IPY: Collaborative Proposal: Constraining the Mass-Balance Deficit of the Amundsen Coast's GlaciersEntry ID: Gogineni_0631994
Abstract: This award supports a project to gather data to better understand the mass balance of the West Antarctic Ice Sheet, in the Pine Island and Thwaites region, through the combination of radar altimetry and surface-based ice-core measurements of accumulation.
Purpose: The results of the field work will provide information on decadal-scale average accumulation extending back through the last century and will help constrain a modeling effort to determine how coastal changes propagate inland, to allow better prediction of future change. Comparison of the basin averaged accumulation with ice discharge determined using Interferometric Synthetic Aperture Radar ... (InSAR) velocity data will provide improved mass-balance estimates. Study of changes in flow speed will produce a record of mass balance over the last three decades. Analysis of the satellite altimeter record in conjunction with annual accumulation estimates also will provide estimates of changes and variability in mass balance.
This data set contains airborne radar data over West Antarctica from the Center for Remote Sensing of Ice Sheets (CReSIS) 2009 Antarctica Twin Otter survey. The radar system is the accumulation radar (600-900 MHz stepped frequency pulse radar) and is designed to produce radar data which can be used to track internal layers in the ice sheet typically to a depth of a couple hundred meters. The dataset contains echograms in PNG and Mathworks MAT formats.
