Uncover the secrets of the largest animals in the ocean. 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] Just how deep does the ocean go? Way further than you think. This animation puts the actual distance into perspective, showing a vast distance between the waves we see and the mysterious point we call Challenger Deep.

The possibility continues to be studied along with reasons for their apparent disappearance. Astronomers think that Venus had liquid water and perhaps oceans in its very early history.[citation needed] If they existed, all later vanished via resurfacing. But there’s no other option. The machine will soon be deployed not in the huge pits of an opencast mine on land but in the sunless depths a mile underwater on the ocean floor. Beaked whales can dive 2,000 metres below the ocean’s surface. Why and how do they do it? We’ve drilled the ocean floor for oil and gas, scarred it with trenches for communications cables, poisoned it with old radioactive waste and chemical weapons, and polluted its remotest corners with a blizzard of discarded plastic. So, is mining a step too far? Plastic is everywhere – even the deepest parts of the ocean are now awash with it. Ta rozmowa jest jak życie, raz płynie jak wartka rzeka, innym razem powolutku – delikatnie zaczepiając o problematyczne skałki a czasem zupełnie jak wzburzony ocean. Jestem naprawdę zauroczona osobowością, pozytywnym nastawieniem i otwartością Pani Julii 🙂 Fantastyczna książka. Gorąco polecam! SeaSee App shows us what the world would look like if the oceans were drained of water, using bathymetric (seafloor depth) data to generate 3D views. This app allows you to explore the ocean floor, from shipwrecks to marine habitats. Na niektórych ciałach położonych poza klasycznie definiowaną ekosferą mogą istnieć podpowierzchniowe zbiorniki ciekłej wody. Niektóre z nich tworzą płynną warstwę wody otaczającą cały glob, pokrytą skorupą lodową o wielokilometrowej grubości. Taki podpowierzchniowy ocean posiadają niektóre księżyce planet, w szczególności Europa, a także prawdopodobnie Ganimedes i Kallisto, dwa inne galileuszowe księżyce Jowisza oraz Tytan i Enceladus, krążące wokół Saturna[6]. Ocean na Europie przypuszczalnie ma kontakt ze skalistym wnętrzem księżyca i na jego dnie może mieć miejsce aktywność wulkaniczna lub hydrotermalna; także ocean na Enceladusie rozciąga się między lodową skorupą a skałami[7]. Prawdopodobne oceany na trzech największych księżycach lodowych są uwięzione pomiędzy dwiema warstwami lodu o różnej strukturze krystalicznej i gęstości[8]. Modele ewolucji termicznej wskazują także na możliwość powstania takich zbiorników na niektórych większych obiektach transneptunowych[9] (plutoidach). I knew we were going towards the ocean; and my great cause of apprehension was the bar. Lanternfish are one of many animals that light up the ocean with their glowing bodies. “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. SOpHIE was designed to serve those working in aquaculture, fisheries, and coastal monitoring, by delivering daily metrics of ocean acidification.This app lets users know if a site that matters to them is at risk from ocean acidification. 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) 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. “Where we’ll be operating, it’s cold and dark,” says one senior Nautilus executive. “There are no tuna there, they need entirely different conditions near the surface of the ocean.” Earth may be the blue planet, but beneath the ocean waves lies a vast forest of green.  As the world ocean is the principal component of Earth’s hydrosphere, it is integral to 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 in the ocean is much larger, possibly over two million.[10] The origin of Earth’s oceans is unknown; oceans are thought to have formed in the Hadean eon and may have been the impetus for the emergence of life. 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] The benthic zones are aphotic and correspond to the three deepest zones of the deep-sea. The bathyal zone covers the continental slope down to about 4,000 meters (13,000 ft). The abyssal zone covers the abyssal plains between 4,000 and 6,000 m. Lastly, the hadal zone corresponds to the hadalpelagic zone, which is found in oceanic trenches. Early ancestors of the ocean’s biggest animals once walked on land. Follow their extraordinary journey from shore to sea.  The amount of noise in the ocean has doubled each decade since the 1950s. 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] Early ancestors of the ocean’s biggest animals once walked on land.
