Modeling the Black Sea Ecosystem: Coupled, 3D Models of Circulation, Plankton Dynamics and Biogeochemistry

里佐利 OCE-9633145 将使用一系列日益复杂的跨学科数值模型，研究黑海低营养层的大气环流、生物地球化学循环和浮游生物动态。首先，将使用一个一维物理-生物耦合模型，以提高我们对黑海深层内陆和大陆架区域内生源要素循环、远洋生态系统碳和能量流动以及微生物过程的认识。 然后进行三维研究，探讨（a）区域范围内营养物质输送和浮游生物生产力的途径;（B）叶绿素浓度与大气环流中尺度特征的关系;（c）大陆架和内陆之间营养物质和生物物质的交换。模型结果将与多个国际项目收集的现场观测结果进行比较。

Rizzoli OCE-9633145 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.
