Drift ice, also called brash ice, is sea ice that is not attached to the shoreline or any other fixed object (shoals, grounded icebergs, etc.). [1] [2] [3] Unlike fast ice, which is "fastened" to a fixed object, drift ice is carried along by winds and sea currents, hence its name.

Polynyas may contain brash ice and/or be covered with new ice, nilas, or young ice; submariners refer to these as SKYLIGHTS. Sometimes the POLYNYA is limited on one side by the coast and is called a SHORE POLYNYA or by fast ice and is called a FLAW POLYNYA.

Jan 1, 2014 · Accumulation of floating ice made up of fragments less than about 2 m across is called brash ice. Brash ice often forms between the ice floes. Brash ice consists of frazil ice that grows during freeze-up as well as rudiments of fracturing and colliding floes.

Jun 9, 2020 · Brash Ice is the ‘wreckage’ of other sea ice, smaller pieces of sea ice that have broken off and are not more than 2m across. When drift and brash ice are driven together by wind and currents it creates Pack Ice. This is ice that quickly forms and remains attached to the shore, or to an ice front such as an ice wall, shoals, or iceberg.

Any break or rupture through very close pack ice, compact pack ice, consolidated pack ice, fast ice, or a single floe resulting from deformation processes. Fractures may contain brash ice and/or be covered with nilas and/or young ice.

Apr 1, 2021 · This article details experimental work investigating model brash ice properties, scrutinizes links between the brash ice properties and the vessel resistance in brash ice, providing fundamental basic understanding and the basis for further research.

Brash ice is an accumulation of floating ice made up of fragments not more than 2 m across. It is the wreckage of other forms of ice. Brash is common between colliding floes or in regions where pressure ridges have collapsed.

Brash Ice: Accumulation of floating ice made up of fragments not more than 2 m across, the wreckage of other forms of ice. Ice Cake: Any relatively flat piece of ice less than 20 m across. Floe: Any relatively flat piece of ice 20 m or more across.

Jammed Brash Barrier: A strip or narrow belt of new, young or brash ice usually 100-5000 metres across formed at the edge of either floating or fast ice or at the shore. Heavily compacted, mostly due to wind action, may extend 2 to 20 metres below the surface, but does not normally have appreciable topography.

accumulation of floating ice made up of fragments not more than 2 meters (6.6 feet) across, the wreckage of other forms of ice.
