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
History of Bermuda salt pans for evaporation. Salt Cay and Grand Turk Island became salt colonies in the 1680s. According to Jarvis, "these small, hot, dry, and barren islands" were perfect for salt production since the limestone, absence of fresh water, and limited rain fall combined to make the soil unfertile. Yet, average temperatures in the eighties Fahrenheit and the eastern trade wind facilitated evaporation of sea water into a saturated brine for salt crystallized. Natural ponds were augmented with sluices and causeways. Salt originating from this province was cherished for its "brilliant color, purity, and versatility," according to Jarvis. In 1708, eighteen
