A seismic transect was collected between the Morris Jesup Rise and the Yermak Plateau. The seismic data reveal a sedimentary cover that is thin relative to the age of the oceanic crust at 83°N, 10°E and 85°N, 15°W. Close to the plateaus, thicker sequences are evident. The seismic lines on the Morris Jesup Rise reveal only a thin sedimentary cover of 0.2 s TWT. In contrast, a layer with a thickness of almost 0.9 s TWT (1300 m) was found on the northernmost tip of the Yermak Plateau. The topography of the oceanic basement is very rough along the seismic lines, as could be expected at a slow spreading ridge.
