Dissolved gases in the bottom of liquid lakes of the McMurdo oasis area
Entry ID: K094_1991_1992_NZ_1

Abstract: The lakes in the McMurdo Dry Valleys have a density gradient which in turn prevents the usual vertical convection seen in other lakes. Consequently the basal layers of the lakes remain stagnant. Crustal gases permeate through the permafrost into the deep layers of the lake where they become trapped, and the hydrostatic pressure increases the solubility of these gases. By sampling these layers it ... View entire text
