Description
Dag Ottesen and three colleagues published a geology study in two thousand twenty-four on the glacial past of the North Sea. How often ice sheets covered the central basin has long been disputed. Old readings claimed several early advances.
Detailed 3D seismic images showed landforms and sediments under the seabed at fine scale. A single ground-ice advance from Norway during the Early Pleistocene appears in the record, probably about one point one million years ago. It left till up to one hundred twenty metres thick across over ten thousand square kilometres. The rest of the period shows seabed pockmarks and current-carved grooves, not ice. The findings reconcile sea and land evidence for northwest Europe.
