Abstract
An ice island is constructed in a marine area having a sheet of natural ice whereby, in a basic embodiment, a lower layer of fresh water ice is made by continually adding fresh water to the ice sheet and letting it freeze until the sheet is on bottom. An impervious insulating layer is put on top of the fresh ice and an upper layer is constructed thereon from sea water or mined ice blocks.
