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上最剧烈的温度变化，导致海冰密度和覆盖范围的显著变化。研究表明，这些变化正在引起该地区生态的重大变化；然而，人们对这些海冰变化对冬季群落的影响知之甚少。这项研究将为美国南极海洋生物资源（AMLR）冬季巡航增加浮游细菌取样工作。最先进的定量PCR，基因组学技术和生物信息学将被用于测试关于冬季浮游细菌群落中化石化自养作用的新假设。整个AMLR调查区域的浮游生物生物量也将被确定，并与AMLR小组共享，以产生更全面的数据集，描述冬季生态系统的状态。研究结果将通过出版物以及在国家和国际会议上的发言得到广泛传播。此外，原始数据将通过开放获取的数据库提供。此外，这个项目将有助于研究和培养研究生。最后，这项工作将有助于透过邮轮网站博客与公众接触。
