Baltic sea's 'Underwater Fairy Rings' mystery was revealed

Ring-shaped patterns formed at the bottom of the Baltic Sea, precisely off the coast of the Mon island, Denmark. The rings are formed in between sea plants (eelgrass) - can reach 15 meters in width - can sometimes be clearly visible from the surface of the sea water.

The formation was first spotted tourists in 2008, then 2011. Fueled speculation that usually accompanies the appearance of crop circles in farms. Now, the mystery of the cause of the formation of the unique patterns unfold. As it turned out, had nothing to do with aliens or UFO landing.

Marianne Holmer, a biologists of the University of Southern Denmark and colleagues, Jens Borum from the University of Copenhagen convincing, "circle it has nothing to do with the bomb crater or an alien landing site," so that we have quoted from the Huffington Post, on Monday, February 3, 2014. They presented a full story in the Marine Biology scientific journal.

"Also there is no connection with the fairies, who in the past has always been the accused when a similar phenomenon appears in the mainland. Fairy circle in the grass so well-known example," Holmer and Borum said in a statement.

So, what causes it? The answer is 'poison'.

The biologists concluded, the circles formed by the radiating pattern where eelgrass grows - and die when exposed to toxins. In the mud around eelgrass, scientists detected high levels of sulfide. The substances that can poison the eelgrass can occur naturally in the calcareous seabed as in Mon island. Or, unnatural moment agricultural toxins enter the marine ecosystem.

"Most of mud swept away from the barren, calcareous seabed. However, like trees in the ground to catch a bare hillside, eelgrass trap mud," said Holmer and Borum. "Therefore there is a high concentration of sulfide-rich mud between eelgrass plants."

Although like seaweed, eelgrass is actually a flowering plant. As it grow, it expands outward in all directions, creating a circular colony. Healthy adult eelgrass can survive sulfide exposure in the environment - at the edge of the circle. However, older plants in the heart of the colony die.

"The result is a remarkable circular form, where only plants that survive at the edge of the circle - like a fairy circle on the grass," said Holmer and Borum added. (Wanna see another underwater mysterious circle).

Fairy circle on the ground, for example that meets the desert grasslands of Namibia, Africa - which is famous as 'fairy circles' (Jump to related article).

Hypotheses were emerging, no one suspected was the work of ants or termites, also shut off the gas from the lawn soil. Today appear bright spots, the pattern is likely to arise due to natural causes: the fierce competition in the grass below the soil surface. *** [EKA | FROM VARIOUS SOURCES | HUFFINGTON POST]
