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

在过去的30年里，在整个种群水平上对细菌与浮游植物之间的关系进行了评估。天然样本核酸分析的最新进展表明，微生物的多样性比以前认为的要大；然而，尽管有大量证据表明这些种群是紧密耦合的，但尚未试图阐明细菌和浮游植物多样性之间的联系。科克霍夫博士将识别在沿海海洋上升流中受到刺激的特定细菌和浮游植物。他将以初步证据为基础，证明1995年新泽西州外海的上升流事件中细菌和浮游植物之间存在联系。Kerkhof博士将使用分子工具与最先进的观测网络和船上采样相协调，进一步阐明在中大西洋湾（MAB）的四个上升流事件（14周）中细菌和浮游植物之间的这些联系。这项研究将提供一个前所未有的图片微生物群落过程，多样性和动态在沿海海洋的偶发事件。最终，对MAB微生物过程的理解将有助于开发近岸沿海海洋的预测能力，以预测区域和全球生物地球化学循环。

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.
