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
Great Salt Lake nuttallii" A yellow-flowered "Calochortus" was first named as a variety of "C. nuttallii" but was later separated into a new species "C. aureus". This species occurs in Utah today, though apparently no longer on the islands of the Great Salt Lake. Because of the Great Salt Lake's high salinity, it has few fish, but they do occur in Bear River Bay and Farmington Bay when spring runoff brings fresh water into the lake. A few aquatic animals live in the lake's main basin, including centimeter-long brine shrimp "(Artemia franciscana)." Their tiny, hard-walled eggs or cysts (diameter about 200 micrometers) are
