Sampling of Snow and Ice on Lakes

Three years' data, based on unusually large random samples, are combined to characterize the late February snow, white ice, and black ice cover of Elizabeth Lake, Labrador. Similar spatial patterns were found to exist between years with central and marginal locations tending to exhibit consistently above- or below-average thickness for particular cover components. It is suggested that maps combining the three years' data and displaying the results in terms of means and standard deviations provide a useful basis for designing ice and snow surveys in medium-sized lakes in snowy environments.
