Description :
The variation in near-surface ground-ice content of the uppermost 1 m of permafrost was examined by drilling 71 sites within the Kendall Island Bird Sanctuary of the outer Mackenzie Delta, Northwest Territories. The primary aims of the research were : 1) to characterise near-surface ground-ice conditions by terrain type; 2) to investigate the geomorphological controls on ground-ice development; and 3) to estimate, for alluvial wetlands, the combined effect of potential subsidence from ground-ice degradation and relative sea-level rise.
