Autumn Ecology of the Pack Ice Biota

季节性的浮冰覆盖了南部的大片地区 海洋 浮冰中的生物群遍布整个浮冰， 这要归功于 从水中分离出来的生物体。 的 频繁形成的冰和集中的 新形成的冰层中的生物是 浮冰和陆地固定冰栖息地之间的差异。 在秋季到冬季的过渡光照水平， 大气温度下降，大量的 季节性海冰形成。 融入浮冰的生物 在这个季节将受到低温，高， 原位盐度和低光照。 本项目将研究 将有机体掺入冰中以确定 如果选择发生，如果生物体存活，如果一些生物体 形成休眠期作为确保越冬生存的手段。 这是一项国际多学科研究的一部分， 积冰系统 该项目将是一个关键部分， 合作，重点是生物，物理和化学 在秋季冰形成的季节。

Seasonal drifting pack ice covers vast regions of the Southern Ocean. The biota in pack ice are found throughout the ice floes, and this has been attributed to the harvesting and concentration of organisms from the water during frazil ice formation. The frequent formation of frazil ice and the concentration of organisms in newly-forming ice is one of the fundamental differences between the pack ice and the land fast ice habitats. During the autumn to winter transitional light levels and atmospheric temperatures decrease and a considerable amount of seasonal sea ice forms. Organisms incorporated into ice floes during this season will be subjected to low temperature, high in situ salinities and low light. This project will examine the process of the incorporation of organisms into ice to determine if selection occurs, if organisms survive and if some organisms form resting stages as a means for insuring overwinter survival. This is part of an international, multidisciplinary study of the pack ice system. This project will be a key part of the collaboration, which focuses on biological, physical and chemical processes during the autumn ice-forming season.
