The ice begins to thicken and pancakes form
 - Sea Ice

#The ice near to the shore here is known as "pancake-ice". This is formed when slabs of ice that are forming are jostled by the wind and / or movement of the sea. The pancakes of ice bash against each other around the edges and start to curl upwards at the edges.

"Pancakes of submerged ice joined with others into great sheets, the rubbery green ice thickened, an ice foot fastened onto the shore, binding the sea with the land. Liquid became solid, solid was buried under crystals."
