| Summary: | The Lambert Glacier and Amery Ice Shelf system is one of the major east Antarctic drainage basins and is the subject of long term and on-going investigation as part of the Australian Antarctic program. In the region of the grounding zone between the glacier stream and the floating ice shelf, snow which accumulated over tens of thousands of square kilometres of the interior ice sheet is funnelled through a relatively narrow area. The way in which the ice in this region flows is influenced by subglacial topography, ice thickness, internal ice flow properties and the nature of the source area of the ice. The primary aim of this study is to use all available data to describe the morphology and dynamic regime of the lower Lambert Glacier and Amery Ice Shelf, and to provide the best estimate of the present mass balance and spatial distribution of the grounding zone. The available data include radio echo soundings of ice thickness, surface elevation data, ice velocity and surface mass balance measurements from ... |
