Answer:
Ocean satellites, scientific buoys, deep sea submarines, and advanced sonar have only been used in ocean exploration for the last 50+ years. And as this technology improves, scientists have been able to discover more of the oceans and map a greater percentage of the ocean's floors.
Explanation:
Nautical exploration is as old as humans. There were sailors and sea merchants mentioned in the Bible, and maritime travel and commerce was common during the ancient period, as the Romans and Greeks both took to the seas to explore.
And today, we remain committed to sea travel. From the global shipping industry, to luxury yacht charters, hundreds of thousands of nautical miles are covered each day around the world. Yet, despite our oceans being more trafficked than ever, they remain mostly a mystery.
So how much of the ocean has been explored? According to the National Ocean Service, it’s a shockingly small percentage. Just 5 percent of Earth’s oceans have been explored and charted – especially the ocean below the surface. The rest remains mostly undiscovered and unseen by humans.
That doesn’t seem like it could be true. The oceans account for 70 percent of Earth’s surface. In other words, humans haven’t yet explored or discovered about 65 percent of Earth’s surface area. And considering the explorations that have occurred in space over the last decades – detailed imaging of the Moon, Mercury and Mars – it seems space exploration is moving at a faster speed than ocean exploration.
