Term: Second-year ice
Definition: Sea ice which has not melted in the first summer of its existence. By the end of the second winter it attains a thickness of 2 m and more. It stands higher out of the water than first-year ice. Summer melting has somewhat smoothed and rounded the hummocks, while accentuation of minor relief by differential melting may have caused others to develop. Bare patches and puddles are usually greenish-blue.
