Examining the link between climate and zooplankton productivity is essential due to the important role of zooplankton in the transport of photosynthetically produced organic matter and passing it up the marine food web to higher trophic levels. Copepods (small crustaceans) form the major part of zooplankton in the North Atlantic Ocean and are the main food source for young fish.The proposed project addresses how changes in the distribution and productivity of copepod populations are linked to climate-driven physical processes and compares regional differences on the North European (incl. North Sea) and the American Continental Shelf. Both sites are linked by pan-regional climate patterns. The scientific questions, e.g. What causes biogeographical boundaries in some species not present in others?, are investigated by numerical models, which describe the marine ecosystem by matter fluxes (i.e. exchange of carbon and nutrients between different components and transport through ocean currents).The link to international projects (GLOBEC, BASIN) allows input through scientific collaboration and can be a valuable contribution to these research programs.

研究气候和浮游动物生产力之间的联系是必要的，因为浮游动物在光合作用产生的有机物质的运输中起着重要作用，并将其传递给海洋食物网到更高的营养水平。桡足类（小型甲壳类动物）是北大西洋浮游动物的主要组成部分，也是幼鱼的主要食物来源。拟议中的项目研究桡足动物种群分布和生产力的变化如何与气候驱动的物理过程联系起来，并比较了北欧（包括北海）和美国大陆架的区域差异。这两个地点都被泛区域气候模式联系在一起。科学问题，例如，是什么导致某些物种的生物地理界限在其他物种中不存在？数值模型通过物质通量（即不同组分之间碳和营养物质的交换以及通过洋流的运输）来描述海洋生态系统。与国际项目（GLOBEC， BASIN）的联系允许通过科学合作投入，并可以为这些研究项目做出宝贵贡献。
