The Southern Ocean is experiencing some of the most dramatic changes in temperature in the world, leading to marked shifts in sea ice density and cover. Research has shown that these shifts are causing major changes in the ecology of this region; however, little is known about the effects of these changes in sea ice on winter communities. This research will add a bacterioplankton sampling effort to a United States Antarctic Marine Living Resources (AMLR) winter cruise. State-of-the-art quantitative PCR, genomics techniques and bioinformatics will be used to test novel hypotheses about the role of chemolithoautotrophy in winter bacterioplankton communities. The biomass of the plankton across the AMLR survey region will also be determined, and shared with the AMLR group to generate a more comprehensive data set describing state of the winter ecosystem. Results will be widely disseminated through publication as well as through presentations at national and international meetings. In addition, raw data will be made available through open-access databases. As well, this project will contribute to the research and training of a graduate student. Finally, this work will facilitate outreach to the general public through a cruise web blog.

南大洋正在经历世界温度最大的一些变化，导致海冰密度和覆盖率发生了明显的变化。研究表明，这些转变导致该地区的生态发生重大变化。但是，这些变化对海冰对冬季社区的影响知之甚少。 这项研究将为美国南极海洋生物资源（AMLR）冬季巡游增添大细菌抽样工作。最先进的定量PCR，基因组学技术和生物信息学将用于测试有关化学杂志嗜酸菌在冬季细菌群群落中作用的新假设。还将确定AMLR调查区域浮游生物的生物量，并与AMLR组共享，以生成更全面的数据集，描述冬季生态系统的状态。结果将通过出版以及在国家和国际会议上的演讲来广泛传播。此外，将通过开放访问数据库提供原始数据。同样，该项目将有助于研究生的研究和培训。最后，这项工作将通过Cruise Web博客促进向公众推广。
