Ocean is a body of saline water that composes much of a planet’s hydrosphere. On Earth, an ocean is one of the major conventional divisions of the World Ocean, which covers almost 71% of its surface. These are, in descending order by area, the Pacific, Atlantic, Indian, Southern (Antarctic), and Arctic Oceans. The word sea is often used interchangeably with “ocean” in American English but, strictly speaking, a sea is a body of saline water (generally a division of the world ocean) partly or fully enclosed by land.

Saline water covers approximately 72% of the planet’s surface (~3.6×108 km2) and is customarily divided into several principal oceans and smaller seas, with the ocean covering approximately 71% of Earth’s surface and 90% of the Earth’s biosphere. The ocean contains 97% of Earth’s water, and oceanographers have stated that less than 5% of the World Ocean has been explored. The total volume is approximately 1.35 billion cubic kilometers (320 million cu mi) with an average depth of nearly 3,700 meters (12,100 ft).

As the world ocean is the principal component of Earth’s hydrosphere, it is integral to all known 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 is much larger, possibly over two million. The origin of Earth’s oceans remains unknown; oceans are thought to have formed in the Hadean period and may have been the impetus for the emergence of life. — Wikipedia

Ocean (Wolfram Alpha)

Science

Oceanography, also known as oceanology, is the study of the physical and biological aspects of the ocean. It is an Earth science, which covers a wide range of topics, including ecosystem dynamics; ocean currents, waves, and geophysical fluid dynamics; plate tectonics and the geology of the sea floor; and fluxes of various chemical substances and physical properties within the ocean and across its boundaries. These diverse topics reflect multiple disciplines that oceanographers blend to further knowledge of the world ocean and understanding of processes within: astronomy, biology, chemistry, climatology, geography, geology, hydrology, meteorology and physics. Paleoceanography studies the history of the oceans in the geologic past. — Wikipedia

10 weird things you never knew about the ocean’s deepest places (Alan Jamieson, Science Alert)

Discovery

The first descent to the deepest point in the ocean in 1960 has been brought to life with an immersive 360 VR film. The voyage to full ocean depth is narrated by US Captain Don Walsh who is one of two men who retain the record to this day for the deepest ever manned submersible dive to a depth of 11km (7 miles). On 23 January 1960, the US Navy Captain, now 85, and Swiss engineer Jacques Piccard, deceased, became the first people to descend to 10,911m (35,797ft) to the bottom of the Challenger Deep aboard the Swiss-built US Navy bathyscaphe, Trieste. The Challenger Deep is the deepest known point in the Earth’s ocean and is located within the Mariana Trench in the Pacific Ocean.

    A new study finds that hypoxic dead zones occur in nutrient-laden urban streams, not just in coastal waters. The research shows that intense storm flows can erode some stream channels to become a series of pools that trap nutrient-laden runoff. The elevated nutrient levels in the water spur greater […]
