1. What is the location?Cold ocean waters and freshwater lakes
2. What is the scientific classification?Natural phenomenon, not a species
3. What is shuga ice?Shuga is a spongy, porridgy ice that floats in water. It is made of many small ice crystals suspended in liquid, forming little lumps a few centimeters long.
4. How does shuga form?Shuga starts from grease ice or anchor ice. Wind and waves break the ice into small lumps, creating a semi‑fluid, spongy texture.

Frazil ice: Microscopic ice crystals that form in turbulent, supercooled water, the initial stage of ice formation.
Grease ice: A soupy, viscous layer of ice formed from coalesced frazil ice crystals on the water surface.
Anchor ice: Ice that forms on the bottom of a body of water, often attached to submerged objects.
Albedo: The measure of how much light that hits a surface is reflected without being absorbed; ice has a high albedo.
