Abstract:

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 locations to thicken natural ice formations into useful platform foundations. This report documents the process of thickening ice by the use of freezing cells to accelerate ice growth on the underside of an ice sheet. The freezing cell described in this report is driven by density differences liquid above is cooled by the air, and liquid below is warmed by the seawater medium. Author
