图2 南大洋区域2个断面的表层海水观测数据（2006.11 ~ 2006.12） （a）SeaWiFS 8天平均叶绿素数据, 红线（向北航行）和黑线（向南航行）分别代表船的航线, 白色区域代表海冰或云层覆盖区域；（b）船载走航荧光观测叶绿素数据；（c）走航表层海水温度（SST）及海冰覆盖率。箭头表示北亚南极峰（NSAF）, 南亚南极峰（SSAF）, 极峰（PF）, 南极绕极流南部峰（SACCF）位置；（d）走航表层海水△O 2 Ar及净生产力（NCP, Net community production）数据；（e）走航表层海水pCO 2 值, 虚线为大气pCO 2 值（f）走航表层海水DMS浓度值 [ 26 ]
Fig 2 Surface water property distributions along two Southern Ocean transects, Nov ~ Dec. 2006. （a）Chlorophyll α concentrations were derived from Sea WiFS 8-day men composite data , red line （Northward）and black line（Southward） show the ship position, while white areas denote the presence of sea ice or cloud cover；（b）ship-based underway fluorometric analysis Chlorophyll α concentration；（c）Surface seawater temperature and ice cover rate；（d）Surface seawater △O 2 Ar value and NCP value.（e）Surface seawater pCO 2 data and Dashed line shows the atmospheric pCO 2 level；（f）Surface seawater DMS concentrations [ 26 ]
