Definition: Sea ice terminology. Describes a strip or narrow belt of new, young or brash ice usually 100 m to 5000 m across, formed at the edge of either floating or fast ice, or at the shore. Heavily compacted, mostly due to wind action, a jammed brash barrier may extend 2 m to 20 m below the surface.  ECCCanada
