Term: Second-year ice
Definition: Sea ice terminology. Describes old ice which has survived only one summer's melt. Thicker than first-year ice, it stands higher out of the water. In contrast to multi-year ice, summer melting of second-year ice produces a regular pattern of numerous small puddles. In this case, bare patches and puddles are usually greenish-blue.
