Abstract

An air-photograph inventory was made of the present glacierization of areas of East Baffin Island adjoining Ome Bay and Okoa Bay. Ice fields characterize the broad muntain summits of Home Bay, while Okoa Bay is an area of cirque glaciers. There is a 4:1 ratio of ice-covered areas Between Home Bay and Okoa Bay above 600 m a.s.l. in Okoa Bay 39% of empty cirques face south, whereas those with xisting glaciers are restricted to orientations with azimuths between 310 deg - 145 deg. Neither glacier length nor the observable recession in the home bay area show any significant difference with regard to aspect. Climatic parameters (snowfall and degree days) and synoptic-climatological studies do not explain the strong contrast between the two areas. Cool, cloudy summer conditions are associated with easterly flow components that should affect both areas. Differential lag effects between the ice bodies in the two areas may be responsible for some of the observed difference.
