Frazil ice consists of small suspended ice crystals formed in supercooled turbulent water. A layer of crystals can damp surface gravity waves through viscous dissipation, even when individual crystals scatter very little wave energy.

Frazil ice is a type of ice that forms in water under specific conditions, typically in cold environments. It consists of small, loose crystals that form in supercooled water, usually in rivers and oceans, when the temperature of the water is below freezing but the water itself remains in a liquid state. Frazil ice typically forms when turbulent water is cooled rapidly, causing tiny ice crystals to develop and remain suspended in the water.
