A strip or narrow belt of new, young or brash ice (usually 100-5000 m wide) formed at the edge of either drift or fast ice or at the shore. It is heavily compacted mostly due to wind action and may extend 2 to 20 m below the surface but does not normally have appreciable topography. Jammed brash barriers may disperse with changing winds but can also consolidate to form a strip of unusually thick ice in comparison with the surrounding drift ice. This is also known as a windrow in the Baltic Sea.
