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. The motions of the ocean surface, known as undulations or waves, are the partial and alternate rising and falling of the ocean surface. The series of mechanical waves that propagate along the interface between water and air is called swell.[citation needed] The depths below the ocean’s surface comprise a staggering 95 percent of the Earth’s living space, and much of it is unexplored by humans.  Ceres appears to be differentiated into a rocky core and icy mantle and may harbour a liquid-water ocean under its surface.[67][68] Researchers have found seven new animal species living along the Southwest Indian Ridge, 3,000 metres beneath the surface of the ocean, in an area targeted for deep-sea mining. Navisea is designed for planning and tracking ocean voyages, and includes data on traffic, ports, docks, navigation, and weather. This app can make navigation tools accessible to smaller vessels and marry data from the economic-focused shipping industry with the environmental-focused government and NGO datasets. While changing ocean and sea ice conditions are hurting some of Antarctica’s Adelie penguins, a newly discovered “supercolony” of 1.5 million offers new information to guide marine conservation.17 days ago But today the ocean’s reserves are overdrawn, threatening countless communities around the world with climate, economic, and food insecurities. Unsustainable development, fueled by human population growth, has weakened ocean ecosystems. Modern technology is accelerating the rate of change. Od czasu odkrycia w latach 50. XX w. zjawiska ekspansji dna oceanicznego, czyli powstawania zupełnie nowej skorupy ziemskiej w strefach grzbietów śródoceanicznych, oraz w wyniku badań wieku osadów oceanicznych i samej skorupy, rozwinęło się kilka teorii geotektonicznych, spośród których powszechnie dziś akceptowana jest teoria tektoniki płyt. Covering 72 percent of the Earth and supplying half its oxygen, the ocean is our planet’s life support system—and it’s in danger. Watch this video… more Extraterrestrial oceans may be composed of water or other elements and compounds. The only confirmed large stable bodies of extraterrestrial surface liquids are the lakes of Titan, although there is evidence for the existence of oceans elsewhere in the Solar System. Early in their geologic histories, Mars and Venus are theorized to have had large water oceans. The Mars ocean hypothesis suggests that nearly a third of the surface of Mars was once covered by water, and a runaway greenhouse effect may have boiled away the global ocean of Venus. Compounds such as salts and ammonia dissolved in water lower its freezing point so that water might exist in large quantities in extraterrestrial environments as brine or convecting ice. Unconfirmed oceans are speculated beneath the surface of many dwarf planets and natural satellites; notably, the ocean of Europa is estimated to have over twice the water volume of Earth. The Solar System’s giant planets are also thought to have liquid atmospheric layers of yet to be confirmed compositions. Oceans may also exist on exoplanets and exomoons, including surface oceans of liquid water within a circumstellar habitable zone. Ocean planets are a hypothetical type of planet with a surface completely covered with liquid.[11][12] Dolphin Days is a festive celebration of our natural world starring the ocean’s most playful ambassador, the Atlantic Bottlenose Dolphin. The value of the world’s oceans is set to double by 2030 but we know less about the bottom of the sea than we do about Mars. Supercritical fluids, although not liquids, do share various properties with liquids. Underneath the thick atmospheres of the planets Uranus and Neptune, it is expected that these planets are composed of oceans of hot high-density fluid mixtures of water, ammonia and other volatiles.[86] The gaseous outer layers of Jupiter and Saturn transition smoothly into oceans of supercritical hydrogen.[87][88] The atmosphere of Venus is 96.5% carbon dioxide, which is a supercritical fluid at its surface. While changing ocean and sea ice conditions are hurting some of Antarctica’s Adelie penguins, a newly discovered “supercolony” of 1.5 million offers new information to guide marine conservation.17 days ago This scientific research informs debates on issues including climate change, ocean acidification and plastics in the sea. WWF is working collaboratively on the brightest conservation ideas that focus on building a more resilient ocean through sustainable fishing practices and protecting important regions, like the Arctic and threatened mangrove forests. 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.

Reef ecosystems just below the mesophotic zone – the maximum depth at which tropical reef-building corals can survive – have been largely ignored by ocean explorers. An ocean (from Ancient Greek Ὠκεανός, transc. Okeanós, the sea of classical antiquity[1]) is a body of saline water that composes much of a planet’s hydrosphere.[2] On Earth, an ocean is one of the major conventional divisions of the World Ocean. These are, in descending order by area, the Pacific, Atlantic, Indian, Southern (Antarctic), and Arctic Oceans.[3][4] The word sea is often used interchangeably with “ocean” in American English but, strictly speaking, a sea is a body of saline water (generally a division of the world ocean) partly or fully enclosed by land.[5] See award-winning shots capturing life in the ocean. Professor Richard Twitchett explains what a more acidic ocean could mean for the future of marine life. The deep ocean houses an ecosystem that has learned to thrive without sunlight or warmth. Welcome to the abyss. First, there were the fish. Then (about 400 million years later) there was a lot of fishing. That’s when we came along. An eclectic bunch of design thinkers, business consultants, journalists, and scientists, we believe in the power of entrepreneurship and collaboration as potent forces for positive change in the world—including in the oceans. 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.  @oceanprime_cmr Most studies looking at how corals will respond to future increases in ocean acidity are based on laboratory studies. This week in the journal Nature, researchers reported on a large-scale experiment to simulate these conditions in a natural coral ecosystem. Uncover the secrets of the largest animals in the ocean. A new ocean cleanup prototype is being deployed on the North Sea today. It is one of the last steps as we prepare to launch the first cleanup system in the Great Pacific Garbage Patch this summer. To understand how we arrived at this point, here is a brief history of the North Sea prototypes, and the reasons why we’re deploying another… The mesopelagic area of the ocean plays a crucial role in marine ecosystems, but it has remained largely untouched and unexplored But now some nations are eyeing the deep sea as potentially rich new fishing grounds.24 days ago For adding additional datasets you want listed email or leave a comment in the Comments Thread.  The Organisation for Economic Co-operation and Development (OECD) projects that the ocean economy will more than double in size by 2030. The impact of this growth will be profound around the world and give Canada the opportunity to spur the development and adoption of technologies that will support both higher value output from ocean resources and greater sustainability in established and emerging ocean sectors.
