Collaborative Research: Deciphering the Deep Ice and the Ice-water Interface over Lake Vostok Using Existing Radar Data
Entry ID: creyts_0537752

Abstract: This award supports a project to evaluate radio-echo intensities in the available SOAR ice-penetrating radar data along grids covering Lake Vostok, and along four regional tracks from Ridge B toward the lake. The project has two objectives; first, it will examine the upper surface of the lake and reflectors hypothesized to be a boundary between the meteoric and accreted ice. They will provide ...

Purpose: Findings:

We have investigated the hypothesis that the meteoric–accreted ice boundary
is visible as a weak reflector in the radar data. Using ice-core and borehole-temperature
data, we seek possible reflection causes that explain the radar-derived
reflectivity (~48 dB). Ice-core data show large variations in the number
density of inclusions, soluble chloride-ion concentration ([Cl]),
