Do głównych form ukształtowania dna oceanicznego zalicza się: A global layer of liquid water thick enough to decouple the crust from the mantle is thought to be present on the natural satellites Titan, Europa, Enceladus and, with less certainty, Callisto, Ganymede[62][63] and Triton.[64][65] A magma ocean is thought to be present on Io. Geysers have been found on Saturn’s moon Enceladus, possibly originating from about 10 kilometers (6.2 mi) deep ocean beneath an ice shell.[57] Other icy moons may also have internal oceans, or may once have had internal oceans that have now frozen.[66] Cameron visited the Mariana Trench, the deepest place on Earth at 7 miles (11 km) below the surface of the Pacific Ocean, in a minisubmarine in 2012. He was only the second person to visit that area of the ocean. 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’s always been there, but a layer of the ocean is so distinct from the waters above and below it that it needed its own category. Why: Bring app developers to the trove of available ocean data in order to catalyze the growth of a potentially multi-billion-dollar industry in ocean data products. “It’s estimated that 95 percent of the livable space on our planet is in the ocean, yet only a fraction of that space has been explored,” said study lead author Carole Baldwin of the NMNH. Scientists testing North Atlantic mesopelagic fish eaten by the ocean’s top predators found that nearly 75 percent were contaminated with microplastic fibers. Researchers have also discovered microplastics in the scat of gray seals and in the Atlantic mackerel they eat.23 days ago To put into perspective just how deep the oceans go, Xkcd.com created the illustration below (click the image for a larger version). Thank the ocean with every breath you take, says Dr Sylvia Earle Zdaniem naukowców wielkość oceanu jest zbliżona do amerykańskiego Lake Superior, czyli drugiego największego jeziora na Ziemi.  Test your ocean smarts and answer five quick questions to see how deep your ocean knowledge goes. In the broad pathways of the ocean such a chance is doubtful. Według tektoniki płyt skorupa ziemska powstaje w przybliżeniu w takim samym tempie, w jakim jest niszczona w strefach subdukcji, a łączna objętość oceanów nie ulega zmianie (nie licząc rozrostu i topnienia lodowców). Jedne oceany mogą powiększać się tylko kosztem innych; w historii Ziemi istniały zbiorniki oceaniczne, które zamknęły się na skutek ruchu kontynentów (paleooceany), a ich osady wypiętrzyły się tworząc łańcuchy górskie (m.in. Himalaje). Dzisiejsze oceany Atlantycki, Arktyczny i Indyjski są geologicznie młodymi oceanami, które powstały w erze mezozoicznej i rozrastają się obecnie kosztem Pacyfiku. Earth may be the blue planet, but beneath the ocean waves lies a vast forest of green.  The Proclamation of the Decade of Ocean Science for Sustainable Development by the UN General Assembly marks the beginning of a process of consultations with all ocean stakeholders, coordinated by UNESCO’s IOC, to prepare a concerted Decade Implementation Plan. 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 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. The Nintendo controller speaks to the fish by sending vibrations through the ocean at frequencies higher than humans can hear. These pulses are essentially commands translated into binary code (or perhaps Morse code), which the robo-fish can read despite the background vibrations of the ocean. The researchers tested their creation out in the Pacific Ocean, at depths from zero to 18 meters (59 feet), according to the study published today in Science Robotics. There, we might find something to eat; of which there was little hope, out on the ocean. There’s a lot we don’t know about the ocean, simply because it’s so difficult for us to access. It was only thanks to advances in submersible technology that marine scientists have been able to explore down below the reef off the coast of Curaçao. He told BBC News: “There’s a continuous process of exploring for new things to exploit in the oceans, and that’s happening faster than we scientists can keep up with. My suspicion is legislation is also struggling to keep up – and obviously there are risks in that.” As mandated by the UN General Assembly, the Intergovernmental Oceanographic Commission (IOC) of UNESCO will coordinate the Decade’s preparatory process, inviting the global ocean community to plan for the next ten years in ocean science and technology to deliver, together, the ocean we need for the future we want! To keep oceans healthy, we must fully understand the science of diverse fisheries and build management systems to control when, where, how, and how much people fish.  The Sustainable Ocean Alliance (SOA) is a global organization that advances the impact of start-ups, social enterprises and youth-centered initiatives that are developing solutions to protect and sustain our ocean. SOA’s pipeline of ocean leaders, ages 16-35, is cultivated through a chapter-based model, led by students at the high school and college levels, as well as by young professionals. But even more alarming was the suspicion of the Russians. To convince them that Howard Hughes was genuinely interested in nodules, executives were despatched to conferences on ocean mining where they described in detail their plans to harvest the rocks. “That’s understandable for areas that are thousands of miles offshore and miles deep. But tropical deep reefs are just below popular, highly studied shallow reefs – essentially our own backyards. And tropical deep reefs are not barren landscapes on the deep ocean floor: they are highly diverse ecosystems that warrant further study. We hope that by naming the deep-reef rariphotic zone, we’ll draw attention to the need to continue to explore deep reefs.” But his instrument was never used on the ocean lines, and, indeed, it was not adapted for them.
