Oceans, seas, lakes and other bodies of liquids can be composed of liquids other than water, for example the hydrocarbon lakes on Titan. The possibility of seas of nitrogen on Triton was also considered but ruled out.[74] There is evidence that the icy surfaces of the moons Ganymede, Callisto, Europa, Titan and Enceladus are shells floating on oceans of very dense liquid water or water–ammonia.[75][76][77][78][79] Earth is often called the ocean planet because it is 70% covered in water.[80][81] Extrasolar terrestrial planets that are extremely close to their parent star will be tidally locked and so one half of the planet will be a magma ocean.[82] It is also possible that terrestrial planets had magma oceans at some point during their formation as a result of giant impacts.[83] Hot Neptunes close to their star could lose their atmospheres via hydrodynamic escape, leaving behind their cores with various liquids on the surface.[84] Where there are suitable temperatures and pressures, volatile chemicals that might exist as liquids in abundant quantities on planets include ammonia, argon, carbon disulfide, ethane, hydrazine, hydrogen, hydrogen cyanide, hydrogen sulfide, methane, neon, nitrogen, nitric oxide, phosphine, silane, sulfuric acid, and water.[85] OMI serves to enrich and expand the public’s understanding of ocean science and conservation through the collaborative creation, exhibition, and open-distribution of innovative visual media as well as artistic approaches to ocean education. 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 The ocean has a significant effect on the biosphere. Oceanic evaporation, as a phase of the water cycle, is the source of most rainfall, and ocean temperatures determine climate and wind patterns that affect life on land. Life within the ocean evolved 3 billion years prior to life on land. Both the depth and the distance from shore strongly influence the biodiversity of the plants and animals present in each region.[41] Urge NOAA to strengthen its plan to reduce industrial ocean noise. Jim Mosher of Clearwater Seafood discusses how GIS will be critical to maintaining sustainable ocean ecosystems Istnienie oceanu na księżycu Saturna zwiększa szanse na znalezienie życia pozaziemskiego w naszym Układzie Słonecznym. Early ancestors of the ocean’s biggest animals once walked on land. Follow their extraordinary journey from shore to sea.  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. Did you know that coral reefs support more species than any other marine environment and rival rainforests in their biodiversity? 2018 is the third International Year of the Reef—a platform to highlight the importance of coral reefs. Covering less than one percent of the planet, reefs are the home to 25 percent of marine species and supply food to millions of people. They are also vital to our ocean economy, providing billions of dollars in services, such coastal protection, jobs, tourism and more. The word « ocean » comes from the figure in classical antiquity, Oceanus (/oʊˈsiːənəs/; Greek: Ὠκεανός Ōkeanós,[13] pronounced [ɔːkeanós]), the elder of the Titans in classical Greek mythology, believed by the ancient Greeks and Romans to be the divine personification of the sea, an enormous river encircling the world. Other possible candidates are merely speculated based on their mass and position in the habitable zone include planet though little is actually known of their composition. Some scientists speculate Kepler-22b may be an “ocean-like” planet.[71] Models have been proposed for Gliese 581 d that could include surface oceans. Gliese 436 b is speculated to have an ocean of “hot ice”.[72] Exomoons orbiting planets, particularly gas giants within their parent star’s habitable zone may theoretically have surface oceans. Terrestrial planets will acquire water during their accretion, some of which will be buried in the magma ocean but most of it will go into a steam atmosphere, and when the atmosphere cools it will collapse on to the surface forming an ocean. There will also be outgassing of water from the mantle as the magma solidifies—this will happen even for planets with a low percentage of their mass composed of water, so “super-Earth exoplanets may be expected to commonly produce water oceans within tens to hundreds of millions of years of their last major accretionary impact.”[73] Lifeforms native to the ocean include: We are a nonprofit systems change incubator. We work with industry players, technologists, and NGOs to create business solutions to ocean challenges. Plastic is everywhere – even the deepest parts of the ocean are now awash with it.

Many studies have shown that larvae of various fish species can be negatively affected by ocean acidification. Acidification is caused by large amounts of carbon dioxide (CO2) entering the seawater from the atmosphere. But CO2 can also influence the food supply for the fish … more Salmon spawn in cold and frozen oceans, and unlike the other 3 variants, can also spawn in rivers. The UN Decade of Ocean Science seeks to transform and bolster the way in which the scientific community, governments, civil society, and the UN System coordinate their actions toward “conserving and sustainably using the oceans, seas and marine resources for sustainable development” – as stated in Objective 14 of the Sustainable Development Goals. The Ocean Supercluster recognizes that ocean strengths and capabilities—largely in the Atlantic Provinces—can be leveraged to accelerate the development and benefits of ocean resources for all of Canada. People sometimes forget that oceans contain a lot more than the water you see just beneath the surface. Thank you for considering a donation to Ocean Media Institute. As a creative media hub, OMI fosters the democratization of ocean science by working collaboratively with organizations, academic institutions, aquaria, and museums across the globe to produce and openly distribute innovative visual stories to address ocean issues. You can be assured that any financial contribution you make will go directly to expanding our shared vision for ocean conservation. A global collective bringing the ocean and its importance to the most connected generation in history. Supported by UNOPS. But today, Pardo’s vision is becoming reality as the UN’s International Seabed Authority has drawn up maps dividing the ocean into blocks. We very much want you on board this wave, with upswells worldwide of people who will inherit the oceans.   Innovation and technology are essential components in our effort to restore the health of the ocean. SOA’s Ocean Solutions Accelerator encourages entrepreneurship and advances the initiatives of ocean-focused startups with revenue-generating technology solutions. Oceanographers divide the ocean into different vertical zones defined by physical and biological conditions. The pelagic zone includes all open ocean regions, and can be divided into further regions categorized by depth and light abundance. The photic zone includes the oceans from the surface to a depth of 200 m; it is the region where photosynthesis can occur and is, therefore, the most biodiverse. Because plants require photosynthesis, life found deeper than the photic zone must either rely on material sinking from above (see marine snow) or find another energy source. Hydrothermal vents are the primary source of energy in what is known as the aphotic zone (depths exceeding 200 m). The pelagic part of the photic zone is known as the epipelagic. SOA has the largest ocean youth network in the world, with members in 50 countries.
