Hall, Roland I. - University of Waterloo

个人简介

Professor Hall's research combines fields of aquatic ecology, paleolimnology and multivariate statistics to assess effects of multiple stressors on lakes, wetlands and reservoirs. Professor Hall manages the WATER Lab (University of WATerloo Environmental change Research Lab), a facility dedicated to the analysis of long term environmental records to address ecological issues. Much of our research focuses on water-rich northern landscapes, including: the Peace-Athabasca Delta (northern Alberta), Slave River Delta and a region north of Yellowknife (NWT), Old Crow Flats (Yukon) and Hudson Bay Lowlands (northern Manitoba).

研究领域

Professor Hall’s research centers on improving our understanding of the roles of natural processes and human activities on hydroecological conditions of northern water-rich landscapes. He achieves this by integrating contemporary hydroecological studies with long-term records of past environmental change obtained from lake sediment cores. Sampling is typically conducted at a landscape scale. Research has targeted ecologically and culturally important deltaic (Peace-Athabasca Delta [PAD, AB] and Slave Delta [SD, NWT]), and thermokarst landscapes (Old Crow Flats [OCF, YT]; Hudson Bay Lowlands [HBL, MB]) landscapes, where insufficient understanding of influential processes has fostered controversy or impeded development of effective stewardship. The deltaic landscapes are situated downstream of major energy projects (hydroelectric dams, Alberta oil sands operations) and natural sources of contaminant dispersal, and they respond sensitively to climate-driven variations in river flow. At the thermokarst landscapes, local communities, First Nations organizations and Parks Canada Agency are concerned about effects of climate warming on the freshwater resources.
