| Abstract |
The Southeast Greenland continental shelf, slope and rise are subjected to along- and acrossslope erosional and sedimentary processes. Turbidity currents flow through valley systems downslope and create large channel-levée sequences, orientated perpendicular to the slope. Meanwhile strong ocean currents sweep along the slope and rise and over the shelf, bringing in new sediments from other region, interacting with downslope sediment transport processes or eroding sediment. The different processes prevail at different depths and their imprint has changed over time. Climatic changes (glacial vs. interglacial times), but most likely also tectonic processes have a large effect on where and when which processes dominate. |
