Brine rejection that drains from the newly formed ice is replaced by a weak flow of relatively fresh water, from the liquid region below it. The new water partially freezes within the pores of the ice, increasing the solidity of the ice. As sea ice ages and thickens, the initial salinity of the ice decreases due to the rejection of brine over time [Fig. 2]. While the sea ice ages, desalinization occurs to such a degree that some multiyear ice has a salinity of less than 1 PSU. This occurs in three different ways: Brine rejection occurs in the sea ice packs
Salt well Salt well A salt well (or brine well) is used to mine salt from subterranean caverns or deposits. Water is used as a solution to dissolve the salt or halite deposits so that they can be extracted by pipe to an evaporation process, which results in a brine or dry product for sale or use. In the United States during the 19th century, salt wells were a significant source of income for operators and the government. Locating underground salt deposits was usually based on locations of existing salt springs. In mountainous areas, a similar technique called sink works (from German
