Glider Shelf-Edge Nutrient Exchange (GliSENEx)

大陆架边缘是浅海（深度<200米）和深海之间的边界，在那里，水、营养物和其他物质的交换对大陆架海洋的初级生产、大气中产生的二氧化碳向深海内部的输出以及沿海环境的总体健康具有重要影响。卫星侦察通常显示，大陆架边缘是叶绿素浓度较高的区域，因此表明该区域的初级生产率高于大陆架内部。因此，陆架边缘是一个具有关键生态作用的区域。这项建议将审查马林大陆架硝酸盐通量的命运，以及它们与叶绿素和初级生产的关系。将新的营养传感器与滑翔机技术（评估通量）和先进的卫星算法（估计叶绿素浓度和初级生产率）结合起来执行这一项目，将更广泛地有力地证明滑翔机用于复杂的多学科生物地球化学研究的能力。

The shelf edge represents the boundary between the shallow coastal seas (<200 m deep) and the deep ocean, where the exchange of water, nutrients and other substances have important implications for shelf sea primary production, for the export of atmosphere derived carbon dioxide to the deep ocean interior and for the overall health of the coastal environment. Satellite reconnaissance routinely reveals the shelf edge to be a region of enhanced chlorophyll concentration and thus indicative of a region with high rates of primary production relative to the shelf interior. The shelf edge is thus a region with a key ecological role. This proposal will examine the fate of nitrate fluxes at the Malin Shelf, and their relationship to chlorophyll and primary production. The merging of novel nutrient sensors with glider technology (to assess the flux) and leading-edge satellite algorithms (to estimate chlorophyll concentration and primary production rates) to carry out this project will, more generally, produce a robust demonstration of the ability of gliders to be used for complex multidisciplinary biogeochemical studies.
