Is space the final frontier, or is the human brain? Arguments could be made for either, but there’s a whole lot of evidence that we don’t know much about the ocean. Which makes it a serious contender for “the biggest mystery holder” out there.
Here are 9 of those oceanic mysteries.
Cuba’s underwater city
Deep in the waters off Cuba’s coast, researchers discovered unusual formations of smooth blocks, crests, and geometric shapes. The Canadian exploration company that discovered the formations, Advanced Digital Communications, has suggested that they could be the buildings and monuments of an early, unknown American civilization.
90% of the ocean floors remain unmapped
Gulp. What could be down there?
Although there’s no sunlight at the bottom of the ocean depths, some bacteria are able to photosynthesize and produce food for themselves. Scientists are still trying to figure out how that’s possible.
The Bermuda Triangle
The Bermuda Triangle, also known as the Devil’s Triangle, is a region in the western part of the North Atlantic Ocean, where a number of aircraft and ships are said to have disappeared under mysterious circumstances.
There are some really huge creatures lurking down there.
Like, even bigger than this 515-pound halibut that was just caught by a German fisherman.
Also called underwater tornadoes, in certain conditions they can break away and swirl around like flying saucers across the ocean.
Milky sea phenomenon
Milky seas are a condition on theoceanwhere large areas ofseawater(up to 6,000 sq mi or 16,000 km2) are filled withbioluminescentbacteriaordinoflagellates, causing the ocean to uniformly glow an eerie blue at night. The condition has been present inmariner’s tales for centuries – notably appearing in chapter 23 ofJules Verne’sTwenty Thousand Leagues Under the Sea– but until recently it has not been rigorously documented.
Lost submarines of 1968
The year 1968 saw the still-unexplained loss of submarines by four countries: the United States, Russia, Israel, and France. Some say the losses could have been government cover-ups or (at least in the U.S. case) the nuclear-tipped torpedoes misfiring into the vessel.
Two-thirds of marine species remain unknown
Wow, that’s a lot of unknown creatures.
