This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).Funds are provided to determine how arctic zooplankton communities have varied over interannual to decadal periods, from regional to panarctic scales. The PI states the specific hypotheses that zooplankton biomass may be increasing, due to environmental changes, and that the prevalence of the dominant copepod in deeper waters, Calanus hyperboreus, may be eroded by smaller congeneric species. He will assess the validity of this hypothesis by (1) filling the regional data gap over the Canada Basin through analysis of zooplankton samples collected or to be collected by the himself between 2002-2011; (2) assembling available zooplankton and environmental data throughout the Arctic into a single data portal for a GIS-based and spatially explicit modeling of community structures, species abundances, biomass, and distributions; and (3) rescuing precious older ?unpublished? data sets and grey literature worldwide, many of which he has already assembled or will have full access to, that will strengthen and extend his modeling efforts back more than 50 years.

该奖项根据 2009 年《美国复苏和再投资法案》（公法 111-5）提供资金。资金用于确定北极浮游动物群落在年际到十年间、从区域到泛北极范围内的变化。 PI提出了具体的假设，即由于环境变化，浮游动物生物量可能会增加，并且更深水域中优势桡足类Calanus hyperboreus的流行可能会被较小的同属物种侵蚀。他将通过以下方式评估这一假设的有效性：(1) 通过分析 2002 年至 2011 年期间收集的或他自己收集的浮游动物样本，填补加拿大盆地的区域数据空白； (2) 将整个北极地区可用的浮游动物和环境数据汇集到一个数据门户中，以便对群落结构、物种丰度、生物量和分布进行基于地理信息系统和空间明确的建模； (3) 拯救珍贵的旧书？未发表？世界各地的数据集和灰色文献，其中许多他已经收集或将完全访问，这将加强和扩展他 50 多年前的建模工作。
