Antarctic Marine Ecosystem Research at the Ice Edge Zone (AMERIEZ): The Distribution of Free-Living Protozoa

在初春达到最大程度时，南极的积冰覆盖的面积大致相当于南极大陆的面积；到夏末，威德尔海和其他沿海地区只剩下残留物。因此，冰缘带是南极地区的一个主要特征，在每年的周期中的某个时候，冰缘带包括了周围的大部分海洋。冰缘的生产力似乎高于开阔大洋或浮冰区域，并假设冰缘是鸟类和哺乳动物的重要觅食区。为了更好地了解冰缘对南极生产力和生态的整体重要性，开发了一项多学科计划，以获取冰缘带的物理、化学和生物学数据。加里森的项目是AMERIEZ(南极冰缘地带海洋生态系统研究)计划的一部分。该项目目前正处于最后分析和综合阶段。该项目将完成对冰缘附近原生动物的检查，以确定它们的丰度、分布、物种组成和在食物网中的作用。这是一个基于成就的续订。

At its maximum extent in the early spring, antarctic pack ice covers an area roughly equal to that of the antarctic continent; by late summer only remnants remain in the Weddell Sea and other coastal areas. Thus, the ice edge zone is a major feature of the antarctic region and one that includes most of the surrounding seas at some time during the annual cycle. Productivity at the ice edge appears to be higher than in either the open ocean or pack-ice region, and it has been hypothesized that the ice edge is an important feeding area for birds and mammals. A multidisciplinary program was developed to obtain data on the physics, chemistry, and biology of the ice-edge zone in order to better understand the overall importance of the ice edge for antarctic productivity and ecology. Garrison's project is one component of this program AMERIEZ (Antarctic Marine Ecosystem Research at the Ice Edge Zone). This project is now in its final analysis and synthesis stage. This project will complete the examination of the protozoans in the vicinity of the ice edge to determine their abundance, distribution, species composition, and role in the food web. This is an Accomplishment Based Renewal.
