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. Manitoba Hydro has a vested interest in research on impacts and adaptation strategies for climate change on northern ecosystems as it may affect system operations and future generation developments. Results from this project will help Manitoba Hydro investigate ways to enhance the quality and capacity of environmental science in the regions in which it operates, produce reliable assessments of impacts of climate change on water supply, and increase our understanding of the effects of climate change on northern ecosystems. More broadly, Nunavut and Canada will benefit from a better understanding of how seasonal shifts in freshwater, sediment and nutrient delivery and climate change may affect primary and fisheries productivity, and transportation in Hudson Bay and how this may change under a future climate.

该项目将研究淡水在哈德逊湾海洋和沿海系统中扮演的角色。 它将提供科学的依据，以将气候变化的相对影响与淡水对哈德逊湾物理，生物学和生物地球化学变化变化的水力发电调节的相对影响分开。这项研究将为Manitoba Hydro关于现有基础设施运营的决策提供依据，并计划在曼尼托巴省北部纳尔逊河上的未来发展。 该项目包括两个核心现场工作组件。将在CCGS Amundsen上进行“整个海湾”的工作，这是一项研究破冰船，提供了一个安全的平台来进行科学研究。 在春季融化季节期间，来自阿蒙森的工作将集中于从大空间区域收集数据。 “河口”的工作将集中在对比丘吉尔（低）和纳尔逊（高）流出到河口中。 这将在冬季晚些时候使用吉拉姆，曼尼托巴省和哈德逊湾边缘的野战营的物流基地进行。 这两个田间成分都将由遥感的数据，海洋和大气观测值以及数值建模研究来支持。 Manitoba Hydro对研究对北部生态系统的气候变化的影响和适应策略的研究具有既得利益，因为这可能会影响系统运营和未来生成的发展。该项目的结果将有助于曼尼托巴水电研究在其运营的地区增强环境科学的质量和能力的方法，对气候变化对供水的影响的可靠评估，并增强我们对气候变化对北部生态系统影响的理解。 更广泛地说，努纳武特（Nunavut）和加拿大将受益于更好地了解淡水，沉积物和养分的季节性转变以及气候变化可能会影响主要和渔业的生产力，以及哈德逊湾的运输以及在未来气候下可能会发生变化。
