Гидротермическая структура и подледниковая дренажная сеть ледника Тавле на Шпицбергене

Title: Гидротермическая структура и подледниковая дренажная сеть ледника Тавле на Шпицбергене
Title, transliterated: Gidrotermicheskai︠a︡ struktura i podlednikovai︠a︡ drenazhnai︠a︡ setʹ lednika Tavle na Shpit︠s︡bergene / I.I. Lavrentʹev, and 3 others.
Translated title: Hydrothermal structure and subglacial drainage pattern of Tavlebreen in Svalbard.
Author(s): Lavrentʹev, I. I.
Date: 2011.
Language: Russian.
In: Led i Sneg. (2011.), Vol. 3(115) (2011)
Abstract: Examines changes in ice mass, extent and meltwater drainage for periods 1936-1990 and 1990-2007, based on radar surveys to determine ice thickness, bed topography and thermal structure, and DEMs. Average thicknesses of glacier and near-bottom temperate ice core are 93 m and 20 m. Glacier terminus recession increased from 2.2 m/a for 1936-1990 to 18.7 m/a for 1990-2007. Compares modelled structure of subglacial drainage system for 1936, 1990 and 2007, using various assumptions regarding subglacial water pressure, with observed positions of moulins and temperate ice layer. Finds that closed minima in hydraulic potential field (corresponding to sites of water concentration at bedrock) increased markedly in number and area from 1990 to 2007.
