Seriously– The sea off Nantucket turned into a giant Slurpee, with waves breaking slowly and silently: spooky! I've seen ice slush in alpine lakes and also in rivers on the point of freezing, but waves?

A photographer captured slushy waves in Massachusetts, a wintry phenomenon that even some glaciologists could not fully explain.

Like something out of Interstellar. Cool. ( no pun intended, LOL )

In rivers, when water is near the freezing point, turbulence (by decreasing pressure/density) will cause crystals of ice to form as if by magic. You can see the water leaving a pool with no ice crystals and then exiting a rapid or riffle dense with frazil ice, which sticks to the bottom, banks, and boulders. Also sticks to waders and drysuits, DAMHIKT.

Anyone who goes out there is a slush puppy!

Ha!

I observed (putting it mildly) another curious phenomenon while skiing across frozen lakes at high elevation, where cracks in the ice allow water to rise and form pools under the surface snowpack. Since the water is right at the freezing point, the turbulence of a ski plunging in and out of the pool causes ice to form, and a few steps on, your ski and boot are armored with an inch of ice (and suddenly very heavy).

News report, more photos but no video of the waves, alas!
