Investigator, Investigator Malayalam presenting new video about Top 4 Deep Unexplained Sea Mysteries That Will Freak You Out in Malayalam language in this video we are mainly looking Before you get in the water this summer, remember there's a lot going on under the sea we don't yet know about.Seventy percent of the Earth’s surface is below the ocean, yet 95 percent of it remains unexplored to the human eye. Although the oft-heard statistic is that we know more about the surface of Mars than we do about the ocean seabed, scientists have been able to map the entire ocean floor—but the resolution is incredibly poor, so we can only visualize features larger than three miles. Ongoing research like Seabed 2030 aims to bring the ocean floor into greater focus, so we can better see and understand what’s really down there. For now, we can just marvel at the most stunning deep-sea sights in the world.
For hundreds of years, sailors have reported randomly encountering a strange “milky” cast to the sea as far as the eye can see, but scientists have been unable to explain it—or even know for sure if it was real. In 2006, researchers were actually able to capture a satellite image of a milky sea, and several years later, experiments discovered the glow was likely from bioluminescent bacteria that attract fish in order to be eaten and survive in their guts. But, scientists still aren’t sure how or why the bacteria gather in such huge numbers as to be able to be seen from space. In addition, their glow is continuous, unlike the more commonly seen “dinoflagellate” organisms that produce brief flashes of light.
In 2016, researchers from Ocean Exploration Trust (founded by oceanographer and Titanic discoverer Robert Ballard) aboard the Exploration Vessel Nautilus found a strange purple blob on the ocean floor off California. Stumped as to what it could be, the scientists joked about it being a spider egg sac or a “tiny momma octopus,” and nicknamed it Blobus purpilis before battling with a crab to retrieve the specimen. It looks kind of like a strange and mesmerizing jellyfish. Research is ongoing as to what the orb is, but it’s hypothesized to be a new species of velutinids, a type of snails. Here are more of the most stunningly beautiful underwater photos ever taken.
Could there be an alien spaceship on the ocean floor? In 2011, ocean explorers found an oval-shaped object with strange markings on the bottom of the Baltic Sea. The resulting “images”—which were really created by a graphic artist—of the otherworldly discovery quickly made the rounds on the Internet (the only real visualization is a grainy sonar image). Scientists think the anomaly is actually a glacial deposit or some other natural formation, but its origins are uncertain pending further exploration. Who knows? Of course, whether intelligent alien life exists at all is one of the biggest unsolved mysteries about the universe.
This huge animal could be the mythical kraken featured in Pirates of the Caribbean and Jules Verne’s 20,000 Leagues Under the Sea. Although it’s unlikely that the giant squid actually attacked ships, very little is known about this mysterious creature of the deep. It wasn’t even photographed alive until 2004 and not filmed until several years later, when it was caught at the surface. Underwater video was not accomplished until 2012. Scientists have learned virtually nothing about the lives of these deep-sea giants, not even how big they get, although some estimates predict they grow up to 66 feet. Only their cousin the colossal squid might be bigger in weight, although probably not length—but even less is known about them. In real life, many sea creatures are adorable, rather than horrifying; these photos of manatees prove it.
We might not know much about the terrain of the ocean, but we have seen is just as stunning as what’s on land—and in fact, may be strikingly similar. “Brine pools,” where the salt water concentration is greater than the surrounding ocean, create lake-like surfaces and shorelines. Earth’s largest waterfall is actually underwater in the Denmark Strait, where colder water tumbles over a huge drop in the ocean floor, falling 11,500 feet (the largest land waterfall is only 3,212 feet). Underwater volcanoes erupt—the largest one ever recently happened, and scientists almost missed it. Although researchers know all of these things exist, their exact mechanisms are still being investigated, making them one of the perplexing science mysteries no one has figured out.
