Jaatunnukset

Jaatunnukset, also known as icebergs, are large masses of ice that break off from glaciers or ice shelves and float in the ocean. They are a significant feature of the polar regions and play a crucial role in the global climate system. Icebergs are primarily composed of freshwater, which is why they float on the ocean's surface. The term "jaatunnukset" is Finnish for icebergs, reflecting the language's use of compound words to describe natural phenomena.

The formation of icebergs occurs when chunks of ice break off from glaciers or ice shelves due to natural processes such as calving or melting. These ice masses can vary greatly in size, with some being as small as a few meters across, while others can extend for kilometers. The largest iceberg ever recorded was Iceberg B-15, which measured 295 kilometers in length and 37 kilometers in width.

Icebergs are a vital component of the Earth's cryosphere and have a significant impact on ocean currents and marine ecosystems. They also pose a hazard to maritime navigation, as their submerged portions can be dangerous to ships. Despite their potential dangers, icebergs are a fascinating natural phenomenon that continues to be studied by scientists and researchers.
