Illumination of the Linkages between Bacteria and Phytoplankton in the Coastal Ocean during Upwelling

在过去的30年里，细菌和浮游植物之间的联系在整个人口水平进行了评估。在自然样品中的核酸分析的最新进展表明，微生物多样性比以前认为的更大，然而，阐明细菌和浮游植物多样性之间的联系尚未尝试，尽管大量的证据表明，这些人口是紧密耦合。Kerkhof博士将确定特定的细菌和浮游植物在沿海海洋上升流期间共同刺激。 他将以1995年新泽西海域的一次上升流事件中细菌和浮游植物之间的联系为基础。 Kerkhof博士将使用分子工具与最先进的观测网络和船上采样的状态协调，以进一步阐明这些细菌和浮游植物之间的连接在四个上升流事件（1 - 4周）在大西洋中部湾（MAB）。这项研究将提供一个前所未有的微生物群落过程，多样性和动态在沿海海洋事件。最后，对人与生物圈中微生物过程的理解将有助于发展对近海岸海洋的预测能力，以预测区域和全球的生物地球化学循环。

Over the last 30 years, the connection between bacteria and phytoplankton at a whole population level has been evaluated. Recent advances in the analysis of nucleic acids in natural samples has demonstrated microbial diversity is greater than had previously been thought; however, elucidating the linkages between bacterial and phytoplankton diversity has not yet been attempted despite a great deal of evidence these populations are tightly coupled. Dr. Kerkhof will identify specific bacteria and phytoplankton co stimulated during upwelling in the coastal ocean. He will build on preliminary evidence demonstrating a linkage between bacteria and phytoplankton during an upwelling event off New Jersey in 1995. Dr. Kerkhof will use molecular tools coordinated with a state of the art observational network and shipboard sampling to further elucidate these connections between bacteria and phytoplankton during four upwelling events (1 4 weeks) in the Mid Atlantic Bight (MAB). The research will provide an unprecedented picture of microbial community processes, diversity, and dynamics during episodic events in the coastal ocean. Ultimately, this understanding of microbial processes in the MAB will aid in developing a predictive capability for the near shore coastal ocean to forecast regional and global biogeochemical cycling.
