Description
Summary:ABSTRACT. 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 thicknesses for particular cover components. It is suggested that maps combining the three years ' data and displaying the resulfs in terms of means and standard deviations.provide a useful basis for designing ice and snow surveys in medium-sized lakes in snowy environments. Key words: lake ice, lake snow, ice survey, white ice; black ice, winter limnology, Labrador RkSUMfi. Des donnkes receuillies sur une p6riode de trois ans et fondtes sur des khantillons pris an hasard et en nombres nettement plus dlev6s qu'8 I'ordinaire, sont rassembks en vue de caractdriser la neige en fin de fdvrier et la glace blanche et.noire du lac filisabeth, au Labrador. Des distributions semblables semblent exister d'annk en ann&,.les bhantillons centraux et marginaux &ant de fawn consistante d'un 6paisseur au-dcssous ou endessous de la moyenne quant aux couches partieu!i&res. Il est suggdrd que les cartes combinant les donnks des trois ans et indiquant les hultats en termes de moyenms et de ddviations standards constituent une base utile pour la conception de lev&s de glace et de neige pour les lacs de taille moyenne dans des milieux enneigds.
