World Oceans Day is June 8: 82 Facts About Our Oceans

World Oceans Day was established in 2002 by the United Nations to protect and celebrate Oceans. We pulled together some oceans facts that demonstrate why saving our oceans is crucial to not only personal and fiscal health but the health of the planet.

70% of the world is covered by Oceans.
Historically, there are four named oceans: the Atlantic, Pacific, Indian, and Arctic. However, most countries – including the United States – now recognize the Southern (Antarctic) as the fifth ocean. The Pacific, Atlantic, and Indian are known as the three major oceans. (NOAA)
The Southern Ocean is the ‘newest’ named ocean. It is recognized by the U.S. Board on Geographic Names as the body of water extending from the coast of Antarctica to the line of latitude at 60 degrees South. The boundaries of this ocean were proposed to the International Hydrographic Organization in 2000. However, not all countries agree on the proposed boundaries, so this has yet to be ratified by members of the IHO. The U.S. is a member of the IHO, represented by the NOS Office of Coast Survey.
The Arctic Ocean is almost completely covered in sea ice during the winter.
Only 5% of the world’s Oceans have been explored.
Deep Sea refers to the part of the ocean where light does not penetrate. This is about 300 feet under the surface.
The surface of the ocean absorbs over half the heat reaching the Earth from the sun. By distributing this heat around the world, ocean currents – which flow for thousands of kilometres, both at the surface and far below – are extremely important in determining the climate of the world’s continents.

The deepest dive by a human submersible vehicle was done in the Mariana Trench in 1960 by Jacques Piccard and Don Walsh.
Oceans have an average depth of two and a half miles (13200 ft)
Rivers and Lakes are also in the ocean. This occurs when salty water and hydrogen sulfide mix to form a dense brine that is heavier than regular seawater.
There are also underwater hot springs, chimneys that spew sulfuric acid in the oceans.
Kelp Forests can go from the ocean bottom to the surface. Kelp can grow up to 2 feet per day.
The exact number of marine wildlife is not known. There are estimates the numbers could be in the millions.
94% of all life forms on Earth are aquatic.
Ocean Tides are caused by the Moon and the Sun’s gravity pulls on the ocean water when the Earth Rotates caused by the Earth rotating while the Moon and Sun’s gravitational pull acts on ocean water.
20 Million Tons of gold is estimated that the world’s oceans and seas contain.
The ocean is also mined for minerals (salt, sand, gravel, and some manganese, copper, nickel, iron, and cobalt can be found in the deep sea) and drilled for crude oil.
Oceans are the worlds largest museums. relics, artifacts, ruins, and shipwrecks exist and lost cities exist under the ocean.
The lost city of Thonis/Heracleion off the coast of Egypt was discovered in 2000.
Lion City was named due to Five Lion Mountain loomed large behind it. The city, also known as Shi Cheng, has been buried beneath the water for 53 years in China
50%of United States’ legal jurisdiction territory are under the ocean.
Sound travels fastest and further in the ocean at an underwater speed of 1435m per second. That is almost 5x faster than in air.
Many ocean animals communicate, navigate and forage food by sound. human-generated ocean noise pollution is altering the underwater acoustic landscape, harming—and even killing—marine species worldwide.
Negative responses to anthropogenic noise have been demonstrated in at least 27 species of marine mammals in scientific studies (Source)
Oceans are worth at least $24 trillion, according to a new WWF report Reviving the Ocean Economy
90% of trade between countries is carried by ships.
10,000 Shipping Containers Lost At Sea Each Year. (one report) another states 1390 shipping containers are lost at sea every year. (2017)
50% (about) of the world’s lives in a coastal zone
The ocean is #1 source of protein for more than a billion people.
140 million jobs are provided by the ocean.
Ocean-based businesses, from fishing to medical to tourism contribute more than $500 billion to the world’s economy.
Overfishing is one of the biggest threats to the health of seas.

If all the glaciers, icebergs, and ices sheets meltes in an instant, sea levels would rise 262 feet. This would fully submerge most coastal cities in the world.
20-25% of dredging waste ends in oceans. This includes toxic chemicals which are a death sentence for ocean life and humans.
It is estimated that air pollution is responsible for at least one-third of toxic contaminants that are dumped on a yearly basis onto oceans and other bodies of water.

75% of the world’s coral reefs are at risk from local and global stresses. About a quarter of them have already been damaged beyond repair.
90% of coral reefs will be in danger by 2030, and nearly all of them by 2050 if human continue doing what we do now. (State of the Planet)
Coral Reef Locations
A study of 159 reefs in the Pacific found that plastic pollution is killing coral. When coral reefs come into contact with plastic waste, the incidence of disease rises 20x.
The Great Pacific Garbage patch, a floating plastic garbage island was discovered in 1997 by sailing Captain Charles Moore by accident.
The North Pacific Garbage Patch is located about 1,000 miles northeast of Hawaii and about 1,000 miles off the coast of California.

6x as much plastic as plankton are in the ocean garbage patches. Marine animals eat plankton and humans eat marine animals.
2011: Scientists from UC San Diego found plastic in 9.2% of the fish they studied in over 1700 miles of the Pacific Garbage Patch. Based on this 2011 study, researchers estimate that the fish in the North Pacific Ocean consume plastic at a rate of roughly 12,000 to 24,000 tons per year.
The Oceans absorb as much as a quarter of all man-made carbon emissions, which changes the pH of surface waters and leads to acidification.. leading to climate change.

405+ dead zones are identified in the world. That is up from 49 in the 1960.Fertilizer runoff and fossil-fuel use lead to massive areas in the ocean with scant or no oxygen, killing large swaths of sea life and causing hundreds of millions of dollars in damage
Image: Wikipedia Dead Zone Ecology. Dead zones are often caused by the decay of algae during algal blooms, like this one off the coast of La Jolla, San Diego, California.
The worlds largest dead zone is in the Baltic Sea, whose bottom waters now lack oxygen year-round.
The five biggest threats to the ocean: Overfishing, illegal fishing, Coastal pollution, Habitat destruction, Warming, Acidification, Mining.

In conclusion, as human continue to destroy the oceans… nobody wins.
