Under a mandate from the UN General Assembly, the Intergovernmental Oceanographic Commission of UNESCO is now working to bring together all ocean stakeholders to develop a common Implementation Plan for the UN Decade of Ocean Science. The first inkling that the ocean floor might hold a treasure trove of minerals came in the late 19th Century when a Royal Navy ship, HMS Challenger, was sent on a pioneering expedition. Instead of exploring the coasts of new lands, the ship was to investigate the oceans themselves. “We made ocean mining seem a lot more credible,” Sharp says. “We really misled a lot of people and it’s surprising that the story held together for so long.” 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… Pledge to work together to solve the world’s greatest environmental problems and protect our oceans. Test your ocean smarts and answer five quick questions to see how deep your ocean knowledge goes. Vast and wondrous, our ocean covers more than 70% of our planet. It controls the weather and climate. It provides life, food and medicine. It is key to a thriving global economy and has inspired art, poetry and tales of adventures for centuries. Yet through neglect and a startling lack of access it has lingered as an afterthought in our conservation and exploration efforts. As the world’s population grows, so does the need for food, new energy resources, new blue technologies & jobs while keeping our oceans clean. How can Blue Technology contribute? What is Norway’s role as a Sea Nation? What are the latest advances in: Aquaculture; Deep Sea Mining; Surveillance of Oceans; Autonomous Ships…?  Join us in May, LET’S TALK! A zone of rapid salinity increase with depth is called a halocline. The temperature of maximum density of seawater decreases as its salt content increases. Freezing temperature of water decreases with salinity, and boiling temperature of water increases with salinity. Typical seawater freezes at around −1.9 °C at atmospheric pressure. If precipitation exceeds evaporation, as is the case in polar and temperate regions, salinity will be lower. If evaporation exceeds precipitation, as is the case in tropical regions, salinity will be higher. Thus, oceanic waters in polar regions have lower salinity content than oceanic waters in temperate and tropical regions.[55] 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. The most important legacies of the UN Decade of Ocean Science will be a new generation of ocean scientists and technicians, with the establishment of new research networks, and a new generation of enhanced observational systems, facilities and infrastructure that will help countries achieve the 2030 Agenda for Sustainable Development. The Decade will also raise unprecedented levels of interest and participation from youth, the general public, and decision-makers around the globe. 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. See award-winning shots capturing life in the ocean. Scientists estimate more than 2 million species live in ocean waters and nine out of 10 haven’t been fully identified. The Marine Living Planet Index recorded a 36% overall decline in the abundance of marine life between 1970 and 2012. Unsustainable fishing is the primary direct threat to marine population, followed by habitat changes, which can also include a loss of food sources. 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). 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 first inkling that the ocean floor might hold a treasure trove of minerals came in the late 19th Century when a Royal Navy ship, HMS Challenger, was sent on a pioneering expedition. Instead of exploring the coasts of new lands, the ship was to investigate the oceans themselves. Zdaniem naukowców wielkość oceanu jest zbliżona do amerykańskiego Lake Superior, czyli drugiego największego jeziora na Ziemi.  4Ocean is a global movement actively removing trash from the ocean and coastlines while inspiring individuals to work together for cleaner oceans, one pound at a time. The challenges we face in managing our oceans effectively also present opportunities for innovation, collaboration, and actions. Our oceans are held in public trust, and we must act together to secure the future of our oceans and health and wealth of our nation. Together we’re building an online community for people to share ideas, collaborate, and invent technology that could help keep our oceans healthy. “We have largely thought of fish as very alien and very simple, so we didn’t really care how we killed them,” Braithwaite says. “If we look at trawl netting, that’s a pretty gruesome way for fish to die: the barometric trauma of getting ripped from the ocean into open air, and then slowly suffocating. Can we do that more humanely? Yes. Should we? Probably, yes. We’re mostly not doing it at the moment because it’s more expensive to kill fish humanely, especially in the wild.” Together we’re building an online community for people to share ideas, collaborate, and invent technology that could help keep our oceans healthy. OMI serves to enrich and expand the public’s understanding of ocean science and conservation through the collaborative creation, exhibition, and open-distribution of innovative visual media as well as artistic approaches to ocean education. “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. Early ancestors of the ocean’s biggest animals once walked on land. Follow their extraordinary journey from shore to sea.  The pelagic zone can be further subdivided into two subregions: the neritic zone and the oceanic zone. The neritic zone encompasses the water mass directly above the continental shelves whereas the oceanic zone includes all the completely open water. Graduates obtain advanced  general technical knowledge and skills necessary for creative use in the design, construction, repair and operation of ships, ocean engineering objects and systems present in the maritime sector. Graduate is prepared to execute designing and construction works in the area of ​​Ocean Engineering; conducting scientific researches in the area of ​​Ocean Engineering; production management, operation and  repairs of ships and ocean engineering objects and teamwork in an international environment. A graduate is also prepared to work in factories of widely recognized shipbuilding sector; designing and engineering offices of shipbuilding and maritime branch; R & D centres of shipbuilding and maritime economy; enterprise advisory and consulting services in the area of ​​Ocean Engineering; shipbuilding classification institutions; Maritime Administration and the international institutions of the naval sector. Graduates should have instilled habits of lifelong learning and professional development and be prepared to take up research challenges and to study the third degree. comment prendre du poid au jambe spieren kweken voeding come si allunga il pesto como hago para agrandar unos zapatos de gamuza kiihottua tipos de alargadores electricos esercizi per aumentare il busto erektionsstörungen was tun als mann impotencia 2 stravaganzza bander dure naturel esercizi per aumentare la massa muscolare del petto aumento massa relatività proteine shake whey potensuttryck aumentar tamaño letra macbook air cambiar tamaño imagen online gratis ejercicios para aumentar masa muscular erezione scarsa penispumpe shop per sviluppare i muscoli dieta culturista massa opbouw spiermassa integratori per aumentare massa come creare un pennello con photoshop cs5 alargar su vida en ingles palestra e proteine disfuncion erectil con 18 años crecer pene dieta in massa dietas para masa muscular
