Collaborative Research: Nitrate Flux Associated with Vertically Migrating Phytoplankton in the Central North Pacific Gyre

小行星9423561 这一建议将解决生物海洋学格式的一个基本问题，他的观点，垂直迁移的藻席在开放的海洋是在北太平洋的表面沃茨内的氮重新分配工具。 该项目将利用之前资助的船期，记录根管藻垫在整个上层100-300 m的垂直分布、氮的定量输入以及北太平洋环流中部垫在表层释放NO3的潜力。 该研究将通过这些宏观关联来表征起源深度、迁移时间和绝对运输速率，并确定其他环境浮游植物是否吸收了垫腐烂释放的NO3。 此外，该研究还将调查其他可能是垂直迁移者的浮游植物，如筛盘藻、甲藻、Halospaera和孤独的Pingulosolenia，以确定它们是否也是这一过程的重要组成部分。 在研究结束时，该项目将检查夏威夷以东和以西的北太平洋环流中心的沃茨。 这将导致对北太平洋环流海洋沃茨中浮游植物垂直迁移重要性的广泛空间理解。

9423561 Lipschultz This proposal will address a fundamental problem in biological oceanography format he viewpoint that vertically migrating algal mats in the open ocean are instrumental in redistributing nitrogen within the surface waters of the North Pacific Ocean. Using previously funded shiptime, the project will documents Rhizosolenia mat vertical distribution throughout the upper 100-300 m, the quantitative N inputs, and potential for NO3-release in the surface layers by mats in the central North Pacific gyre. The research will characterize depth of origin, migration times and absolute transport rates by these macroscopic associations and determine if NO3-release by mat decay is taken up by other ambient phytoplankton. In addition, the study will survey other phytoplankton that may be vertical migrators such as Ethmodiscus, Pyrocystis, Halospaera and solitary Phizosolenia to determine if they are also important components of this process. At the conclusion of the study, the project will have examined waters of the central North pacific gyre both east and west of Hawaii. This should lead to a broad spatial understanding of the importance of phytoplankton vertical migration in the oceanic waters of the North Pacific gyre.
