We analyze differences in ICESat elevation estimates at orbital crossover locations to determine short-term rates of elevation change for small regions within the Ross Embayment of the West Antarctic Ice sheet. A linear regression of crossover elevation difference against time difference gives an estimate of the mean elevation-change rate during the ICESat mission to date. We observe prevalent elevation change in the south, with uplift in the upstream end of Kamb Ice Stream at 0.24--0.30 m a-1, and thinning in the parts of Whillans Ice Stream, Mercer Ice Stream, and the adjacent Conway and Engelhardt ice ridges at 0.05--0.18 m a-1. These rates of elevation change are too large to be explained by the 0.02 --0.03 m a-1 formal regression error, by seasonal height variations, or by accumulation- or densification-rate variability, suggesting that they reflect real variations stemming from ice dynamics of the region.
