The growth will extend upstream and increase in width until the point where the frazil ice accumulations bridge together and block the water.
12.
The ice cover is composed of juxtaposed frazil ice pans and break-away border ice pieces that consolidate in the river flow direction.
13.
The uppermost layer of the ocean is supercooled to slightly below the freezing point, at which time tiny ice platelets ( frazil ice ) form.
14.
If the level of turbulence is sufficient, the frazil ice will be mixed down into the upper layer and form a surface layer of grease ice.
15.
Frazil ice has also been demonstrated to form beneath temperate ( or " warm-based " ) glaciers as water flows quickly downhill and supercools due to a rapid loss of pressure.
16.
As the crystals grow in number and size, the frazil ice will begin to adhere to objects in the water, especially if the objects themselves are at a temperature below water s freezing point.
17.
Most of the already formed ice continued floating south, driven by the wind, so a cold open water surface was exposed on which new ice formed as frazil ice and pancake ice in the rough seas, producing a giant tongue shape.
18.
The channel allows this as it reduces the risk of frazil ice buildup on most of the Dauphin River and after the extended reach extension of the Emergency Channel is completed, the risk of ice jams along the entire Dauphin River will be reduced.
19.
Essentially, the water level and the weather at the time of freeze-up will impact the way the ice forms ( see frazil ice, for example ), how stable it will be, and how smoothly it can be made for skating.
