Modelling the Annual Cycles of Plankton Production in Subpolar Open Seas

亚极地公海正在接受审查，因为它们可能在 在全球二氧化碳（CO2）循环中发挥作用。虽然水平 生物生产和生产的命运是 调查中的核心问题，甚至控制机制， 副极地公海的生物生产水平是 不明白。 这个项目将重塑一个生态系统 低营养级生物模型与过程模型相结合 水平相互作用，包括浮游植物生产，放牧， 和养分再生，转化为一维的物理模型 海洋上层。 该模型将被开发和首次测试 与从地球上观测到的大量物理和生物学数据相比较， 海洋站P（50度N 145度W） 亚北极太平洋 物理-生物效应 将评估相互作用和营养复杂性。 模型 然后将适用于其他两个亚极地公海， 亚北极大西洋和亚南极环极海洋， 由于生物和物理过程有利于去除 二氧化碳从表层和它的封存在深处 海洋，被认为在全球二氧化碳循环中发挥着重要作用。

The subpolar open seas are under scrutiny for the role they may play in the global carbon dioxide (CO2) cycle. While the level of biological production and the fate of that production are central issues in the inquiry, the mechanisms controlling even the level of biological production in the subpolar open seas are not understood. This project will reformulate an ecosystem process model integrating a biological model of lower trophic level interactions, including phytoplankton production, grazing, and nutrient regeneration, into a one-dimensional physical model of the upper ocean. The model will be developed and first tested against the extensive physical and biological observations from Ocean Station P (50 Degrees N 145 Degrees W) in the open subarctic Pacific Ocean. Effects of physical-biological interactions and trophic complexity will be assessed. The model will then be applied to the other two subpolar open seas, the subarctic Atlantic and the subantarctic circumpolar ocean which, because of biological and physical processes favorable to removal of CO2 from the surface layer and its sequestration in the deep ocean, are thought to play a major role in the global CO2 cycle.
