Groundwater is a crucial life-sustaining resource that supplies water to ~10 million Canadians, surface waters and ecosystems. I examine groundwater systems at regional (10s km) to continental (1000s km) scales, which I refer to as 'mega-scale'. Examining mega-scale groundwater systems is rare yet essential for a number of important fundamental and applied problems have emerged in the geoscience and engineering communities. These problems include the distribution of permeability in the earth, the nature of the water table and the potential for groundwater discharge to buffer ocean acidification.

地下水是维持生命的重要资源，为大约1 000万加拿大人、地表沃茨和生态系统提供水源。我检查地下水系统在区域（10公里）大陆（1000公里）的规模，我称之为“超大规模”。研究大型地下水系统虽然罕见，但对于地球科学和工程界出现的许多重要基础和应用问题来说却至关重要。这些问题包括渗透性在地球上的分布、地下水位的性质以及地下水排放以缓冲海洋酸化的可能性。
