How Much Of The Ocean Has Been Discovered By Humans

And of course actually to see the seafloor using cameras or our own eyes means getting even closer using tools such as remotely operated vehicles or manned submersibles. The entire ocean floor has been mapped but only to a resolution of 5 kilometers 3 miles.

Yet much about the planets oceans remains a mystery.

How much of the ocean has been discovered by humans. The oceans account for 70 percent of Earths surface. American undersea explorer Victor Vescovo has become the first person to dive to the deepest points of the earths five oceans and hes now back on dry land to reveal his discoveries. Just 5 percent of Earths oceans have been explored and charted especially the ocean below the surface.

Less than 20 has been mapped at a resolution finer than 100 meters still pretty coarse but there are vast areas of ocean that have less than one depth sounding per 100 square km. However that number is a bit misleading. What percenatage of the ocean have we discovered on earth.

More than 80 of the ocean remains unexplored. That means that we can see any features larger than 5 kilometers. Since the beginning of the Industrial Revolution the acidity of surface ocean waters has increased by about 30.

Scientists estimate that 91 percent of ocean species have yet to be classified and that more than eighty percent of our ocean is unmapped unobserved and unexplored. Yet one of the last unknown frontiers and one of the most deceptively familiar is on our very own planet. The ocean bottom is somewhat less well explored but there is little room left for any big surprises.

That doesnt seem like it could be true. 13 14 This increase is the result of humans emitting more carbon dioxide into the atmosphere and hence more being absorbed into the ocean. And because its difficult to protect what we dont know only about 7 of the worlds.

The ocean takes up about 71 percent of Earths space yet a whopping 95 percent of that ocean is completely unexplored source. An estimated 50-80 of all life on earth is found under the ocean surface and the oceans contain 99 of the living space on the planet. The ocean has absorbed between 20 and 30 of total anthropogenic carbon dioxide emissions in recent decades 72 to 108 billion metric.

Less than 10 of that space has been explored by humans. In 1960 Jacques Piccard and Don Walsh descended 36000 feet to the bottom of the Challenger Deep in the Mariana Trench the deepest place in the ocean. So far less than 005 of the ocean floor has been mapped to that highest level of detail by sonar which is an area roughly equivalent in size to.

While these statistics may sound daunting they have not stopped the global scientific community from striving to amass as much knowledge as possible about ocean life. The rest remains mostly undiscovered and unseen by humans. At present less than 005 percent of the ocean floor has been mapped to that highest level of detail by sonar which is an area roughly equivalent in size to Tasmania.

But if you define explored to mean have we taken a photograph and possibly a sample of what life and geology exists then the answer is far less than 1 of the ocean has been explored. As of the year 2000 the National Oceanic and Atmospheric Administration NOAA estimated that. Despite the long history of underwater exploration approximately eighty percent of our global ocean remains unmapped and unexplored.

We currently know where 100 of the worlds oceans are.
