A PRELIMINARY SUBSURFACE HEAT TRANSFER STUDY OF THICKENING SEA ICE.
Any method of accelerating the growth of an ice sheet results in thicker and, in most cases, stronger ice. To eliminate the problems of excessive salt and a temporary isothermal temperature gradient associated with surface flooding, three methods of accelerating bottom freezing of an ice sheet were...

Any method of accelerating the growth of an ice sheet results in thicker and, in most cases, stronger ice. To eliminate the problems of excessive salt and a temporary isothermal temperature gradient associated with surface flooding, three methods of accelerating bottom freezing of an ice sheet were investigated.
