When you enter really cold water such as a river, lake or ocean, you start by testing how cold the water is, not by plunging into the water.
When the ocean water freezes, it increases the salinity. When the ocean water freezes at the surface, ice will float on top of water because ice is less dense than liquid water. The dissolved solids are squeezed out of the ice and enter the liquid water below the ice. This increases the salinity of the water. The density of the water also increases.
