Oceanic sediments harbor most of the world's biodiversity, primarily comprised of minute organisms that perform key ecological functions such as nutrient cycling, critical to the biodegradation of hydrocarbons. Unfortunately, knowledge of these communities of organisms in the Gulf of Mexico is sparse, thus precluding informed mitigation and remediation of the BP Deepwater Horizon oil spill. Knowledge-based action requires that three key questions be addressed: 1) How unique are the sediment communities in the Gulf? 2) How structured are the sediment communities within the Gulf? and 3) What has been the effect of anthropogenic disturbance on these communities? Cutting-edge, high-throughput DNA sequencing technologies will be employed, together with traditional taxonomic methods to assay the diversity of virtually all complex organisms from sediment samples collected prior to the April 2010 spill, representing diverse habitats across the Gulf of Mexico. The BP Deepwater Horizon oil spill represents a dramatic anthropogenic event of historic proportions. It will both require and inspire the interest of future biologists for decades. This funding will specifically provide new opportunities for student engagement in the long-term characterization of biodiversity, using new tools to understand the response of organisms to environmental change and the consequences, mitigation and remediation of such an environmental disturbance. Training will include support for undergraduate students to attend a workshop in Gulf of Mexico biodiversity assessment as well as graduate and postdoctoral training. In all cases participation by underrepresented groups in science will be actively encouraged. Most importantly, all data collected will be made openly accessible to the public and scientific communities to facilitate ongoing research and maximize the engagement of all stakeholders.

海洋沉积物具有世界上大部分生物多样性，主要由微小生物体组成，这些生物具有关键的生态功能，例如营养循环，对碳氢化合物的生物降解至关重要。不幸的是，对墨西哥湾的这些生物体社区的了解很少，因此排除了对BP Deepwater Horizo​​n油泄漏的知识缓解和修复。基于知识的行动要求解决三个关键问题：1）海湾中的沉积物群落的独特性如何？ 2）海湾内的沉积物群落的结构如何？ 3）人为障碍对这些社区的影响是什么？将采用尖端的高通量DNA测序技术，以及传统的分类方法，以分析2010年4月溢出之前收集的沉积物样品的几乎所有复杂生物的多样性，代表了墨西哥湾整个海湾的多样栖息地。 BP Deepwater Horizo​​n漏油代表了历史比例的戏剧性人为事件。几十年来，它既需要并激发未来生物学家的兴趣。这项资金将专门为学生参与生物多样性的长期特征提供新的机会，并使用新工具来了解生物对环境变化的反应以及对这种环境骚扰的后果，缓解和修复的后果，缓解和修复。培训将包括支持本科生参加墨西哥生物多样性评估以及研究生和博士后培训的研讨会。在所有情况下，将积极鼓励代表性不足的科学团体参与科学。最重要的是，所有收集的数据都将公开访问公共和科学社区，以促进正在进行的研究并最大程度地提高所有利益相关者的参与。
