Black Sea Modeling Project: Plankton Dynamics and Nutrient Cycles

Ducklow OCE-9616305将使用一系列日益复杂的跨学科数值模式来研究黑海低营养层的一般环流、生物地球化学循环和浮游生物动力学。首先，将使用一维物理-生物耦合模型来加强我们对黑海深层内陆和陆架区域内的生物要素循环、远洋生态系统碳和能量流动以及微生物过程的理解。然后，三维研究将着眼于(A)区域尺度上的营养物质运输和浮游生物生产力的路径；(B)与大气环流的中尺度特征有关的叶绿素浓度的斑块；(C)大陆架与内部之间的营养物质和生物物质的交换。模型的结果将与几个国际项目收集的现场观测结果进行比较。

Ducklow OCE-9616305 The general circulation, biogeochemical cycling and plankton dynamics of the lower trophic level of the Black Sea will be investigated using a hierarchy of increasing complex interdisciplinary numerical models. First a one-dimensional coupled physical-biological model will be used to improve our understanding of the biogenic element cycling, pelagic ecosystem carbon and energy flow and microbial processes within the deep interior and shelf regions of the Black Sea. Then three-dimensional studies will look at (a) the pathways of nutrient transport and plankton productivity on the regional scale; (b) the patchiness of chlorophyll concentrations in relation to mesoscale features of the general circulation; and (c) the exchange of nutrients and biogenic materials between the shelf and interior. The model results will be compared with in-situ observations collected by several international programs.
