Modeling the climatic sensitivity of the inception of the Fennoscandian Ice Sheet
Understanding the sensitivity of ice sheets to climate forcing is crucial for predicting future behavior of ice sheets. Multiple studies have analyzed the inception of the Quaternary ice sheets using time-dependent global climate models. The results have indicated that although carbon dioxide …

The Quaternary evolution of the mid-Norwegian continental margin
… number of cross-shelf troughs produced by past ice streams that periodically drained the growing and decaying Fennoscandian Ice Sheet since approximately 1.5 M.y. ago. The development and intensification of focused ice flow from about 0.8 M.y. ago resulted in enhanced erosion on the shelf and …

Seafloor ploughmarks on the mid-Norwegian continental shelf reveal iceberg trajectories during the last glacial period
… linear to curvilinear depressions interpreted as iceberg ploughmarks were mapped across the mid-Norwegian continental shelf using high-resolution swath bathymetry data. The orientation and morphology of each iceberg ploughmark was calculated and analysed, with features being up to 30 km long and …

Wobbly winds in an ice age : the mutual interaction between the great continental ice sheets and atmospheric stationary waves
The ice sheets of the last glacial maximum (about 21 thousand years ago) covered a significant fraction of the high latitude land mass, reached up to 3km in height, and had length scales of thousands of kilometers. They represented significant obstacles to the westerly flow of the atmosphere. As …
