Antarctica / Re: What's new in Antarctica ?

I do not know where to post this, but Wilkins ice sheet is showing signs of getting a drumming short term and there is on top of that that eastern crack inland that could expand quite quickly in my mind....

I wonder about the grey coloured ice free spot in the lower third at the calving front. Is this a place where meltwater from underneath the glacier flows into the sea?

I am not what sure what creates these ice free spots, but will you find them reguarly at the calving front of many glaciers.

As here in Giesecke Isfjord:

This time it was a lake that emptied. See attached gif.

The Antarctic Bedrock data was over 10 times harder to align than Greenland. There are hardly any landmarks, just plain white and with fast ice or ice shelfs you don't even know where the land begins. I had to use huge area images to align islands and then cut it down to individual glaciers. The bedrock resolution is just 1km/px as opposed to 0.15km/px for Greenland data.

New Bedrock overlay page for all of Greenlands major glaciers.
