young ice
A technical term used in sea-ice classification; refers to ice in the transition stage between nilas and first-year ice, typically 5–20 cm thick.
Young ice is positioned between nilas and first-year ice in sea-ice classification.
Nilas is a thinner, darker, and more elastic ice type that forms before young ice.
First-year ice is thicker and more developed than young ice, having survived at least one summer melt season.
Compound of 板状 (board-shaped, plate-like) + 軟氷 (soft ice), describing the flat, flexible nature of young ice.
