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
Brine shrimp For example, "A. franciscana" of the Americas has been widely introduced to places outside its native range and is often able to outcompete local species, such as "A. salina" in the Mediterranean region. Among the highly localized species are "A. urmiana" from Lake Urmia in Iran. Once abundant, the species has drastically declined due to drought, leading to fears that it was almost extinct. However, a second population of this species has recently been discovered in the Koyashskoye Salt Lake at the Crimean Peninsula. "A. monica", the species commonly known as Mono Lake brine shrimp, can be found in Mono
