposal was submitted in response to the CAREER Program Announcement and contained both scientific and educational goals.The ultimate scientific goals of this proposed study are to understand how physical and biological processes (bioturbation) interact to produce indificual sedimentar units and the sedimentary record in general. The project will collect a wide variety of environmental data at four (4) selected sites in the Gulf of Mexico, and samples to examine the sedimentary record, physical processes of sedimentation, and bioturbation. The four (4) sites vary significantly to terms of rates of deposition and rates of bioturbation. Finally, the results will be compared with quantitative forward models that attempt to quantify the effects of physical and biological variables, and with mesocosm laboratory experiments in which benthic fauna interact with sediment in the lab.The educational aspects of the proposal included: undergraduate outreach to students at regional HBCU's curse development, student participation in proposed research efforts, and adopting the models developed for use as teaching aids.

本研究的最终科学目标是了解物理和生物过程（生物扰动）如何相互作用，从而产生单个沉积单元和一般的沉积记录。 该项目将在墨西哥湾的四（4）个选定地点收集各种环境数据，并采集样本以检查沉积记录、沉积的物理过程和生物扰动。 这四（4）个地点在沉积速率和生物扰动速率方面存在显著差异。 最后，将把研究结果与试图量化物理和生物变量影响的定量前向模型进行比较，并与在实验室中进行的底栖动物与沉积物相互作用的中型生态系统实验室实验进行比较。在区域HBCU的诅咒发展，学生参与拟议的研究工作，并采用所开发的模型作为教学辅助工具。
