Four determinations of gravity were made during the summer of 1948, with the pendulum apparatus of the Dominion Observatory, at Goose Bay, Labrador (latitude 53°), Frobisher Bay, Baffin Island (latitude 64°), Resolute Bay, Cornwallis Island (latitude 75°), and Thule, Greenland (latitude 77°), approximately. The anomalies at the two most northerly stations are comparatively small and those at the other two stations, although larger, do not exceed many that have been observed in other parts of Canada. Norgaard's determination at Thule is confirmed by the author.It is anticipated that these determinations, apart from their immediate interest, will serve as useful reference points for future work in the Canadian Arctic.

AbstractThe 10 m temperatures were measured over several years at 16 sites on the White Glacier (lat. 80° N.), Axel Heiberg Island, Canadian Arctic Archipelago. At three sites deep profiles were made using a new drilling technique, reaching a maximum depth of 280 m. Large differences in the 10 m temperatures between locations and from year to year were observed. The deviations of these temperatures from the almost isothermal mean annual air temperature over the glacier are discussed. The heating effect of the melt water in the lower percolation zone was found to be very important. A conceptual model is developed to assess the influence of these irregularities in the energy input at the upper boundary on the thermal regime of the entire glacier. So far a quantitative analysis has been made only for the relatively simple 30 m temperature profile measured on the tongue of the glacier.
