Phytoplankton Composition and Photosynthetic Properties Associated with Water Masses in the George V Region of Antarctica

乔治五世海岸（东经140 - 150度）是南极洲一个未被充分研究的沿海地区。这项探索性研究的小额赠款为一个重点关注沿海沿着大陆架和底层水形成的项目增加了生物组成部分。这项研究将确定该区域生物海洋学的基本资料，特别是其生产力与当地水文场的关系。具体目标是：1）绘制叶绿素a分布图和该地区浮游植物的光合能力，2）通过直接显微分析确定该地区浮游植物和微型浮游动物种群的特征，3）测量各种水体中的硝酸盐和硅酸盐水平。这些目标将提供以下方面的资料：生物生产在多大程度上与区域水团有关;当地生产的生物性质;浮游生物功能群与该区域水团之间的联系;浮游植物生长与养分消耗之间的相互作用。研究结果可作为关于该地区生物生产和通量的更广泛假设的基础，并有可能促进对研究不足的南大洋的进一步研究。

The George V Coast (140 - 150 degrees E) is an understudied coastal region of Antarctica. This Small Grant for Exploratory Research adds a biological component to a project focusing on the shelf and bottom water formation along the coast. This research will determine basic information on the biological oceanography of the region and in particular, how its productivity is related to the local hydrographic fields. The specific goals are 1) to map the chlorophyll a distribution and the photosynthetic capacity of the phytoplankton of the regions, 2) to characterize the phytoplankton and microzooplankton populations in the region by direct microscopic analysis, and 3) to measure nitrate and silicate levels in the various water masses. These goals will provide information on to what extent biological production relates to regional water masses, on the biological nature of the local production and the association between function groups of plankon and the water masses of the region, and on the interaction between phytoplankton growth and nutrient draw-down. Results from the study can be used as the basis for more extensive hypotheses about the biological production and flux in the region and are likely to catalyze further research in the understudied Southern Ocean.
