Distribution, Abundance, and Energy Utilization of Zooplankton and Micronekton from a Winter Ice Edge.

南极冬季是许多远洋生物群落生活史上的一个关键时期，而远洋生物群与冬季冰缘的关系尚未被探索。1988年冬季，利用中水拖网技术和垂直网拖网技术，研究了南极边缘冰带附近微浮游生物和浮游动物群落的组成、丰度和垂直、水平结构。在开阔水域、边缘冰带和浮冰为主群落的水柱上1000m处取样。此外，通过直接分析食料，研究了各主要物种的摄食模式，通过直接分析耗氧量，研究了各物种的代谢，以及它们的近似和元素组成。所得数据提供了对冬季和冬季冰缘的完整反应，从个体的生理和化学组成到浮游动物和微浮游动物群落的垂直和水平结构。该奖项将允许对所有数据集进行完整的分析。

The Antarctic winter season is a critical period in the life-histories of much of the pelagic community, and the relation of the pelagic biota to the winter ice edge is unexplored. The composition, abundance, and vertical and horizontal structure of the micronekton and zooplankton communities in the vicinity of a marginal ice zone was examined during the austral winter, 1988, using midwater trawling techniques and vertical net tows. Sampling was conducted in the upper 1000m of the water column in the open water, marginal ice zone, and pack-ice dominated communities. In addition, the feeding patterns of all major species were studied through direct analysis of diet, metabolism of all species through direct analysis of oxygen consumption rate, and their proximate and elemental composition. The resultant data gives a complete spectrum of response to the winter season and the winter ice edge, from the physiology and chemical make-up of the individuals to the vertical and horizontal structure of the zooplankton and micronekton communities. This award will allow for the complete analysis of all data sets.
