"A Decade+ of Ice Losses Detailed by Satellite Observations," Christopher A. Shuman, University of Maryland, Baltimore County, Joint Center for Earth Technology at NASA Goddard Space Flight Center. As documented by repeated satellite observations in 2002, the collapse of the Antarctic Peninsula’s Larsen B Ice Shelf was a dramatic illustration of the kinds of changes predicted to occur as climate continues to warm. Additional satellite data analyzed in the subsequent years have quantified both the magnitude and the character of ongoing ice losses from both ice shelf remnants and the glaciers that once sustained the floating ice shelf. The same methods used in several recent papers (DEM differencing and repeat laser altimetry) now are being used to assess ice losses from glaciers on the entire northern Antarctic Peninsula as well as subtler losses from ice shelf areas still restraining large tributary glaciers.
