Regional Projections of Climate Change Effects on Ice Cover and Open-Water Duration for Ontario Lakes Using Updated Ice-Date Models

Includes bibliographical references. 'Updated models for predicting ice break-up and freeze-up dates and ice thickness, developed using measurements from a series of Canadian lakes, were applied to project ice conditions for the remainder of this century across four sets of spatial units in Ontario: inland fishery management zones, secondary watersheds, municipalities, and ecodistricts. The duration of the open-water period was estimated as the days between freeze-up and break-up dates.
