“…The interfingering of high-Ca •+ groundwater to its appropriate density level can produce layers of very different Ca•+/Na + in a lake. See, for example, the data of Bell [1967] for Lake Miers. Layers of high Ca•+/Na + ratio presumably contributed by groundwater can be seen at 17 m below the surface and at the bottom.…”

Although much of the Antarctic continent is covered with ice and snow, there are some small areas which are ice free. This paper reviews the lake physics and geochemistry of these dry areas. The Antarctic dry areas represent a climatic region not found elsewhere in the world. Because of the extreme cold and aridity and the fact that these areas are truly rainless, many features and phenomena exist that are not found on the other continents. The major source of the salts in the soil and lakes appears to be from the sea via snow. A relative humidity mechanism for salt separation is proposed in order to explain the distribution of salts in the soils, glaciers, streams, and lakes of Antarctic dry areas. This mechanism leaves the least deliquescent salts in the soil and delivers the more deliquescent salts to the groundwater which flows along the surface of the ice-cemented layer and hence to the saline lakes. While in the groundwater system, trace elements such as strontium may be leached from the soils. Climatic conditions are such that perennially ice-covered freshwater lakes can exist, and the conditions for the existence of these are defined. Solar heating of density-stratified lakes is common and in some cases very spectacular, the bottom of Lake Vanda being 46øC above the mean temperature of the region.

“…A thick ice cover would effectively isolate the water column from summer sunlight and elevated spring temperatures would not be expected, because they are not observed in Antarctic lakes that maintain similar temperatures year-round. Lake Miers, Antarctica, is a perennially ice-covered lake similar to Colour Lake in area and depth and has a similar thermal and chemical profile (including a 2-m anaerobic layer) (Bell 1969) to the 25 May 1990 profile of Colour Lake. Bell (1969) accounted for the Miers temperature profile as being almost entirely an artifact of solar heating.…”

A discontinuous ice coverage and lake temperature record of 36-yr duration has been compiled for Colour Lake (79"25'N, 90"45'W) on Axe1 Heiberg Island, Northwest Territories. About once every 6 yr, the ice cover remains through the entire summer, creating a residual ice cover the following winter. Residual ice covers are more frequent in the last 10 yr (1986)(1987)(1988)(1989)(1990)(1991)(1992)(1993)(1994)(1995) than in the 20 yr from 1959 to 1978, indicating a reduction in climate factors controlling ice decay. These factors are identified as the number of thawing degree-days, suggesting a tendency toward cooler summers over the last decade. We report year-round meteorology observations that indicate a mean annual temperature of about -15.2"C, with -500 thawing degree-days in summer. Following a residual ice year, spring lake-water temperatures are significantly greater than they are following nonresidual years. The increased temperatures can be attributed to the stabilizing effect of the residual ice pan the previous fall. Without an ice pan, convection cools the entire water column before the surface freezes. When the lake has an ice pan at the start of freezing, the surface freezes over quickly, effectively trapping water heated during summer. The warmer spring water temperatures act as negative feedback, decreasing the potential for a second consecutive residual ice year.
