Abstract
One method of thickening an ice sheet is "free flooding": ice is built up by successive flooding and freezing of sea water layers. The salinity of the built-up ice is of great interest because it plays an important role in establishing mechanical properties. Detailed observations on salinity of flooded water and built-up ice were carried out during construction of an ice platform. Ice salinity was generally about 20% which is significantly lower than the salinity of the original sea water (approximately 30%). Almost half of the "lost salts" disappeared during the freezing period of a layer; the remainder were lost during subsequent floodings. Detailed salinity, thin section and dye migration measurements were used to postulate processes of horizontal as well as vertical desalination during construction of the ice platform.
