Csatho, B., Ahn, Y., Yoon, T., van der Veen, C.J., Vogel, S., Hamilton, G., Morse, D., Smith, B. and Spikes, V.B. (2005). ICESat measurements reveal complex pattern of elevation changes on Siple Coast ice streams, Antarctica. Geophysical Research Letters 32: doi: 10.1029/2005GL024289. issn: 0094-8276.

We compare ICESat data (2003--2004) to airborne laser altimetry data (1997--98 and 1999--2000) to monitor surface changes over portions of Van der Veen (VdVIS), Whillans (WIS) and Kamb ice streams (KIS) in the Ross Embayment of the West Antarctic Ice Sheet. The spatial pattern of detected surface changes is generally consistent with earlier observations. However, important changes have occurred during the past decade. For example, areas on the VdVIS and WIS, where large thinning was detected by the airborne surveys, are now closer to being in balance. The upper trunk of KIS continues to build up with thickening rates reaching 0.4 m/year. Our results provide new evidence that the overall mass balance of the region is becoming more positive, but a significant spatial variability exists. They also demonstrate the potential of ICESat data for detecting spatial patterns of surface elevation change in Antarctica.
