The dinner plate sized discs can sometimes have a thickness of up to 3.9in, and a diameter of 12 in to 9ft.
Experts believe foam on the water freezes overnight, pushing and bumping against each other to become circular.
The discs may then grow overnight when the temperatures fall again, collecting new foam. During the day, when the discs soften in the sun, particularly around the edges, the rims are built up as the pieces collide in the water.
