RAPID: Assessing Winter Bacterioplankton Distributions and Carbon Cycling as part of AMLR Field Program, August 2012

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面积发生显著变化。研究表明，这些变化正在导致该地区生态的重大变化;然而，人们对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冬季巡航增加浮游细菌采样工作。国家的最先进的定量PCR，基因组学技术和生物信息学将被用来测试新的假设的作用，冬季浮游细菌群落的chemolithoautotrophy。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，以生成描述冬季生态系统状态的更全面的数据集。将通过出版物以及在国家和国际会议上的发言广泛传播成果。此外，将通过开放式数据库提供原始数据。此外，本项目将有助于研究生的研究和培训。最后，这项工作将通过游轮网络博客促进与公众的外联。

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.
