    We attempt to link the momentum dominated and buoyanvy dominated regimes into one relationship by using proposed relations for the transition where:   z/Lb =24/3[(1/2)(x/Lb)2+(Lm/Lb)(x/Lb)]1/3      ...

  • Water Pollution

    Water pollution is a major global problem that requires ongoing evaluation and revision of water resource policy at all levels (from international down to individual aquifers and wells). It has been suggested that it is the leading worldwide cause of deaths and diseases, and that it accounts for the deaths of more than 14,000 people daily. In addition to the acute problems of water pollution in ...

  • Managing oceans with sound science

    Management of marine resources for sustainable development needs local capacity for science, particularly in the Pacific region. Those who care about environmental damage and its effects on the health and welfare of communities tend to focus on land-based threats. That is where harm can be most easily observed, and where its causes — from agricultural pesticides to industrial air ...

  • The Ocean Conference: How the United Nations is addressing ocean health

    Coming up June 5 in New York, the United Nations will bring together stakeholders from around the globe to discuss the health of the world’s oceans. The Ocean Conference will run for five days and will see delegates tackling a host of issues centered on Sustainable Development Goal 14: Conserve and ...

  • How to investigate mercury in the oceans?

    Mercury is a highly toxic metal that affects the environment and can endanger people's health, as a powerful neurotoxin. The combustion of coal, waste and fuel are releasing hundreds of tons of heavy metal into the atmosphere annually, and its sediment enters to soil and water. Mercury measurements are part of the EU project "Global Mercury Observation System". The long-term goal of this ...

  • Shellfisheries: Time to prepare for ocean acidification

    Both physical and social factors must be considered as coastal communities brace for an uncertain future. Oceans are gradually becoming warmer and more acidic as more carbon dioxide enters the atmosphere — two shifts that are altering the economic foundations of many coastal regions. In a ...

  • Will Rio+20 commit to protecting the oceans?

    Promises made at previous summits have not delivered enough protection for the oceans — campaigners are pushing for better results from Rio+20, writes Prime Sarmiento. This month, scientists, campaigners and many developing nations are optimistic they will set in motion a deal on the conservation of the high seas at ...

  • Ocean Acidification: A Litmus Test for International Law

    Ocean acidification, the changing chemistry of the oceans as a result of the absorption of carbon dioxide from the atmosphere, is caused by the atmospheric pollutant that is also the main driver of anthropogenic climate change, having effects on the marine environment as serious as other pollutants entering the oceans. However there is no discernible pressure for a new regime to address the ...

  • Plastic as a Persistent Marine Pollutant

    Abstract Synthetic organic polymers—or plastics—did not enter widespread use until the 1950s. By 2015, global production had increased to 322 million metric tons (Mt) year−1, which approaches the total weight of the human population produced in plastic every year. Approximately half is used for packaging and other disposables, 40% of plastic waste is not accounted ...

  • Ocean science for sustainable development: Facts and figures

    Sarah Grimes explores why we need good ocean monitoring, how to get it, and why it still fails Small Island Developing States. Oceans are a critically important component of the Earth system, supporting ecosystem and human health. They regulate the weather and climate; are essential for producing freshwater; and soak up ...

  • Lead from gasoline discovered in Indian Ocean

    Levels began to climb in the 1970s, peaking a decade ago — a timeline consistent with the region’s pattern of leaded gasoline use. Written by Jennifer Chu, MIT News Office.You can read the original new in MIT NewsSince the 1970s, leaded gasoline has been slowly phased out ...

  • What will it take to get plastics out of the ocean?

    From drones to filters to artificial islands, innovators are working to reduce the threat thousands of tons of trash pose to marine ecosystems. A few palm trees stand strong in the salty breeze. Located on the southern tip of the Pacific island chain of Hawaii, Kamilo Beach is an isolated stretch of black volcanic shoreline in the middle of nowhere. Just a few hundred yards ...

  • Managing multimedia pollution for a multimedia world

    Due to climate-change-induced melting of essential sea ice habitat and a lack of effective regulatory mechanisms to mitigate further losses, the U.S. Fish and Wildlife Service is now considering the polar bear for listing as a threatened species. If we could place ourselves for a moment in one potential future of the polar bear, similarly stranded in the Arctic Ocean on the last tenuous piece of ...

  • In the depths of the oceans, human activities are beginning to take their toll

    Once seen as too remote to harm, the deep sea is facing new pressures from mining, pollution, overfishing and more. Imagine sinking into the deepest parts of the Central Pacific Ocean, somewhere between Mexico and Hawaii. Watch as the water turns from clear to blue to dark blue to black. And then continue on for another 15,000 feet (4,600 meters) to the seafloor — roughly the ...

  • Surface Ocean Acidification studies using Ships Of Opportunity

    Ships of Opportunity Ships of opportunity (SOOP) are used as a platform for cost-efficient collection of environmental data, Ferrybox. The SOOP network operated by NIVA cover the majority of the Norwegian coastline (from Germany (54N ) in the South to Svalbard (78N) in the North. This network is used in the national OA monitoring program. Globally, SOOPs are used for pCO2 measurements and ...

  • Why Pacific islands should take on ocean monitoring

    Pacific islands must build capacity for their own environmental monitoring to tackle both local and global problems, says Ben Ponia. Small island developing states are viewed as the early-warning canary for global environmental change. But though they share global problems, many have an eye for economic growth and have become industrialised nations facing their own suite of home-grown ...

  • “We continue to be stunned at how rapidly the ocean is warming.”

    Oceans have been absorbing more of global warming’s heat and energy than would normally be expected, helping to slow rates of warming on land. But how long will that last? Probing a blue abyss can be an abysmal recipe for the blues. For every 10 joules of energy that our greenhouse gas pollution traps here on Earth, about 9 of them end up in an ocean. ...

  • Why degraded reefs could be the future of ocean conservation

    When there’s not enough pristine habitat left to save an ecosystem, it’s time to take a new look at less-than-perfect places. When you think of a nature preserve, chances are you picture a tract of pristine, healthy wilderness, set aside in order to protect a functioning ecosystem. But what if not much remains of the ecosystem you want to protect? A new proposal by an ...
