Climate change: 'Stunning' seafloor ridges record Antarctic retreat

DOWDESWELL ET AL
It's amongst the best ocean-floor imagery obtained anywhere around Antarctica
Scientists are learning just how fast the ice margin of Antarctica can retreat in a warming world.
They've identified features on the seafloor that indicate the ice edge was reversing at rates of up to 50m a day at the end of the last ice age.
That's roughly 10 times faster than what's observed by satellites today.
The discovery is important because it puts realistic constraints on the computer simulations that are used to project future change in the region.
