Oceana Canada, an ocean research charity, is hoping citizen scientists in Halifax armed with DNA kits will help them sniff out seafood fraud. This acceleration of the current takes place in the direction of waves and dominant wind. Accordingly, when the sea depth increases, the rotation of the earth changes the direction of currents, in proportion with the increase of depth while friction lowers their speed. At a certain sea depth, the current changes direction and is seen inverted in the opposite direction with speed current becoming nul: known as the Ekman spiral. The influence of these currents is mainly experienced at the mixed layer of the ocean surface, often from 400 to 800 meters of maximum depth. These currents can considerably alter, change and are dependent on the various yearly seasons. If the mixed layer is less thick (10 to 20 meters), the quasi permanent current at the surface adopts an extreme oblique direction in relation to the direction of the wind, becoming virtually homogeneous, until the Thermocline.[38] Nautilus Minerals forecasts that in copper alone an emerging undersea industry in oceans around the world could be worth $30bn a year by 2030. And it claims that by mining a small area of seabed, the venture will be friendlier to the environment. It contrasts its work with mines on land where trees and topsoil are swept away across vast areas. The word « ocean » comes from the figure in classical antiquity, Oceanus (/oʊˈsiːənəs/; Greek: Ὠκεανός Ōkeanós,[13] pronounced [ɔːkeanós]), the elder of the Titans in classical Greek mythology, believed by the ancient Greeks and Romans to be the divine personification of the sea, an enormous river encircling the world. The Ocean Supercluster recognizes that ocean strengths and capabilities—largely in the Atlantic Provinces—can be leveraged to accelerate the development and benefits of ocean resources for all of Canada. “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.” Seychelles has announced two new Marine Protected Areas covering 210,000 square kilometers of biodiverse ocean waters. 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 Advocates of exploiting the ocean also point to the size of mines on land compared with those that would be operated underwater. Kennecott in Utah and Chuquicamata and Escondida in Chile involve mind-bogglingly large holes in the ground. They stretch nearly three miles across (4km) and reach more than half a mile deep (645m-1200m). 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] Thank you for considering a donation to Ocean Media Institute.

Consumer products giant P&G is tackling marine pollution by creating bottles made from beach plastic and developing new technologies to reduce waste. P&G’s Virginie Helias talks about the importance of collaboration to solve the ocean plastic crisis.27 days ago The UN Decade of Ocean Science seeks to transform and bolster the way in which the scientific community, governments, civil society, and the UN System coordinate their actions toward “conserving and sustainably using the oceans, seas and marine resources for sustainable development” – as stated in Objective 14 of the Sustainable Development Goals. Professor Richard Twitchett explains what a more acidic ocean could mean for the future of marine life. Contact us: How: Develop a mobile app that unlocks ocean data for public and/or private benefit, ideally while supporting responsible use and protection of our ocean. 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 +44 (0)20 7292 6161 Terms & Conditions Test your ocean smarts and answer five quick questions to see how deep your ocean knowledge goes. Tins of tuna state that they are “dolphin-friendly” so should products using cobalt say if the metal was mined on land or in the ocean? What would the best choice be anyway? Should the vents so special to Attenborough be spared and only nodule mining allowed? The report says much more knowledge is needed about the ocean. The authors say the world needs a Mission to “Planet Ocean” to mirror the excitement of voyaging to the moon and Mars. “It’s estimated that 95 per cent of the liveable space on our planet is in the ocean,” said Dr Carole Baldwin, curator of fishes at the Smithsonian’s National Museum of Natural History and lead author of the study. In an air-conditioned cabin in a teeming port in Papua New Guinea, Leslie Kewa reaches for a joystick that will control a machine the size of a house. Nearly half a century after the CIA men pretended to mine the ocean floor, he’s about to do it for real. Pledge to work together to solve the world’s greatest environmental problems and protect our oceans. 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. 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 A mission to map the hidden ocean floor 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.
