the dissolved materials are left behind.In this manner,seawater directly beneath freshly formed sea ice has a higher salinity than it did before the ice appeared.Of course,when this ice melts,it will tend to decrease the salinity of the surrounding water.In the Weddell Sea,the densest water ...

Where are bile salts produced? What does a catabolic reaction look like? Are endothermic reactions anabolic or catabolic? What molecule is formed as a result of catabolic processes? Where does reduction occur in an electrolytic cell? Are redox reactions anabolic or catabolic?
A third process by which salinity may be altered is associated with the formation and melting of sea ice.When seawater is frozen,the dissolved materials are left behind.In this manner,seawater directly beneath freshly formed sea ice has a higher salinity than it did before the ice appeared.Of...
