Despite regular discoveries about the ocean and its denizens, much remains unknown. The depth of this point is estimated to be 10,994 meters. Geologically, an ocean is an area of oceanic crust covered by water. Yet for all of our reliance on the ocean, more than eighty percent of this vast, underwater realm remains unmapped, unobserved, and unexplored. The ocean is the largest unexplored place on Earth—less than 5 percent of it has been explored. Ocean exploration relies on teams of science researchers across the globe. Most of the ocean is unexplored — about 95 percent of this underwater realm is unseen by human eyes. An untold number of shipwrecks and air wrecks lay on the floor of the ocean, out of sight and out of reach. With this in mind, we explain why a body of water that covers most of Earth’s surface is also one of the most vulnerable – and least understood – places in the universe.
We’re often told that we know more about the surface of Mars / the Moon / Venus (delete at whim) than the depths of the ocean, and that 95 percent of the ocean is “unexplored”. As of the year 2000, the National Oceanic and Atmospheric Administration (NOAA) estimated that as much as 95 percent of the world's oceans and 99 percent of the ocean floor are unexplored.
The entire ocean floor has been mapped, but only to a resolution of 5 kilometers 3 miles. And because it’s difficult to protect what we don’t know, only about 7% of the world’s oceans are designated as marine protected areas (MPAs). In fact, the entire ocean floor has been mapped to a maximum resolution of approximately 5 km which means that all features on the ocean floor that are larger than 5 km across have been mapped.
More than 80% of the ocean remains unexplored. The deepest part of the ocean is nearly seven-and-a-half miles down. But in the ocean, life is found all the way from the surface to the very bottom of the deepest part. A global image of many underwater features larger than 10 kilometres (6.2 miles) was created in 1995 based on gravitational distortions of the nearby sea surface. Approximately five percent of the ocean has been discovered, which leaves 95 of the ocean unexplored. Much of the ocean bottom remains unexplored and unmapped. While we have a firm understanding of shallower parts of the sea, there is much we have yet to learn about it. Throughout history, the ocean has been a vital source of sustenance, transport, commerce, growth, and inspiration. The ocean takes up about 71 percent of Earth's space, yet a whopping 95 percent of that ocean is completely unexplored [source: NOAA ]. How much do we know about the oceans? Colossal coral reef The Great Barrier Reef in Australia is the largest living organism on Earth and can be seen from the moon.
But nearly 80% of oceans have gone unexplored.
Because of this, the oceans contain 99 percent of the living space on the planet. 1.8). That makes for a great meme, and there’s a nice infographic out there on social media to illustrate it: Some experts believe that the claim that only 5% of the ocean floor has been mapped, leaving 95% of the ocean floor unmapped, is not completely accurate. This deep, crescent shaped trench was formed by ocean to ocean subduction about millions of years ago. The deepest point in Mariana trench is known as ‘challenger deep’. Most of the ocean is unexplored — about 95 percent of this underwater realm is unseen by human eyes. A region covering 70% of the Earth’s surface, the ocean is as vast as it is mysterious.
