Ice Engineering - A Heat Sink Method for Subsurface Ice Thickening.
Ice sheets are being used as runways and as roadbeds for aircraft and heavy-haul transportation vehicles in the Arctic and Antarctic. Thin ice often makes operations on the ice sheets costly and dangerous. The Civil Engineering Laboratory has developed methods of freezing seawater at coastal polar l...
