Mysterious Ocean Circles In The Baltic Ocean Explained
The first pictures appeared in 2008, taken by a tourist and showing some strange circular formations in the shallow waters off the famous white cliffs of chalk on the island Møn in Denmark. In 2011, the circles came back, and this time there were so many that they made it to the media.
“It has nothing to do with either bomb craters or landing marks for aliens. Nor with fairies, who in the old days got the blame for similar phenomena on land, the fairy rings in lawns being a well known example”, say biologists Marianne Holmer from University of Southern Denmark and Jens Borum from University of Copenhagen.
The circles of eelgrass can be up to 15 meters in diameter and their rim consists of lush green eelgrass plants. Inside the circle there can be seen only very weak or no eelgrass plants.
“We have studied the mud that accumulates among the eelgrass plants and we can see that the mud contains a substance that is toxic to eelgrass”, explain Holmer and Borum.
The poison is sulfide, a substance that accumulates in the seabed off the island of Møn, because it is very calcareous and iron-deficient.
“Most mud gets washed away from the barren, chalky seabed, but like trees trap soil on an exposed hillside, eelgrass plants trap the mud. And therefore there will be a high concentrations of sulfide-rich mud among the eelgrass plants,” explain the researchers.
Sulfide is toxic enough to weaken the old and new eelgrass plants but not toxic enough to harm adult and strong plants. And since eelgrass spreads radially from the inside out the oldest and weakest plants are located in the center of the growth circle.

The waters off Møn’s chalk cliffs are not the only place where sulfide destroys eelgrass. Sulfide poisoning of eelgrass is a major problem worldwide. Sulfide is often created where oxygen disappears from the seabed. This can happen when the seabed is fed nutrients from agriculture.
Underwater meadows of eelgrass and other seagrasses grow in many parts of the world where they serve as home to a variety of small animals, filter the water and trap carbon and nutrients. But the meadows are threatened in almost all regions of the world, and in several places, including Denmark, researchers and authorities work to prevent seagrasses from disappearing.
Facts about seagrass
The University of Southern Denmark is a partner and coordinator of NOVA GRASS, an international five-year research project focused on the restoration of eelgrass meadows.

“The result is an exceptional circular shape, where only the rim of the circle survives…”
If this were true, then the rims of the circles would be green and the centers blue. So in the absence of a rational explanation the ‘scientists’ just make up contradictory BS? Too arrogant to just admit they don’t know? Am I missing something here?
I assume the photo at the top has just had its contrast and colours altered to make the circles more visible.
Makes sense that it’s the same kind of deal as fairy rings – a plant starts as a dot, grows out in all directions and the oldest part dies, leaving behind soil that lacks the nutrients for new plants to grow. Rinse and repeat and you get an expanding circle.
Just because the explanation does not fit you BS beliefs its fake is that it! Spoken like a true tin foil hatter!
The Baltic is a sea, not an ocean.
Simple mistake some of us Scandinavians make when we translate the word “sø” to English. It can mean lake, sea and ocean. This, however, isn’t a page on linguistics now, is it?
God’s put His coffee cup down a few times!
Fairy rings are created by elecro-magnetic effects in the ground and are most notable in the patterns that mushrooms leave after spores are released and that happens over night.. A similar phenomena can be seen in the stone circles of Africa..
Talking about the ocean floor, can you explain this?
Australia by itself is a mysterious land.
