Toetusisikud

Toetusisikud, also known as "toetusisikud" in Estonian, are a unique and fascinating phenomenon found in the Baltic Sea. These are underwater mounds or hills that rise from the seabed, typically measuring a few meters in height and several tens of meters in diameter. The exact origin of toetusisikud remains a subject of scientific debate, with several theories proposed to explain their formation.

One prominent theory suggests that toetusisikud are the result of gas emissions from the seabed. As methane and other gases bubble up through the sediment, they can create these distinctive mounds. Another theory proposes that they are formed by the accumulation of organic matter, such as dead plants and animals, which over time compact and harden into these underwater structures.

Toetusisikud are often found in areas with high biological productivity, where the accumulation of organic matter is more likely. They can also be associated with cold seeps, where methane and other gases escape from the seabed. These mounds can support unique ecosystems, hosting a variety of marine organisms that have adapted to the specific conditions provided by the toetusisikud.

Despite their intriguing appearance, toetusisikud are not well-studied, and much remains unknown about their formation, composition, and ecological significance. Further research is needed to fully understand these enigmatic underwater features and their role in the marine environment.
