  1. Bea CsathoPlanned IceBridge Team Member Activity Contributions to OIB: • Determining the evolving topography of Greenland and Antarctic Ice Sheets, a collaboration with NSIDC (T. Scambos and B. Raup) • Generation of baseline DEMs from altimetry data, photoclinometry and stereo imagery • Deriving dh/dt data sets from fused altimetry data sets and creating evolving multiresolution DEMs, updated once or twice every year, by using Surface Elevation Reconstruction And Change detection (SERAC) software (Schenk/Csatho) and NSIDC software (being developed) • Geostatistical and wavelet analysis of elevation and dh/dt data to derive surface characteristics, characterize errors and uncertainties. • Improved calibration of satellite derived temperature data of Greenland and Antarctica (MODIS, AVHRR), collaboration with J. Comiso (NASA/GSFC), contribution to determination of firn compaction and surface mass balance to facilitate the interpretation of ice sheet elevation changes • Digital Stereo Mapping (DSM) for IceBridge, including error characterization of DSM data from 2009 Antarctic IceBridge mission, fusion of altimetry and stereo data and design of a convergent camera system for high altitude mapping (“LVIS gapfiller”) Utilizing OIB data for my research: • Detailed studies of key Greenland outlet glaciers, collaboration with J. Briner (UB), C.J. van der Veen and L. Stearns (U. of Kansas) and J. Johnson (U. Montana), K. Kjaer (U. of Copenhagen) and A. Khan (Danish Space Research) • Creation of long-term records from from exposure dating, glacial geology, historical observations, GPS and combine them with airborne and satellite observations (ICESat, ATM, ASTER, etc.) from the last decades • Force balance studies for estimating driving stresses and their evolution • Comparison of observations (elevation and velocity changes, etc.,) with model outputs, e.g., from Comsol multiphysics, Community Ice Sheet Model (CISM) to understand processes and predict future behavior UB Team: B. Csatho (OIB Team member), T. Schenk (Research Professor), S. Nagarajan (postdoc), G. Babonis (PhD student, NASA, ESSF), S. Rezvan-Behbahani (MS Student)
