Estimating the Salinity of Subglacial Lakes From Existing Aerogeophysical Data
Entry ID:
creyts_0636584
Summary
Abstract:
This award supports a project to estimate the salinity of subglacial Lake Vostok, Lake Concordia and the 90 deg.E lake using existing airborne ice-penetrating radar and laser altimeter data.
A change in personnel during the course of the grant moved the direction toward dynamic drainage and water flow beneath glaciers and ice sheets with particular emphasis on the interior of Antarctica and overdeepenings. Purpose: These lakes have been selected because of the availability of modern aerogeophysical data and because they are large enough for the floating ice to be unaffected by boundary stresses near the grounding lines. The proposed approach is based on the assumption that the ice sheet above large subglacial lakes is in hydrostatic equilibrium and the density and subsequently salinity of the lake's water ...
