an ice shelf is born. Meteoric ice floats on sea water because of its density being smaller (910 kilograms per cubic meter) compared to the density of sea water (1028 kilograms per cubic meter). An ice [...] part of an ice sheet and floats on the ocean, but it rests on the sea floor at its fringes and on embedded islands. Contact with the sea floor slows down the seaward movement of shelf ice and thus the ice [...] formed by intensive sea ice formation in coastal polynyas (large ice-free area near the coast) flushes the ice shelf cavity (Fig. 2), causing melt rates less than 1 meter per year.
