Scientists have finally unraveled the mystery of mystical underwater rings in the Baltic Sea. As it turned out, toxins are to blame. But let's go back to the beginning of the story and remember how it all happened.
In 2008, a tourist who arrived on the Isle of Mont inDenmark, noticed strange patterns in shallow water near the chalk cliffs. As seen in the image above, the patterns took the form of circles. Some of them reached 15 meters in diameter.
The media put forward different versions: starting from the bombings of the Second World War bombing and ending with alien tricks.
Scientists joined the case. After a detailed study of biologists found that the mysterious circles are the result of the unusual location of the sea seabed. Perennial sea grass with long narrow leaves grows around the perimeter, forming a ring. Since Zostera belongs to meadow formations, this direction of grass growth has caused a number of questions.
Biologists Marianna Golmer of the University of the SouthDenmark and Jens Borum of the University of Copenhagen found that the rings are due to the accumulation of sulfide in the mud around the grass. Toxic to sea grass sulphide destroys thickets in the center of the rings, but does not touch it around the perimeter.
Most of the clay in this part of the Baltic Sea is quickly washed out, but some is delayed by thickets of sea grass.
Silt clay is preserved only inside the circle, it is here that the plants are subjected to poisoning, the Los Angeles Times quoted the words of Danish scientists as saying.
The mystery of the sea rings has been unraveled, but the mysterious Martian stone has yet to be studied.
