Cj. Merry et Im. Whillans, ICE-FLOW FEATURES ON ICE STREAM-B, ANTARCTICA, REVEALED BY SPOT HRV IMAGERY, Journal of Glaciology, 39(133), 1993, pp. 515-527
Numerous features of glaciological significance appear on two adjoinin
g SPOT High Resolution Visible (HRV) images that cover the onset regio
n of Ice Stream B, Antarctica. Many small-scale features, such as crev
asses and drift plumes, have been observed in aerial photography. Subt
le large-scale features, such as long flow traces that have not been m
apped previously, are clear in the satellite imagery. Newly discovered
features include ladder-like runners and rungs within certain shear m
argins, flow traces that are parallel to ice flow, unusual crevasse pa
tterns and flow traces originating within shear margins.
