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.

小行星9525809 南大洋是全球碳循环中一个非常重要的区域，但那里的地球化学循环还没有得到很好的理解。这种缺乏了解的部分原因是观测不足，但这也是控制绕极流生物学和化学的空间尺度多样性的结果--从中尺度到全球尺度。 来自马萨诸塞州理工学院的海洋模型专家团队将通过模拟碳的质量平衡及其各种转化途径，重点研究影响中尺度和更高空间尺度营养物质、无机和有机碳的生产、消费和运输的生物、化学和物理过程。示踪剂研究将把这些过程分解到涡流的水平。然后，在确定南大洋海洋生物种群的斑块分布时，将考虑涡旋的作用。最后，这项模拟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状况中的作用。
