Bio-Geo Chemical Cycling Carbon in the Southern Ocean

南大洋是全球碳循环的重要区域，但其生物地球化学循环机制尚不清楚。在某种程度上，这种认识的缺乏可归因于观测的缺乏，但这也是控制环极流生物学和化学的多重空间尺度（从中尺度到全球尺度）的结果。这支来自麻省理工学院的海洋建模团队将通过模拟碳的质量平衡及其各种转化途径，专注于影响中尺度和更高空间尺度上营养物质、无机碳和有机碳的生产、消耗和运输的生物、化学和物理过程。示踪剂研究将把这些过程分解到漩涡的水平。然后，涡流的作用将被考虑在南大洋海洋生物种群的斑块分布的定义。最后，该模型研究的结果将与全球碳循环的其他模型相结合，以更好地评估南大洋在全球碳图景中的作用。

9525809 FLIERL The Southern Ocean is a region of great importance in the global carbon cycle, yet the biogeochemical cycling there is not well understood. In part this lack of understanding is attributable to paucity of observations, but it is also a consequence of the multiplicity of spatial scales that control the biology and chemistry of the Circumpolar Current-- from mesoscale to global scale. This team of ocean modelers from the Massachusetts Institute of Technology will focus on the biological, chemical, and physical processes affecting the production, consumption, and transport of nutrients, inorganic and organic carbon at mesoscale and higher spatial scales by modeling the mass balance of carbon and its various pathways of transformation. Tracer studies will resolve these processes down to the level of eddies. Then, the role of eddies will be considered in the definition of the patchy distributions of populations of marine organisms in the Southern Ocean. Finally, the results of this modeling study will be combined with other models of the global carbon cycle to better assess the role of the Southern Ocean in the global carbon picture.
