Cold springs in permafrost on Earth and Mars
occur in a region with a mean annual air temperature of 15C and flow through continuous permafrost 600 m thick. The spring water is a low-temperature (up to 6C) brine that maintains constant discharge temperatures and flow rates throughout the year. Here we report on observations of temperature and...
