南极海洋生态系统——南极辐合带以南的植物、动物、海洋、海冰和岛屿组成部分的集合——是地球上最大的可定义生态系统之一（36 × 106 knl ~） （Hedgpeth, 1977; Petit et aI.）, 1991)。该生态系统由功能不同的水文和生物地球化学细分的相互关联的系统组成（Treguer和Jacques， 1992），包括开放海洋、锋面区、大陆架斜坡水域、海冰和边缘冰带。该系统中的海洋、大气和生物地球化学过程被认为具有全球意义，但很少被研究，相对于更容易获得的海洋生态系统，人们对其了解甚少（Harris and Stonehouse, 1991; Johannessen et al., 1994）。南极半岛以西的帕尔默长期生态研究区（帕尔默LTER）是一个复杂的海岸/大陆架带和季节性海冰带的组合，因为该地区每年都受到海冰的进退。帕尔默LTER项目是一个
T H E ANTARCTIC marine ecosystem--the assemblage of plants, animals, ocean, sea ice, and island components south of the Antarctic Convergence-is among the largest readily defined ecosystems on Earth (36 × 106 knl ~) (Hedgpeth, 1977; Petit et aI., 1991). This ecosystem is composed of an interconnected system of functionally distinct hydrographic and biogeochemical subdivisions (Treguer and Jacques, 1992) and includes open ocean, frontal regions, shelf-slope waters, sea ice, and marginal ice zones. Oceanic, atmospheric, and biogeochemical processes within this system are thought to be globally significant, have been infrequently studied, and are poorly understood relative to more accessible marine ecosystems (Harris and Stonehouse, 1991; Johannessen et al., 1994). The Palmer Long-Term Ecological Research (Palmer LTER) area west of the Antarctic Peninsula (Fig. la) is a complex combination of a coastal/continental shelf zone and a seasonal sea ice zone, because this area is swept by the yearly advance and retreat of sea ice. The Palmer LTER program is a
