Strange Seagrass Circles In Croatia Are A Mystery To Experts

I read about this when it first came out, but decided to pass. (It didn't involve any ghosts, witches, vampires etc)  Then I noticed that it was floating around the internet in quite a few places, even The Weather Network published this one, so I figure what the hell.  What do I think? Well, let me put it this way, when I was growing up the phenomena of 'crop circles' started being included in the news and gaining exposure, circles very similar to this, just plain circles in fields at first. Over the years however, the crop circles have become more and more intricately designed and elaborate as more fake crop circles are made with fancier elaborate methods and crop circle making technology. But how are you going to fake extremely large 'seagrass circles'. Just nonchalantly dive to deep depths with your tape measures and start pulling away?

If the phenomena even has experts puzzled, then it could be anything. Energy emanating to specific points from deep inside the earth? Protection aura points? Perhaps it's those esoteric and mysterious 'orb prophecies' attributed to the Croatian King Peter Krešimir IV the Great in various legends since the middle ages? (He is seen HERE holding the orb from the time he uttered his famous words)  Coincidental huge round areas of the yummiest seagrass that fish, crabs, turtles and other creepy-crawlies like to eat? I very much doubt it was aliens or UFO's, and am actually positive it isn't. The thing that is interesting besides the actual circles themselves, is how they almost seem intentionally placed and on purpose, evenly spaced from each other and all the same distance from the shore. I'll just leave it at that. An interesting related archaeology story about a recently found ancient age sunken boat found in Croatia, it is dated Pre-Roman even and most likely belonged to the people who went on to become the ancient Illyrians, before they disappeared too, you can read that Here. Some more related ancient history in regards to Croatia Here and Here.

Mystery Seagrass Circles in Croatia Puzzle Experts



Rijeka, Croatia — You've heard about crop circles, but what about seagrass circles? Aerial photos of the coastline of several islands in Croatia show regular circles of sand amidst a sea of Posidonia oceanica, a seagrass endemic to the Mediterranean.

Biologist Mosor Prvan from the Sunce Association, a Croatian nonprofit environmental organization that first noticed the circles, doesn't have an explanation for the phenomenon. The circles are about 164 feet in diameter and are roughly at the same distance from the islands and from one another.

"We've first seen the circles in aerial photos in 2013 while working on a habitat mapping project at the islands of Unije, Susak and Srakane," Prvan told Mashable.

If you know where to look, the circles are easy to spot on Google Maps. But Prvan and the team from Sunce have dived in these locations to check with their own eyes.

"At first we thought it was some sort of photo manipulation, so we dived at one of the locations, and sure enough, the circles were there. They had a perfect edge, as if someone pulled the Posidonia out with a corkscrew," says Prvan.

A similar case of mysterious seagrass rings in Denmark has been explained by scientists in January 2014 — the rings were a result of a poisonous substance that was killing the seagrass, leaving circular marks.

But this case is different in several ways: The rings are larger and more regular, both in their shape and the pattern in which they appear.

Prvan is sure the phenomenon is antropogenic (manmade). "I don't know the cause, but I think it's manmade. I've contacted several experts on Posidonia, and they've never seen anything like that. I don't think it could be a bacteria or a substance poisonous to the seagrass."

Another solution that comes to mind is illegal dynamite fishing, which can damage the seabed, but Prvan waves it off. "Dynamite leaves smaller, irregular trails. It would take a huge amount of dynamite to cause a 50 meter circle."

And it's not all just a brain-teaser, either — the phenomenon could potentially have serious ramification on the environment. "The Adriatic is one of the most important Posidonia habitat in the Mediterranean," says Prvan.

What's the most probable cause, then?

"If I had to take a wild guess, I'd say military experiments. Posidonia grows slowly, only 2 to 3 centimeters a year, and there's a theory among experts that once you removed a patch of Posidonia like that, it would not grow there again," he said. "Whatever caused this could have happened years ago. So, to determine the cause, the first thing to do would be to find out how old these circles are."
