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

在过去的30年里，在整个种群水平上评估了细菌和浮游植物之间的联系。在天然样品的核酸分析方面的最新进展表明，微生物多样性比之前认为的更大；然而，尽管有大量证据表明细菌和浮游植物多样性之间的联系是紧密相连的，但还没有人试图阐明它们之间的联系。科克霍夫博士将确定在沿海海洋上升流过程中共同刺激的特定细菌和浮游植物。他将建立在初步证据的基础上，证明细菌和浮游植物之间的联系，在1995年新泽西州附近的一次上升流事件中。Kerkhof博士将使用分子工具，配合最先进的观测网络和船上采样，进一步阐明在大西洋中部海湾(MAB)的四次上升流事件(14周)期间细菌和浮游植物之间的这些联系。这项研究将提供一幅史无前例的关于沿海海洋中微生物群落过程、多样性和动态的图景。最终，这种对人与生物圈微生物过程的了解将有助于发展近岸沿海海洋预测区域和全球生物地球化学循环的能力。

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.
