Second-year ice

Alternative definitions (7), class: vernacular (0)
Term: Second-year ice
Definition: Old ice that has survived only one summer's melt. Because it is thicker and less dense than first-year ice, it stands higher out of the water. In contrast to multiyear ice, summer melting produces a regular pattern of numerous small puddles. Bare patches and puddles are usually greenish-blue.
