According to NOAA, as of January 2023: "More than eighty percent of our ocean is unmapped, unobserved, and unexplored." Less than 10% of the ocean, including about 35% of the ocean and coastal waters of the United States, have been mapped in any detail using sonar technology. [ 4 ]
The ocean depths still remain a largely unexplored part of the Earth, and form a relatively undiscovered domain. Scientific deep-sea exploration can be said to have begun when French scientist Pierre-Simon Laplace investigated the average depth of the Atlantic Ocean by observing tidal motions registered on Brazilian and African coasts circa the ...
Nitrate and phosphate have ocean residence times of 10,000 [142] and 69,000 [143] years, respectively, while potassium is a much more abundant ion in the ocean with a residence time of 12 million [144] years. The biological cycling of these elements means that this represents a continuous removal process from the ocean's water column as ...

“The deeper you go into the ocean, the less knowledgeable we are,” marine biologist Dr Steve Ross, who was on the same submersible as Ms Rojas, said before the 2022 expedition.
As the world ocean is the principal component of Earth's hydrosphere, it is integral to life, forms part of the carbon cycle, and influences climate and weather patterns. The World Ocean is the habitat of 230,000 known species, but because much of it is unexplored, the number of species that exist in the ocean is much larger, possibly over two ...
