Sorry, no etymologies found.
The initial focus of the melting is a strange phenomenon called cryoconite.
From the cryoconite holes, the surface water drains through a network of much larger sinkholes and crevasses on the ice sheet.
Cryobiosis, the ability to withstand freezing, allows tardigrades to inhabit cryoconite holes.
The cryoconite hole may freeze up again when the winter comes, of course, but its inhabitants can wait in the ice for the sun to come again.
