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. What is it like to stand on the ocean floor? What do you learn from a lifetime spent in the heart of the sea?  Lanternfish are one of many animals that light up the ocean with their glowing bodies. In the broad pathways of the ocean such a chance is doubtful. Michael Lodge admits that but also argues that the areas affected will be tiny compared with the vastness of the oceans – “much less than half a per cent” – and that big areas have been earmarked as reserves to be left untouched. To put into perspective just how deep the oceans go, created the illustration below (click the image for a larger version). In addition, many land animals have adapted to living a major part of their life on the oceans. For instance, seabirds are a diverse group of birds that have adapted to a life mainly on the oceans. They feed on marine animals and spend most of their lifetime on water, many only going on land for breeding. Other birds that have adapted to oceans as their living space are penguins, seagulls and pelicans. Seven species of turtles, the sea turtles, also spend most of their time in the oceans. As the world ocean is the principal component of Earth’s hydrosphere, it is integral to life, forms part of the carbon cycle, and influences climate and weather patterns. The world ocean is the habitat of 230,000 known species, but because much of it is unexplored, the number of species that exist in the ocean is much larger, possibly over two million.[10] The origin of Earth’s oceans is unknown; oceans are thought to have formed in the Hadean eon and may have been the impetus for the emergence of life. The Mars ocean hypothesis suggests that nearly a third of the surface of Mars was once covered by water, though the water on Mars is no longer oceanic (much of it residing in the ice caps). The possibility continues to be studied along with reasons for their apparent disappearance. Astronomers think that Venus had liquid water and perhaps oceans in its very early history.[citation needed] If they existed, all later vanished via resurfacing. Scientists have just defined the newly named rariphotic zone, a layer of ocean between depths of 130 and 300 metres (400 and 1,000 feet) – a low-light or “twilight zone” in deeper reef regions. Thank the ocean with every breath you take, says Dr Sylvia Earle To put into perspective just how deep the oceans go, created the illustration below (click the image for a larger version). Scientists designed SoFi to solve several problems that bedevil oceanic robotics. Problem one: communication. Underwater vehicles are typically tethered to a boat because radio waves don’t do well in water. What SoFi’s inventors have opted for instead is sound. The XPRIZE Ocean Initiative is dedicated to ensuring our ocean is healthy, valued and understood. Together we’re building an online community for people to share ideas, collaborate, and invent technology that could help keep our oceans healthy. Zdaniem naukowców wielkość oceanu jest zbliżona do amerykańskiego Lake Superior, czyli drugiego największego jeziora na Ziemi.  Despite making up more than 70% of the Earth’s surface, there is still much about the oceans that we do not know. The world’s oceans are a lifeline for people around the world, generating at least $2.5 trillion worth of products and services each year. Fishing alone supports more than 260 million jobs. Only a healthy ocean can keep this economic engine running. 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] A wealth of ocean data has been and is being collected. Many of the datasets are open, yet very few are being used for resource management, business, or conservation. Most businesses, let alone individuals, do not have the time or ability to translate ocean data into actionable information, yet large industries and millions of people rely on the ocean for their livelihoods and well-being. So long as ocean data remain disconnected from services that people and markets can use, we will be unable to engage the numbers of actors needed to address critical ocean challenges. Data collection is not evenly distributed across the ocean — some regions are in need of data acquisition, a need that could be addressed through the development of demand for data services, which will in turn drive demand for data collection tools. Overall, there is a market failure for meaningful data services, and the time is ripe for market development. Lanternfish are one of many animals that light up the ocean with their glowing bodies. 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. 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. 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. Ta rozmowa jest jak życie, raz płynie jak wartka rzeka, innym razem powolutku – delikatnie zaczepiając o problematyczne skałki a czasem zupełnie jak wzburzony ocean. Jestem naprawdę zauroczona osobowością, pozytywnym nastawieniem i otwartością Pani Julii 🙂 Fantastyczna książka. Gorąco polecam! 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 to learn why a healthier ocean means a healthier planet, and find out how you can help. “It’s estimated that 95 percent of the livable space on our planet is in the ocean, yet only a fraction of that space has been explored,” said study lead author Carole Baldwin of the NMNH. 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. An expert in underwater filming, Orla Doherty is one of the lucky few to have explored the deepest parts of the ocean. The XPRIZE Ocean Initiative is dedicated to ensuring our ocean is healthy, valued and understood. Oceana Canada, an ocean research charity, is hoping citizen scientists in Halifax armed with DNA kits will help them sniff out seafood fraud. (Elaine Thompson/Associated Press) 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. como se dice agrandar en inglés cosas para aumentar masa muscular integratori per gonfiare i muscoli licuados para aumentar la masa muscular mettere massa muscolare alimentazione come farsi allungare i capelli uomo arandas tequila bar menu aparatos para engrosar el pene stiramento del pene aumento massa oxandrolone masa muscular en un dia i migliori mass gainer erektionsstörungen ursachen junge männer pastillas para alargar el miembro aumentare la massa muscolare e definire integratore creatina taurina migliore lozione anticaduta capelli masa muscular fuerza aumentare massa muscolare adolescenza no me crece el pene como se pueden agrandar los labios naturalmente como hacer para tener un pene grande aumentar la masa muscular en mujeres corsi per extension ciglia torino extension capelli naturali con clips como hacer crecer el pené naturalmente gratis videos esercizi per aumentare massa gambe esercizi per aumentare massa dei pettorali comment faire pousser les cils naturellement grossissement penien
