Record #161352:

Are long subglacial bedforms indicative of fast ice flow? / Chris R. Stokes, Chris D. Clark.

Title: Are long subglacial bedforms indicative of fast ice flow? / Chris R. Stokes, Chris D. Clark.
Author(s): Stokes, Chris R.
Clark, Chris D.
Date: 2002.
In: Boreas. (2002.), Vol. 31(3) (2002)
Abstract: Used satellite imagery to map subglacial bedforms associated with unusual bottleneck flow pattern north of Dubawnt Lake, Keewatin, Canada, testing assumption that attenuated drumlins and mega-scale glacial lineations are indicative of fast ice flow. Reviews past theories. Sedimentary characteristics are important, but ice velocity is primary control, not always producing long bedforms, but most likely to. Concludes highly attenuated subglacial bedforms indicate fast ice flow, though fast ice flow may not always produce them. Implies that this may enable identification of many more ice streams, changing view on flow dynamics and stability of former ice sheets.
