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. Agitated Ocean – ciemny turkus przytłumiony błękitem, z którym odkryjesz ocean możliwości. Wyrazista barwa stworzy świetne połączenie z każdym kolorem palety i nie pozwoli Ci pozostać w cieniu. 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] 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. Protect the ocean and you protect yourself 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] Ocean resources are one of Canada’s most significant potential advantages, with the longest coastline and the fourth largest ocean territory in the world. The Ocean Supercluster will foster new partnerships with industry, post-secondary, government, and other partners, including indigenous communities, to accelerate innovation and commercialization and to drive increased sustainable economic growth from our oceans. The deep ocean houses an ecosystem that has learned to thrive without sunlight or warmth. Welcome to the abyss. Puffer fish and tropical fish spawn in lukewarm and warm oceans. The rariphotic is a sort of “missing link” between medium-light reef zones and the lightless ocean beneath, known as the aphotic zone. Endangered Waves can empower and incentivize surfers (there are 24 million worldwide) to monitor the health of their coastlines through crowdsourced data. Surfers can use this app to create crowdsourced data to identify and then reduce hazards in their local surf breaks. In the US, tourism and recreation comprise 72% of employment in the ocean economy and 31% of its gross value. Creating apps that cater to this market isn’t indulgent, it’s good business sense. Uncover the secrets of the largest animals in the ocean. ©2018 Ocean.io · 1A, Heienhaff · L-1736 Senningerberg · Luxembourg · hello@ocean.io 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 Kantor ocean to idealne miejsce dla osób, które stawiają na wygodę, bezpieczeństwo i oszczędności.

Zdaniem naukowców wielkość oceanu jest zbliżona do amerykańskiego Lake Superior, czyli drugiego największego jeziora na Ziemi.  Exploring the extreme environment of the deep sea requires special technology. Enter a research habitat based on real ocean laboratories. Climb into an actual submarine, learn how sonar works, and “fly” a remote operated vehicle (ROV) as you explore the wonders of the undersea world. 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? „Życie to podróż, to ocean” to zapis rozmowy jaką Artur Cieślar odbył z Julią Hartwig, poetką, tłumaczką, eseistką. To niezwykle miła pogawędka dwojga wyważonych, pogodzonych z losem ludzi, którzy ową harmonią, spokojem i ciepłą atmosferą czarują czytelnika od pierwszych słów. Julia Hartwig początkowo nie chciała się zgodzić na ten wywiad. Jest skromna, nie lubi zamieszania wokół siebie i nie przepada za opowiadaniem o swojej osobie. Na tę publikację namówił ją dopiero jej wieloletni przyjaciel, Jerzy Illg. Powstała w ten sposób niewielkich rozmiarów książeczka, w której pani Julia robi wszystko, byle pozostać w cieniu. Żałuję ogromnie, iż autoryzując tekst, usunęła najbardziej intymne zwierzenia i pozbawiła swoich czytelników możliwości głębszego poznania. “Najważniejsze jest to, czy mam coś do przekazania. Jeśli nie, to szkoda sobie i innym zabierać czas”, wyznaje autorka. Widocznie jej przekaz nie musi być pokaźnych rozmiarów, by robił wrażenie. Czy zatem mamy szansę natrafić w… 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. “One Ocean” takes viewers on a journey from the intense heat of the tropics to the planet’s frozen poles. Life has spread to almost every part of the ocean, but there are many different worlds within it, and each presents unique challenges. 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 Although no-one has yet started mining the ocean floor, dozens of research expeditions are under way “at an intense pace”, says Michael Lodge, from the International Seabed Authority. In addition, the Institute fosters the democratization of ocean science by offering media workshops and immersive educational experiences to the public. We actively connect artists and advocates, scientists and students, media-makers and policy-makers in an effort to engage them in collective artistic approaches that address ocean issues. Cod spawn in normal, cold, and lukewarm oceans. Ocean currents greatly affect Earth’s climate by transferring heat from the tropics to the polar regions. Transferring warm or cold air and precipitation to coastal regions, winds may carry them inland. Surface heat and freshwater fluxes create global density gradients that drive the thermohaline circulation part of large-scale ocean circulation. It plays an important role in supplying heat to the polar regions, and thus in sea ice regulation. Changes in the thermohaline circulation are thought to have significant impacts on Earth’s energy budget. In so far as the thermohaline circulation governs the rate at which deep waters reach the surface, it may also significantly influence atmospheric carbon dioxide concentrations. Call of the Ocean.
