Avomeriteet

Avomeriteet is a Finnish term that translates to "sea ice" in English. It refers to ice that forms on the surface of the sea. The formation of avomeriteet is a natural process that occurs when the temperature of the seawater drops below its freezing point, which is typically around -1.8 degrees Celsius (28.8 degrees Fahrenheit) for typical ocean salinity. Factors influencing its formation and extent include air temperature, wind, salinity, and ocean currents.

The appearance and characteristics of avomeriteet can vary greatly. It can be thin and sheet-like, or it can accumulate into thicker, more complex formations like pack ice or ice floes. In areas with strong currents or waves, the ice may break up, creating brash ice. The Baltic Sea, for example, experiences significant avomeriteet formation during its colder months, impacting shipping and coastal activities. The presence of avomeriteet is crucial for polar ecosystems, providing habitats for various species and influencing oceanographic conditions. Its melting in spring also plays a role in freshwater input and nutrient cycling.
