Ground ice conditions near Rea Point and on Sabine Peninsula, eastern Melville Island
Using data obtained in the winter of 1981–1982 from trench excavations in the vicinity of Rea Point, volumetric ice contents with depth have been calculated for Paleozoic age (Weatherall, Griper Bay, and Hecla Bay formations) and Quaternary age (alluvium and deltaic sands) sediments. In addition, bo...
