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.

Should post in stupid questions bin but what is a dipole?

A Dipole is basically an atmospheric set-up that involves a low pressure system and a high pressure system (Dipole=two poles) opposite from each other, causing very strong winds between them. In the Arctic, most of the time, the high pressure will be above the American side of the Arctic, while the low pressure is on the Siberian side.

I posted an example last week, showing that winds would probably cause the ice to open up in the Laptev.

Also see this Wikipedia entry.

And how do you "like" comments? I see many likes but can't figure it out.

The 'like' system isn't working as it should yet. At the top of every comment there should be a 'like' button net to the 'quote' button, but not everyone is seeing it.
