Our living planet is only as healthy as its oceans. These vast bodies of water cover more than two-thirds of Earth’s surface and are home to some of our most spectacular and treasured life. Oceans regulate our climate, produce half the oxygen we breathe, fuel the water cycle that produces rain and freshwater, sustain the livelihoods of millions, and provide nourishment for nearly 3 billion people. SOA has the largest ocean youth network in the world, with members in 50 countries. SOA builds a global coalition of ocean champions to tackle ambitious sustainability initiatives for the betterment of our troubled seas. The mid-ocean ridges of the world are connected and form a single global mid-oceanic ridge system that is part of every ocean and the longest mountain range in the world. The continuous mountain range is 65,000 km (40,000 mi) long (several times longer than the Andes, the longest continental mountain range).[28] Scientists surveying an ocean area targeted for deep-sea mining have shown how much is left to discover about the biodiversity of the Clarion-Clipperton Zone, a five-million-square-kilometre region in the central Pacific Ocean. Professor Richard Twitchett explains what a more acidic ocean could mean for the future of marine life. SeaSee App shows us what the world would look like if the oceans were drained of water, using bathymetric (seafloor depth) data to generate 3D views. This app allows you to explore the ocean floor, from shipwrecks to marine habitats. Equipped with a towering rig and the latest in drilling gear, the vessel was designed to reach down through the deep, dark waters to a source of incredible wealth lying on the ocean floor. Although Earth is the only known planet with large stable bodies of liquid water on its surface and the only one in the Solar System, other celestial bodies are thought to have large oceans.[59] 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. 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. Esri and our partners help you build a location strategy and meet your ocean management goals. 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. 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 Call of the Ocean.

The MapShare site shows the progress of someone tracking with an inReach satellite communicator. Read messages they have sent to MapShare. You can even reply. The fish themselves may be different species each year, brought from a different part of the ocean. Esri and our partners help you build a location strategy and meet your ocean management goals. Veteran oceanographer Eddy Carmack has witnessed five decades of accelerating change in the Arctic. As he accepted a lifetime achievement award in January, he talks about why ‘pan-Arctic’ research that crosses borders and disciplines is now imperative.about 2 months ago It is often stated that the thermohaline circulation is the primary reason that the climate of Western Europe is so temperate. An alternate hypothesis claims that this is largely incorrect, and that Europe is warm mostly because it lies downwind of an ocean basin, and because atmospheric waves bring warm air north from the subtropics.[39][40] 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] Not enough is known of the larger trans-Neptunian objects to determine whether they are differentiated bodies capable of supporting oceans, although models of radioactive decay suggest that Pluto,[69] Eris, Sedna, and Orcus have oceans beneath solid icy crusts approximately 100 to 180 km thick.[66] The total mass of the hydrosphere is about 1.4 quintillion metric tons (7018140000000000000♠1.4×1018 long tons or 7018150000000000000♠1.5×1018 short tons), which is about 0.023% of Earth’s total mass. Less than 3% is freshwater; the rest is saltwater, almost all of which is in the ocean. The area of the World Ocean is about 361.9 million square kilometers (139.7 million square miles),[9] which covers about 70.9% of Earth’s surface, and its volume is approximately 1.335 billion cubic kilometers (320.3 million cubic miles).[9] This can be thought of as a cube of water with an edge length of 1,101 kilometers (684 mi). Its average depth is about 3,688 meters (12,100 ft),[9] and its maximum depth is 10,994 meters (6.831 mi) at the Mariana Trench.[29] Nearly half of the world’s marine waters are over 3,000 meters (9,800 ft) deep.[16] The vast expanses of deep ocean (anything below 200 meters or 660 feet) cover about 66% of Earth’s surface.[30] This does not include seas not connected to the World Ocean, such as the Caspian Sea. 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. Five men were floating about in a boat in the Southern ocean. It looks like a fish, moves like a fish, but it’s definitely a robot. It’s name is SoFi (short for soft robotic fish), and according to its creators at MIT’s computer science and AI lab CSAIL, it’s the most versatile bot of its kind. And with its built-in cameras, scientists should be able to use SoFi to get close to the ocean’s inhabitants without spooking them — hopefully giving us greater insight into the lives of under-observed sea creatures. The ocean covers more than two-thirds of our planet, and there’s so much of it left unexplored. How are we humans supposed to blend in to uncover all of its secrets, when our observation tools are hooked to clunky vehicles with fish-scaring propellers and jets? Oceana Canada, an ocean research charity, is hoping citizen scientists in Halifax armed with DNA kits will help them sniff out seafood fraud. Despite making up more than 70% of the Earth’s surface, there is still much about the oceans that we do not know. 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. The United Nations has proclaimed a Decade of Ocean Science for Sustainable Development (2021-2030) to gather ocean stakeholders worldwide behind a common framework that will ensure ocean science can fully support countries in the achievement of the Sustainable Development Goal 14 on the ocean. The Nintendo controller speaks to the fish by sending vibrations through the ocean at frequencies higher than humans can hear. These pulses are essentially commands translated into binary code (or perhaps Morse code), which the robo-fish can read despite the background vibrations of the ocean. The researchers tested their creation out in the Pacific Ocean, at depths from zero to 18 meters (59 feet), according to the study published today in Science Robotics. pastiglie per allungare il pene costruzione massa muscolare gute potenzmittel quali proteine assumere per aumentare la massa muscolare dieta per la massa muscolare proteine fitness integratori per rinforzare i muscoli como alargar pene de forma natural l arginin 1000 mg masa muscular kiwi alimenti che fanno crescere i muscoli pastilla para la ereccion duradera aumentar gluteos ejercicios en casa eiaculazione veloce come risolvere eiaculazione precoce como alargar su pene top proteinas para aumentar masa muscular alimentazione massa invernale erezione immediata comment faire prendre du poids a un chien como lacear calçados de couro aumentare massa proteine proteine musculation a 16 ans ganar musculo en los brazos come incrementare la massa muscolare i migliori integratori per la massa tecnicas naturales para agrandar el miembro gratis allungamento molla moto armonico esercizi stretching colonna vertebrale alargador 4mm espiral
