Though generally described as several separate oceans, the global, interconnected body of salt water is sometimes referred to as the World Ocean or global ocean.[15][16] The concept of a continuous body of water with relatively free interchange among its parts is of fundamental importance to oceanography.[17] We give youth access to high-level conversation and a platform to showcase their ideas and solutions that can protect our ocean. We foster the entrepreneurial spirit of our members and challenge them to design creative policy and business solutions. SOA currently supports over 160 youth-led sustainability projects around the globe. Oceana Canada, an ocean research charity, is hoping citizen scientists in Halifax armed with DNA kits will help them sniff out seafood fraud. (Elaine Thompson/Associated Press) Według hipotezy ekspandującej Ziemi powstanie oceanów było aktem jednorazowym. Zgodnie z nią rozrost skorupy powoduje powiększanie się wszystkich oceanów i całej planety, był więc taki moment, kiedy nie było na Ziemi oceanów w dzisiejszym znaczeniu. Hipoteza ta nie potrafi wytłumaczyć istnienia ofiolitów, czyli zespołów skał identycznych z powstającymi pod powierzchnią oceanów, a znajdujących się obecnie niekiedy w głębi kontynentu. The deepest point in the ocean is the Mariana Trench, located in the Pacific Ocean near the Northern Mariana Islands. Its maximum depth has been estimated to be 10,971 meters (35,994 ft) (plus or minus 11 meters; see the Mariana Trench article for discussion of the various estimates of the maximum depth.) The British naval vessel Challenger II surveyed the trench in 1951 and named the deepest part of the trench the “Challenger Deep”. In 1960, the Trieste successfully reached the bottom of the trench, manned by a crew of two men. The partnership spans fisheries, aquaculture, oil and gas, marine bio products, transportation, defence, marine renewables, and ocean technology. Companies are collaborating to define a shared innovation roadmap based on common challenges and requirements. To put into perspective just how deep the oceans go, Xkcd.com created the illustration below (click the image for a larger version). The Soft Robotic Fish, aka SoFi, is a hypnotic machine, the likes of which the sea has never seen before. In a paper published today in Science Robotics, MIT researchers detail the evolution of the world’s strangest fish, and describe how it could be a potentially powerful tool for scientists to study ocean life. Though generally described as several separate oceans, the global, interconnected body of salt water is sometimes referred to as the World Ocean or global ocean.[15][16] The concept of a continuous body of water with relatively free interchange among its parts is of fundamental importance to oceanography.[17] “We made ocean mining seem a lot more credible,” Sharp says. “We really misled a lot of people and it’s surprising that the story held together for so long.” ©2018 Ocean.io · 1A, Heienhaff · L-1736 Senningerberg · Luxembourg · hello@ocean.io One reason fish are so diverse is that 70 percent of the planet is covered in water. The animals in this group live in a variety of habitats ranging from coral reefs and kelp forests to rivers, streams, and the open ocean. Another is that fish are very old on the evolutionary scale. According to fossil records, they have been on Earth for more than 500 million years! The total number of living fish species—about 32,000— is greater than the total of all other vertebrate species (amphibians, reptiles, birds, and mammals) combined. It looks like a fish, moves like a fish, but it’s definitely a robot. It’s name is SoFi (short for soft robotic fish), and according to its creators at MIT’s computer science and AI lab CSAIL, it’s the most versatile bot of its kind. And with its built-in cameras, scientists should be able to use SoFi to get close to the ocean’s inhabitants without spooking them — hopefully giving us greater insight into the lives of under-observed sea creatures. Scientists are investigating the role microbiomes play in coral health, trying to identity those microbial traits that make coral reefs resilient as ocean temperatures rise and bleaching events accelerate.9 days ago Thank the ocean with every breath you take, says Dr Sylvia Earle The Decade will act to fill major gaps in our knowledge of the ocean and ability to sustainable manage its resources: It’s time to give our ocean our full attention. One of the authors, Prof Edward Hill from the UK National Oceanography Centre told BBC News: “The ocean is critical to our economic future. Nine billion people will be looking to the ocean for more food. Yet we know so little of what’s down there. SOA’s mission is reinforced through our national and international high school, university, and young professional chapters. Our goal is to have 200 global chapters by 2018, each focused on developing advocacy campaigns targeting local elected officials, hosting community-centered impact events, and raising awareness about the common responsibility to protect our ocean. But today, Pardo’s vision is becoming reality as the UN’s International Seabed Authority has drawn up maps dividing the ocean into blocks. Scientists designed SoFi to solve several problems that bedevil oceanic robotics. Problem one: communication. Underwater vehicles are typically tethered to a boat because radio waves don’t do well in water. What SoFi’s inventors have opted for instead is sound. Zdaniem naukowców wielkość oceanu jest zbliżona do amerykańskiego Lake Superior, czyli drugiego największego jeziora na Ziemi.  A school of 6 cod fish swimming in an ocean. Our oceans have absorbed most of the planet’s warming—over 90%—and a significant amount of our carbon pollution. Warmer oceans are driving stronger storms and bleaching coral reefs. As oceans absorb carbon dioxide, they become more acidic, threatening most shelled organisms, including small crustaceans fundamental to the marine food chain. One of the most dramatic forms of weather occurs over the oceans: tropical cyclones (also called “typhoons” and “hurricanes” depending upon where the system forms). The Antarctic Circumpolar Current encircles that continent, influencing the area’s climate and connecting currents in several oceans.

Prominent contributors include dissolved organic matter and chlorophyll.[31] Mariners and other seafarers have reported that the ocean often emits a visible glow which extends for miles at night. In 2005, scientists announced that for the first time, they had obtained photographic evidence of this glow.[32] It is most likely caused by bioluminescence.[33][34][35] GCOS Implementation Plan 2016   !NEW!

More information The first inkling that the ocean floor might hold a treasure trove of minerals came in the late 19th Century when a Royal Navy ship, HMS Challenger, was sent on a pioneering expedition. Instead of exploring the coasts of new lands, the ship was to investigate the oceans themselves. Oceans X Labs, a joint initiative of Conservation X Labs and WWF, is matching big ideas with the brightest minds in search of solutions to the global challenges of oceans conservation. Ocean’s design is influenced by its coastal setting. Blues, whites and beiges create a modern classic look, while delightful hand-crafted furniture and specially commissioned artwork emphasise the feeling of luxury. White American shutters frame stunning views over the gardens to the ocean beyond. The Foresight reports are written by experts to brief ministers on medium and long-term issues of significance. This one has been signed off by ministers from four different departments as the authors emphasise the need for a joined-up oceans policy. The federal government and private sector’s co-investment in the Ocean Supercluster positions Canada to become a global leader in the knowledge-based ocean economy. Call of the Ocean.
