BaySys - Contributions of climate change and hydro-electric regulation to the variability and change of freshwater-marine coupling in the Hudson Bay system

该项目将研究淡水在哈德逊湾海洋和沿海系统中所起的作用。这将为区分气候变化和淡水水电调节对哈德逊湾物理、生物和生物地球化学条件变化的相对影响提供科学依据。这项研究将为马尼托巴省水电公司关于马尼托巴省北部纳尔逊河下游现有基础设施运营和未来发展规划的决策提供信息。该项目包括两个核心实地工作部分。整个海湾的工作将在CCGS Amundsen号上进行，这是一艘研究破冰船，为进行科学研究提供了一个安全的平台。来自阿蒙森的工作将专注于在春季融化季节从大片空间区域收集数据。“河口”的工作重点将是对比丘吉尔(低)和纳尔逊(高)流入河口的情况。这将在冬末利用马尼托巴省吉拉姆的后勤基地和哈德逊湾边缘的野战营地来完成。这两个实地组成部分将得到遥感数据、海洋和大气观测站以及数值模拟研究的支持。

This project will study the role that freshwater plays in the Hudson Bay marine and coastal systems. It will provide a scientific basis to separate the relative effects of climate change from those of hydroelectric regulation of freshwater on changing physical, biological and biogeochemical conditions in Hudson Bay. This research will inform decision-making by Manitoba Hydro with respect to existing infrastructure operations and planning for future development on the lower Nelson River in Northern Manitoba. The project includes two core fieldwork components. 'Bay-wide' work will be conducted aboard the CCGS Amundsen, a research icebreaker that provides a safe platform from which to conduct scientific studies. Work from the Amundsen will focus on collecting data from a large spatial area during the spring melt season. 'Estuary' work will focus on contrasting the Churchill (low) and Nelson (high) outflows into estuaries. This will be done in late winter using a logistics base in Gillam, Manitoba, and a field camp on the edge of Hudson Bay. Both field components will be supported by remotely-sensed data, ocean and atmospheric observatories and numerical modeling studies.
