Once sea ice forms, salts are left out of the ice, a process known as brine exclusion. [28] These two processes produce water that is denser and colder. The water across the northern Atlantic Ocean becomes so dense that it begins to sink down through less salty and less dense water.
The brine-rich water remains liquid, and its increased density causes this water to sink, setting the stage for the creation of a "brinicle". Its outer edges begin accumulating a layer of ice as the surrounding water, cooled by this jet to below its freezing point, ices up in a tubular or finger shape and becomes self-sustaining. The down ...
The water underneath becomes saltier and colder, leading to an increase in density. This parcel of water in the Okhotsk Sea is referred to as dense shelf water (DSW). The saltier and colder a water parcel is, the denser it becomes, causing it to sink below other parcels of water. For this reason, the DSW will begin to sink within the water column.
[1] The process of "icing" beer involves lowering the temperature until ice crystals form. Since ethanol has a much lower freezing point (-114 °C; -173.2 °F) than water (0 °C; 32 °F), when the ice is removed the alcohol concentration of the beer increases. The process is known as fractional freezing or freeze distillation. [2]

A biogeochemical cycle, or more generally a cycle of matter, [1] is the movement and transformation of chemical elements and compounds between living organisms, the atmosphere, and the Earth's crust. Major biogeochemical cycles include the carbon cycle, the nitrogen cycle and the water cycle. In each cycle, the chemical element or molecule is ...

Once nilas has formed, a quite different growth process occurs, in which water freezes on to the bottom of the existing ice sheet, a process called congelation growth. This growth process yields first-year ice. In rough water, fresh sea ice is formed by the cooling of the ocean as heat is lost into the atmosphere.
