Havsisbildning
Havsisbildning refers to the process by which seawater freezes to form sea ice. This phenomenon is crucial in polar regions, particularly the Arctic and Antarctic. When the ocean surface temperature drops below the freezing point of seawater, which is approximately -1.8 degrees Celsius (28.8 degrees Fahrenheit) due to salt content, ice crystals begin to form. These crystals aggregate and thicken, eventually creating a continuous layer of sea ice.
The process is influenced by several factors, including water temperature, salinity, and wind conditions. Brine, a
