南大洋碳和气候观测与建模计划（SOCCOM）正在整个南大洋部署生物地球化学Argo浮标，剖面深度为2,000米。目标是到2020年达到200个浮标，以提供第一套完整的碳、氧、硝酸盐和光学特性的年度循环。从没有预先覆盖到稀疏阵列，部署基于水团属性的先验知识，平均锋面位置，平均环流和涡变，风，海气热量/淡水/碳交换，先前的Argo轨迹，以及南大洋状态估计和混合坐标海洋模型（HYCOM）中的浮动模拟。2014-2015年从南非到南极洲的Polarstern巡航中部署的12个浮标被用作测试案例，以评估SOCCOM迄今为止20次部署巡航和126个浮标所采用的部署策略。几年后，这些浮标继续代表预先设定的部署区域：（1）威德尔环流海冰区，观察南极斜坡锋和毛德海隆上十年罕见的冰间湖;（2）南极绕极流（ACC），包括地形转向的南部地区烟囱，其中上升的碳/营养丰富的深层沃茨产生惊人的大量二氧化碳释气;（3）大西洋-非洲之间的亚热带和亚热带;（4）开普盆地。Argo浮标和涡解HYCOM模拟是SOCCOM浮标路径的最佳预测因子，在海冰区2年后的不确定性为1,000公里，是ACC及其以北的两倍多。
Abstract Biogeochemical Argo floats, profiling to 2,000‐m depth, are being deployed throughout the Southern Ocean by the Southern Ocean Carbon and Climate Observations and Modeling program (SOCCOM). The goal is 200 floats by 2020, to provide the first full set of annual cycles of carbon, oxygen, nitrate, and optical properties across multiple oceanographic regimes. Building from no prior coverage to a sparse array, deployments are based on prior knowledge of water mass properties, mean frontal locations, mean circulation and eddy variability, winds, air‐sea heat/freshwater/carbon exchange, prior Argo trajectories, and float simulations in the Southern Ocean State Estimate and Hybrid Coordinate Ocean Model (HYCOM). Twelve floats deployed from the 2014–2015 Polarstern cruise from South Africa to Antarctica are used as a test case to evaluate the deployment strategy adopted for SOCCOM's 20 deployment cruises and 126 floats to date. After several years, these floats continue to represent the deployment zones targeted in advance: (1) Weddell Gyre sea ice zone, observing the Antarctic Slope Front, and a decadally‐rare polynya over Maud Rise; (2) Antarctic Circumpolar Current (ACC) including the topographically steered Southern Zone chimney where upwelling carbon/nutrient‐rich deep waters produce surprisingly large carbon dioxide outgassing; (3) Subantarctic and Subtropical zones between the ACC and Africa; and (4) Cape Basin. Argo floats and eddy‐resolving HYCOM simulations were the best predictors of individual SOCCOM float pathways, with uncertainty after 2 years of order 1,000 km in the sea ice zone and more than double that in and north of the ACC.
