Concerning the recent crash one of the TV commentators said that it was

Any truth to this.

No - cold water is less dense than warm water.

That's why ice floats.

Depends on the temperature. Max density of fresh water is about 5 degrees
C. Ice floats because it causes a local aberration in gravity.
