  • `Standards are desperately needed for plastic and pesticide contamination in soil´

    In addition to plastic in the oceans, plastic contamination in arable land throughout Europe and other parts of the world is a growing problem. No standards exist for these types of soil pollutants, nor for pesticide residues or their degradation products. For this reason, Professor Violette Geissen is calling for standards to be implemented. On 15 June, Geissen will deliver her inaugural address ...

  • Canarina DESCAR software · ocean pollution modeling · algorithms 4

    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      ...

  • 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.

  • Worldwide Coastal and Oceans Woes Continue.

    'The oceans are in trouble and so are we,' oceanographer Sylvia Earle, National Geographic explorer in residence and researcher for the Smithsonian, was quoted as saying in an article on the web by Seth Borenstein writing for the Philadelphia Inquirer and San Jose Mercury News Washington Bureaus. Citing a study by the Harvard Medical School's Center for Health and the Global Environment covering ...


  • Ocean Thermal Energy and Water Production

    Introduction The scarcity of potable water is a growing problem worldwide, particularly in arid regions and among developing countries. Compounding this problem is the increasing contamination of freshwater sources, which comprise only about 2.5% of all water on Earth. Of this small portion, only 0.5% of the total fresh water available is found in easily accessible sources such as ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...
