• Erosional topography is recognized on the upper continental rise between 123°and 134°E off Wilkes Land, East Antarctica. Erosion of the upper continental rise up to roughly 500m is observed on seismic lines and is considered to be caused by down-slope density currents of cold shelf water or by thermohaline induced contour currents of Antarctic bottom water. Development of the abyssal channel systems is another bit of evidence that sediments are swept off the sea floor to create erosional depressions on the upper continental rise off Wilkes Land. Because these eroding currents are only active and effective at the continental margin around Antarctica, erosional depressions of the upper continental rise are responsible for formation of the Antarctic margin type.
