Geodetic observation and interpretation of ice flow velocities in the southern part of subglacial Lake Vostok / A. Richter, and 8 others.
Title: | Geodetic observation and interpretation of ice flow velocities in the southern part of subglacial Lake Vostok / A. Richter, and 8 others. |
Author(s): | Richter, A. |
Date: | 2012. |
Language: | Russian transliteration entered into original records using BGN/PCGN 1947 romanisation of Russian; Cyrillic text in MARC 880 field(s) reverse transliterated from this by automated process; BGN/PCGN 1947 text then upgraded to Library of Congress romanisation. |
In: | Led i Sneg. (2012.), Vol. 4(120) (2012) |
Abstract: | Combines results of geodetic in-situ observations of ice-flow velocities in southern part of sub-glacial Lake Vostok with data sets of ice surface topography, ice thickness, surface accumulation, basal accretion and firn/ice density to interpret glaciological setting of Lake Vostok system. Describes mean surface accumulation rates for segments extending from southern Lake Vostok to Ridge B ice divide which suggest that area has been close to steady state. Analysis of ice flow dynamics along flow line segment extending from 26 km upstream to 12 km downstream of Vostok station suggests deficiencies in current modelling approaches within transition zone from floating to grounded ice. |
