The total mass of the hydrosphere is about 1.4 quintillion metric tons (7018140000000000000♠1.4×1018 long tons or 7018150000000000000♠1.5×1018 short tons), which is about 0.023% of Earth’s total mass. Less than 3% is freshwater; the rest is saltwater, almost all of which is in the ocean. The area of the World Ocean is about 361.9 million square kilometers (139.7 million square miles),[9] which covers about 70.9% of Earth’s surface, and its volume is approximately 1.335 billion cubic kilometers (320.3 million cubic miles).[9] This can be thought of as a cube of water with an edge length of 1,101 kilometers (684 mi). Its average depth is about 3,688 meters (12,100 ft),[9] and its maximum depth is 10,994 meters (6.831 mi) at the Mariana Trench.[29] Nearly half of the world’s marine waters are over 3,000 meters (9,800 ft) deep.[16] The vast expanses of deep ocean (anything below 200 meters or 660 feet) cover about 66% of Earth’s surface.[30] This does not include seas not connected to the World Ocean, such as the Caspian Sea. ocean late 13c., from O.Fr. occean (12c.), from L. oceanus, from Gk. okeanos, the great river or sea surrounding the disk of the Earth (as opposed to the Mediterranean), of unknown origin. Personified as Oceanus, son of Uranus and Gaia and husband of Tethys. In early times, when the only known land masses were Eurasia and Africa, the ocean was an endless river that flowed around them. Until c.1650, commonly ocean sea, translating L. mare oceanum. Application to individual bodies of water began 14c.; there are usually reckoned to be five of them, but this is arbitrary; also occasionally applied …to smaller subdivisions, e.g. German Ocean “North Sea.” 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 goal of the Big Ocean Button Challenge is to advance development of and investment in ocean data products and services. Many sectors can benefit from solutions for organizing and standardizing ocean data. Some applications that are in need of ocean services include: As scientists from around the world gathered in San Diego this week at the Sixth International Marine Debris Conference, much of the discussion has been about plastic pollution of the ocean. In particular, synthetic microfibers that clothing sheds in washing machines passing through wastewater treatment plants and into the sea. 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] By 2050 there will be more plastic than fish in our oceans. To reverse this trend, we need to take action! Take the pledge and commit to reducing your usage of plastics.

The gas giants, Jupiter and Saturn, are thought to lack surfaces and instead have a stratum of liquid hydrogen, however their planetary geology is not well understood. The possibility of the ice giants Uranus and Neptune having hot, highly compressed, supercritical water under their thick atmospheres has been hypothesised. Although their composition is still not fully understood, a 2006 study by Wiktorowicz and Ingersall ruled out the possibility of such a water “ocean” existing on Neptune,[60] though some studies have suggested that exotic oceans of liquid diamond are possible.[61] If a zone undergoes dramatic changes in temperature with depth, it contains a thermocline. The tropical thermocline is typically deeper than the thermocline at higher latitudes. Polar waters, which receive relatively little solar energy, are not stratified by temperature and generally lack a thermocline because surface water at polar latitudes are nearly as cold as water at greater depths. Below the thermocline, water is very cold, ranging from −1 °C to 3 °C. Because this deep and cold layer contains the bulk of ocean water, the average temperature of the world ocean is 3.9 °C.[citation needed] If a zone undergoes dramatic changes in salinity with depth, it contains a halocline. If a zone undergoes a strong, vertical chemistry gradient with depth, it contains a chemocline. A team at Massachusetts Institute of Technology has unveiled their own solution—an ultrasound-controlled, soft robotic fish. It’s not the only fish robot out there, but it could be the first that can swim in three dimensions, untethered, in the open ocean. Such a robot has the potential to transform the way biologists study the ocean. In-depth coverage of ocean health. Learn more about us. 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. 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! Obszar szelfu i stoku kontynentalnego są zbudowane ze skorupy kontynentalnej i przez geologów zaliczane do kontynentów. Obszary basenów oceanicznych, rowów oceanicznych i grzbietów śródoceanicznych mają skorupę typu oceanicznego i tworzą właściwy wszechocean. Formą pośrednią są tzw. mikrokontynenty – obszary położone na dnie oceanu, całkowicie lub prawie całkowicie przykryte wodą, a zbudowane ze skorupy kontynentalnej lub mieszanej. Scientists have attributed an algal bloom that killed off $800 million worth of salmon in Chile to rising ocean temperatures, and they say other aquaculture operations around the world are at risk.about 1 month ago When you purchase the 4Ocean Signature Blue and Limited Edition Coral Reef Bracelets, we will remove two pounds of trash from the ocean and coastlines and also help to restore and regrow coral reefs through our partnership with the Coral Restoration Foundation*. These bracelets represent your support. 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. extension ciglia 3d prodotti deseo erfahrungen mann ejercicios para aumentar los gluteos de forma natural agrandar el pené ejercicios masa muscular o definicion come si allunga il pene pastilla de ereccion aumentare muscoli fibre rosse esercizi penetranza como agrandar los labios con botella droge spieren dieet peñiscola plaza suites todo incluido oferta como aumentar gluteos y piernas en 2 semanas calorie piselli verdi cotti comment prendre du poids quand on est trop mince como alargar el miembro masculino ricostruzione unghie piedi cartina hoe spiermassa opbouwen agrandir son zizi naturellement vitaminas para alargar el pene vad är erektil dysfunktion proteinas para aumentar musculos gain de masse rapide come far allungare il pisello integratori massa muscolare pro e contro gel pene arandas menu frankfort ky order online ejercicios para aumentar gluteos rapido erektionsprobleme junge männer ursachen modificare grandezza icone desktop windows 10
