  • Bioavailability of purified subcellular metals to a marine fish

    In this study, we took advantages of the supply of naturally contaminated oysters and investigated how the subcellular metal distribution and the metal burden in prey affected the transfer of metals to a marine fish, the grunt Terapon jarbua. The oysters Crassostrea hongkongensis with different contaminated histories were collected and separated into three subcellular fractions (metal‐rich ...

  • Marine Snow Storms: Assessing the environmental risks of ocean fertilization

    The threats posed by climate change to the global environment have fostered heightened scientific and commercial interest in marine geo-engineering schemes designed to boost the capacity of the oceans to absorb atmospheric carbon dioxide. This is the primary goal of a process known as ocean fertilization, which seeks to increase the production of organic material in the surface ocean in order to ...

  • Sunscreen’s Dark Side

    In 2013, more than 200 million tourists sunbathed on Mediterranean beaches. You can bet that most of them applied sunscreen. That sunscreen may be valuable for preventing skin cancer for humans, but it can also wreak havoc on marine ecosystems. A new study published in Environmental ...

  • 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 ...

  • Ocean acidification investigations in the Kiel Fjord

    Continuous, reliableand direct pCO2measurements since 2012 Greenhouse gases, and in particular carbon dioxide (CO2), are one of the most discussed topics in society today, influencing political debate, legal framework and business decision-making. From a pre-industrial 280ppm, atmospheric CO2 has risen to a present-day level of 390ppm, with this figure expected to rise to up to 1000ppm by the ...

  • Auto mechanics find new way to save the environment and money

    Some mechanics have reported a 50% savings in cleaning time by turning to an ultrasonic parts cleaning machine while taking advantage of an ecologically safe alternative to manual cleaning with toxic chemicals. With today's industrial sized ultrasonic cleaners, the speed of ultrasonic cleaning to remove soils is combined with the capacity to clean multiple parts at once. Let's take a look at some ...

  • Valuing Plastic – The Case for Business Action

    Concern is growing over the threat that widespread plastic waste poses to marine life, with conservative estimates of the overall financial damage of plastics to marine ecosystems standing at US$13 billion each year, according to two reports released last week at the first United Nations Environment Assembly. The eleventh edition of the United Nations Environment Programme (UNEP) Year Book looks ...

  • Electrocoagulation and nanofiltration integrated process application in purification of bilge water using response surface methodology

    Marine pollution has been considered an increasing problem because of the increase in sea transportation day by day. Therefore, a large volume of bilge water which contains petroleum, oil and hydrocarbons in high concentrations is generated from all types of ships. In this study, treatment of bilge water by electrocoagulation/electroflotation and nanofiltration integrated process is ...

  • Environmental impacts of ocean-energy systems: a life-cycle assessment

    Ocean-energy technologies — which harvest renewable energy from the sea — will have a significant role to play in a future low-carbon society. A recent life-cycle analysis of different ocean-energy devices has found that life-cycle environmental impacts are caused mainly by the materials used in the mooring, foundations and structures. Improving the efficiency and lifespan of the ...

  • Seeding the oceans may not stop climate change

    Geo-engineering against climate change – Seeding the oceans with iron may not address carbon emissions Numerous geo-engineering schemes have been suggested as possible ways to reduce levels of the greenhouse gas carbon dioxide in the atmosphere and so reduce the risk of global warming and climate change. One such technology involves dispersing large quantities of iron salts in the oceans to ...

  • The number one thing we can do to protect Earth’s oceans

    Marine governance favors consumption and commerce over conservation. Here's what we can do about it. When New England fishers complained of working harder and harder to catch fewer and fewer fish, Spencer Baird assembled a scientific team to investigate. Though a fishery failure would once have seemed inconceivable, Baird wrote in his report, “an alarming decrease of the ...

  • Pacific lessons on research engagement and impact

    The University of the South Pacific's massive catchment may mean less research cash, but its science helps the region, reports Anne Moorhead. The University of the South Pacific, known locally as USP, is one of just two regional universities in the world: the other is the University of theWest Indies. Serving the academic and research needs of 12 small island countries spread over ...

  • OSE II economic comparison to dispersants and mechanical Clean ups

    INTRODUCTION   Oil Spill Eater II is the name of a non-toxic product which provides the means for moving oil spill response out of its 19th Century methodology into the realm of advanced technological 21st Century breakthroughs for addressing and remediating 100% of any spill in any environment. In comparison, current response methods employed by three major oil companies - BP, Exxon ...

  • Safe and efficient oil-platform removal

    Safe and efficient oil-platform removal Aker Marine Contractors (AMC) has developed a new method of removing offshore platforms to meet international decommissioning guidelines. Trelleborg Viking supplied rubber elements for the AMC buoyancy tank assemblies. Safe and efficient oil-platform removalWhat happens to an offshore oil platform when all the oil has been ...


  • “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. ...

  • Case study - Public-private partnership successfully tests leakwise early oil spill detection sensor in the tidal Delaware river

    Background In the summer of 2011, the Delaware River Basin Commission (DRBC) and the U.S. Geological Survey (USGS) collaborated with GE Analytical Instruments on a unique test deployment of an oil sheen sensor in the tidal Delaware River. The idea for the test deployment arose during meetings of the Delaware River and Bay Oil Spill Advisory Committee, which includes organizations and ...

  • How to choose the most cost-effective methods for improving water quality

    Agricultural run-off can contain pesticides, sediment particles and nitrates and is a major threat to the health of the sea. Although there are policy frameworks to reduce run-off water, they often don’t clearly explain how to maximise benefits. A new study provides an economic framework that prioritises methods based on their cost-effectiveness, which could help policymakers to reduce the ...

  • How we can save coral reefs (and why we should want to)

    As oceans grow warmer and more acidic, scientists are developing new strategies to rescue the “rainforests of the sea.” Coral reefs are among the most beautiful ecosystems on Earth — “a jeweled belt around the middle of the planet,” in oceanographer Sylvia Earle’s words. They also are extremely valuable. Reefs cover less than one-tenth of 1 percent of ...
