SGER: Participation in Italian Ross Sea Expedition

该SGER提案是霍恩波因特实验室、马里兰州大学环境科学中心和的里雅斯特大学以及意大利的里雅斯特海洋生物学实验室之间合作的产物。它是为了支持DK Stoecker和一名研究生在2002-2003年南半球夏季参加意大利罗斯海考察。最近开发的技术，以调查温带，沿海水华形成藻类的个体生态学和种群动态将被应用于罗斯海的极地原生生物。这项合作提供了一个难得的机会，以比较微型浮游动物放牧在温和和极地系统中的水华动力学中的作用，确定极地微型浮游生物是否具有细胞外蛋白酶活性，并从罗斯海获得光合纤毛虫，红中缢虫及其crytophytealgae“猎物”的样品进行分子分析。此外，这次航行将有助于极地科学研究生的教育，并为他的论文提供材料。这也将有助于UMCES与意大利的里雅斯特海洋生物实验室之间的持续合作。

This SGER proposal is an outgrowth of collaboration between Horn Point Laboratory,University of Maryland Center for Environmental Science and the University of Trieste andthe Laboratory for Marine Biology, Trieste, Italy. It is to support the participation ofDK Stoecker and a graduate student in an Italian expedition to the Ross Sea during theaustral summer 2002-2003. Techniques which have been recently developed to investigatethe autecology and population dynamics of temperate, coastal bloom-forming algae will beapplied to polar protists from the Ross Sea. This collaboration presents a tremendousopportunity to compare the role of microzooplankton grazing in bloom dynamics in temperateand polar systems, determine if polar microplankton have ectocellular protease activityand to obtain samples of the photosynthetic ciliate, Mesodinium rubrum and its crytophytealgal "prey" from the Ross Sea for molecular analysis. Futhermore, the cruise wouldcontribute to the education of a graduate student in polar science and provide materialfor his dissertation. It would also contribute to continued collaboration between UMCESand the Marine Biological Laboratory in Trieste, Italy.
