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. 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. Charles Moore, who first sailed the so-called Great Pacific Garbage Patch in 1997, has returned five times over 15 years to document the concentrations of plastic in the ocean. His results show microplastics are accumulating at a rapid rate.about 1 month ago New studies show complex effects of carbon dioxide on fish population. Many studies have shown that larvae of various fish species can be negatively affected by ocean acidification. Acidification is caused by large amounts of carbon dioxide (CO2) entering the seawater from the atmosphere. But CO2 can also influence the food supply for the fish … more 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] The Ocean Cleanup is pleased to announce Lonneke Holierhoek has joined the organization as Chief Operations Officer, taking on the challenge of managing the development of The Ocean Cleanup’s technology towards execution.  In 2018 The Ocean Cleanup is set to deploy its very first ocean cleanup system in the North Pacific… Ocean (łac. Oceanus, stgr. Ὠκεανός Okeanos – u starożytnych Greków i Rzymian mityczna rzeka oblewająca cały świat, także nazwa jej boga) [1] – wielka część hydrosfery ziemskiej, stanowiąca rozległy obszar słonej wody. Wody słone pokrywają w sumie blisko 3/4 (70,8%) Ziemi. Powierzchnia oceanów wynosi ok. 361 mln km², a ich łączna objętość ok. 1,3•1018 m³. email : biuro@karchercenter-ocean.pl We give youth access to high-level conversation and a platform to showcase their ideas and solutions that can protect our ocean. We foster the entrepreneurial spirit of our members and challenge them to design creative policy and business solutions. SOA currently supports over 160 youth-led sustainability projects around the globe. In the center of the Pacific Ocean gyre our researchers found more plastic than plankton. A Plastic Ocean documents the newest science, proving how plastics, once they enter the oceans, break up into small particulates that enter the food chain where they attract toxins like a magnet. These toxins are stored in seafood’s fatty tissues, and eventually consumed by us. The Big Ocean Button Challenge is a $100,000 app development competition to turn ocean data, into the products and services we need. But today, Pardo’s vision is becoming reality as the UN’s International Seabed Authority has drawn up maps dividing the ocean into blocks. 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. As mandated by the UN General Assembly, the Intergovernmental Oceanographic Commission (IOC) of UNESCO will coordinate the Decade’s preparatory process, inviting the global ocean community to plan for the next ten years in ocean science and technology to deliver, together, the ocean we need for the future we want! When you purchase the 4Ocean Signature Blue and Limited Edition Coral Reef Bracelets, we will remove two pounds of trash from the ocean and coastlines and also help to restore and regrow coral reefs through our partnership with the Coral Restoration Foundation*. These bracelets represent your support. Lanternfish are one of many animals that light up the ocean with their glowing bodies. 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] Please reach out to UNESCO’s IOC via oceandecade@unesco.org Together we’re building an online community for people to share ideas, collaborate, and invent technology that could help keep our oceans healthy. Ocean & Coastal Management is an international journal published 12 times per year dedicated to the study of all aspects of ocean and coastal management at international, national, regional, and local levels. Our oceans have absorbed most of the planet’s warming—over 90%—and a significant amount of our carbon pollution. Warmer oceans are driving stronger storms and bleaching coral reefs. As oceans absorb carbon dioxide, they become more acidic, threatening most shelled organisms, including small crustaceans fundamental to the marine food chain. Some planets and natural satellites outside the Solar System are likely to have oceans, including possible water ocean planets similar to Earth in the habitable zone or “liquid-water belt”. The detection of oceans, even through the spectroscopy method, however is likely extremely difficult and inconclusive. 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. Oregon’s year-round fishing spans the state from native redband trout in eastern deserts to rockfish and halibut in ocean waters – with lots of salmon, steelhead, trout and warmwater fishing in between. Whether your plans take you to a nearby neighborhood pond or to one of the state’s premiere fishing destinations, there will be a place for you to fish in Oregon every day of the year. ©2018 Ocean.io · 1A, Heienhaff · L-1736 Senningerberg · Luxembourg · hello@ocean.io 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 Soft Robotic Fish, aka SoFi, is a hypnotic machine, the likes of which the sea has never seen before. In a paper published today in Science Robotics, MIT researchers detail the evolution of the world’s strangest fish, and describe how it could be a potentially powerful tool for scientists to study ocean life. “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.
