    • Mobile, nonpermanent, artificial islands and a method of utilizing the same to control the movement of natural ice formations in or near natural and man-made bodies of water such as lakes, rivers, sounds, straits, bays, shipping channels, harbors and the like. The artificial islands are formed from structures having body cavities which are substantially filled with a liquid composition which freezes to form an ice-like solid at a temperature higher than the freezing temperature of the body of water in which they are positioned, thus rigidizing and firmly securing the structures to the bed of the body of water prior to the formation of natural ice in the body of water. During warm seasons the liquid composition melts allowing the artificial islands to be easily transferred to new positions, thus optimizing control of ice movement in any specific body of water at minimum cost.
    • 移动,非永久性,人造岛屿及其利用方法来控制天然和人造水体等湖泊,河流,声音,海峡,海湾,航运渠道,港口等天然冰层的运动。 喜欢。 人造岛由具有体腔的结构形成,其体积基本上填充有液体组合物,其在比它们所位于的水体的冷冻温度高的温度下冻结形成冰状固体,因此刚性化并且牢固 在水体中形成天然冰之前将结构固定在水体的床上。 在温暖的季节,液体组合物熔化,允许人造岛容易地转移到新的位置,从而以最小的成本优化对任何特定水体中的冰运动的控制。
