  • Beschreibung: <jats:title>Abstract</jats:title><jats:p>High-resolution numerical model experiments were carried out along two flowlines in Dronning Maud Land, Antarctica, one flowline passing through the central part of a coastal mountain range and the other along a major continental ice stream (Shirase Glacier). Results showed that ice-sheet behaviour in response to the climatic signal differs locally. Response patterns are different for the inland ice sheet, for the coastal ice sheet and around marginal (subglacial) mountains. Modelled response time series were analyzed by lag-correlation, range and fractal analysis. Local differentiation in ice-sheet response is primarily related to the sensitive interplay between surface accumulation patterns, thermomechanical properties of the ice sheet and bedrock roughness.</jats:p>
