A regional pigment retrieval algorithm for the Nimbus-7 Coastal Zone Color Scanner (CZCS) has been tested for the Southern Ocean. The pigment concentrations estimated with this algorithm agree to within 5 percent with in situ values and are more than twice as high as those previously reported. The CZCS data also revealed an asymmetric distribution of enhanced pigments in the waters surrounding Antarctica; in contrast, most surface geophysical properties are symmetrically distributed. The asymmetry is coherent with circumpolar current patterns and the availability of silicic acid in surface waters. Intense blooms (>1 milligram of pigment per cubic meter) that occur downcurrent from continental masses result from dissolved trace elements such as iron derived from shelf sediments and glacial melt.
一种用于 Nimbus-7 海岸带水色扫描仪（CZCS）的区域性色素提取算法已在南大洋进行了测试。该算法估算的色素浓度与现场值相差在 5%以内，比以前报告的浓度高出一倍以上。CZCS 数据还揭示了在南极洲周围水域中增强色素的非对称分布；相比之下，大多数表面地球物理特性呈对称分布。这种非对称性与环极流模式和表层水中硅酸的可用性相一致。从大陆物质顺流而下的强烈水华（每立方米超过 1 毫克色素）是由来自大陆架沉积物和冰川融水的溶解痕量元素如铁等引起的。
