This week's Seafloor Sunday is a multibeam bathymetric image from the Ross Sea, Antarctica, showing grooves on the ocean floor. Combine large icebergs with relatively shallow water and you get a situation where the keels of icebergs can plow into the sediment leaving these marks. Image is approximately 25 km across.

Here is a regional map showing the location of the Ross Sea.
