Abstract

Perennial springs located on west central Axel Heiberg Island in the Canadian High Arctic occur in a region with a mean annual air temperature of -17øC and flow through continuous permafrost over 600 meters thick. The outflowing spring water is a low temperature (up to 6øC) brine that maintains constant discharge temperatures and flow rates throughout the year. Here we report on observations of the thermal regime associated with these springs and develop a combined flow and thermal model of the subsurface flow using the measured geothermal gradient. We also consider the implications these springs have for the search for similar environments, past or present, on Mars.
