Abstract
In situ measurements of permafrost creep at a number of sites near Rea Point, eastern Melville Island between 1985 and 1987 indicate rates of deformation between 0.06 to 0.10 cm/yr at a depth of 65 cm. The current mean annual ground temperature is -16.5C and ground temperatures warmer than -3.0C occur only in the top 1.0 - 1.2 m of permafrost and only for 80 - 100 days per year. If predicted global warming trends were to induce slight thermal changes in the upper 1.0 - 1.2 m of permafrost at Rae Point, greater creep rates might be expected in addition to increased gelifluction and mean mass wasting in the active layer.
