The Use of Satellite Imagery for Monitoring Ice Break-up along the Mackenzie River, N.W.T.

Abstract

The usefulness of satellite imagery for providing comprehensive information concerning break-up of river ice is discussed. For the years 1975-77, dates of break-up along the Mackenzie River derived from satellite images correlated well with the dates noted at six ground stations in the valley. It is suggested that satellite imagery could also be used to study ice break-up along rivers where little or no hydrometeorological data are regularly collected.
