1. Retreat pattern and dynamics of glaciers and ice sheets: reconstructions based on meltwater features
Abstract : Glaciers and ice sheets covered extensive areas in the Northern Hemisphere during the last glacial period. Subsequently to the Last Glacial Maximum (LGM), they retreated rapidly and, except for Greenland and some other ice caps and glaciers, they vanished after the last glacial termination. READ MORE

2. Sedimentology and Geomorphology of Glacial Landforms in Southern Sweden : Studying the Landscape of a Melting Ice Sheet
Abstract : Ice sheets are disintegrating due to global warming. One factor controlling ice-sheet behavior is the processes active beneath the ice sheet. In particular, processes connected to glacial meltwater drainage are essential to understand ice-sheets behavior in a warming climate. READ MORE

3. Glacial dynamics and till genesis in hilly terrain : A study in the Tallträsk area, central-northern Sweden
Abstract : This study deals with the influence of topography on glacial dynamics and the genesis of till in an area of moder-ate bedrock relief. An area 25 km west of Lycksele, northern Sweden, was investigated using geomorphological and sedimentological methods. READ MORE

4. Retreat pattern and dynamics of glaciers and ice sheets: reconstructions based on meltwater features
Abstract : The pattern of ice marginal retreat during the last deglaciation has, thus far, most frequently been reconstructed using absolute dating methods and landform record. In reconstructions using landform record, meltwater system has most often been neglected. This is predominantly a consequence of the smaller scale of meltwater features. READ MORE

5. Quantitative controls on the routing of supraglacial meltwater to the bed of glaciers and ice sheets
Abstract : The influence of seasonal influx of supraglacial meltwater on basal water pressures and consequent changes in ice surface velocity has been a focus of research spanning over three decades, particularly focussing on alpine glaciers. Now, with increased recognition for a need to better include glacial hydrology within models of ice dynamics and ice sheet evolution, the ability to predict where and when meltwater is delivered to the subglacial system is paramount, both for understanding the dynamics of alpine glaciers, and of large Arctic ice masses.
