Our results indicate that ice melts in one place and freezes in another. It is a mechanism by which nutrients can be input to the lake.

This means that (glacial) ice melts, leaves the gas hydrates and sediment in the lake, and then freezes as H2O.

He is so wise, that he goes upon the ice three days before it freezes

Mirrors are ice which do not melt: what melts are those who admire themselves in them.

Once the water comes out it freezes, and that produces copious amounts of ice particles.

The warming ocean comes underneath the ice shelves and melts them from the bottom, and warmer air from the top melts them from the top. So they're thinning and eventually they get to a point where they go poof!
