  • 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 ...

  • Ocean carbon: A dent in the iron hypothesis

    Oceanographers Jim Bishop and Todd Wood of the U.S. Department of Energy’s Lawrence Berkeley National Laboratory have measured the fate of carbon particles originating in plankton blooms in the Southern Ocean, using data that deep-diving Carbon Explorer floats collected around the clock for well over a year. Their study reveals that most of the carbon from lush plankton blooms never reaches the ...

  • 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 ...

  • 2014 JRC Ocean Energy Status Report

    Abstract Oceans and seas have the potential to play a significant role in providing clean energy. Different technologies are currently being developed to ensure a long term contribution of ocean energy to the future energy system. Among the different ocean energy technologies, tidal and wave conversion systems are expected to contribute the most to the European energy system in the short ...

  • 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 ...

  • Time to stop losing ocean data to vandalism

    More must be done to prevent damage of ocean data buoys that costs money, vital data — and lives, say Sidney Thurston and M. Ravichandran. The global community relies on a rapidly expanding ocean observing network to understand the climate and ecosystems, to help warn against ocean-borne hazards such as tsunamis and storm surges caused by cyclones, and to support sea rescue ...

  • El Niño/La Niña Update: Current Situation and outlook

    Despite warming of the Tropical Pacific Ocean up until June, the overlaying atmosphere largely failed to respond. As a result, ocean temperature anomalies along the equator have decreased over the past two months. Changes in the wind patterns in early-August brought some weak re-warming, but winds have now returned to near normal in the western Pacific, while the pattern of cloudiness has ...

  • Overview of Infrastructure Asset Management A View from Both Sides of the Atlantic Ocean

    AbstractEurope and the United Kingdom (UK) are at the forefront of Asset Management for water utilities. This is primarily due to the fact of privatization of water utilities in the UK. The UK is currently in the third generation of the Asset Management procedures and has well defined methods for identifying and managing assets. In the United Kingdom (UK), large scale Asset Management has been ...

  • 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 ...

  • New monitoring technology helps reveal Arctic secrets

    A group of Arctic researchers has employed the latest monitoring technology to investigate the effects of climate change, by measuring temperature and salinity in the water column beneath surface ice. The results of the investigation, which utilised YSI’s new 'Castaway-CTD', could cast new light on our understanding of the ways in which shifting ocean currents impact upon the climate in ...

  • Case Study: Glastonbury Festival - Noise Monitoring At Glastonbury Festival

    In 1970, an entrance fee of just 1.00 would have permitted you, and about another 1500 'free spirits' to enjoy a weekend of listening to the likes of Quintessence, Marc Bolan and T-Rex, while at the same time savouring the undoubted 'delights' of free raw milk!! Almost three decades later, and at slightly greater expense, you and over 100,000 other people can now enjoy the delights and unique ...

  • Marine Sciences Investigations in Support of Level Oftreatment Decisions for Municipal Wastewater Discharges in Puerto Rico

    ABSTRACT The Puerto Rico Aqueduct and Sewer Authority (PRASA) currently has National Pollutant Discharge Elimination System (NPDES) permits that incorporate relaxation (waiver) of BOD and TSS secondary treatment requirements for six of its regional wastewater treatment plants. The waivers are available under Section 301(h) of the Clean Water Act. Maintaining the waivers requires, in part, ...

  • Marine specimen banking: archive and pollution control for the 21st century

    The oceans have in the past been extensively used as disposal sites for various kinds of waste. The world ocean – being the final sink for many natural and anthropogenic substances – is a "labile" ecosystem, which is and has for a long time been the focal point of extensive interdisciplinary research. Measurements of heavy metals and a suite of various chemical compounds in the marine ...

  • Abrupt Impacts of Climate Change: Anticipating Surprises

    Both abrupt changes in the physical climate system and steady changes in climate that can trigger abrupt changes in other physical, biological, and human systems present possible threats to nature and society. Abrupt change is already underway in some systems, and large scientific uncertainties about the likelihood of other abrupt changes highlight the need for further research. However, with ...

  • Radioactive waste buried beneath Runit Dome on Enewetak Atoll, Marshall Islands

    In the early 1970s after extensive characterisation of fallout the US Pacific Proving Grounds located at Enewetak Atoll began rehabilitation in preparation for the return of indigenous people who were relocated during the Cold War. Cleanup entailed removal and collection of ∼545 GBq of contaminated topsoil, vegetation, and debris (concrete and metal) that was subsequently entombed within an ...

  • Interviews: Ken Buesseler, Researcher into marine discharges at Fukushima

    We as scientists do have a responsibility and I hope to be able to contribute in some way“ Ken Buesseler, researcher at the Wood Hoods Oceanographic Institute is investigating the radioactivity leaked from the Fukushima nuclear power station, initially from data facilitated by the TEPCO (Tokyo Electric Power Company) and then from samples gathered in situ. He believes that official bodies ...

  • 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 ...

  • Is there mercury in your industrial wastewater discharge?

    An assessment of sampling locations for three industrial wastewater effluent piping systems is presented. The assessments provided demonstrate that by installing sampling ports at the appropriate location along an effluent stream’s piping system, truly representative samples can be collected. These real and accurate results scientifically prove that a specific industrial wastewater ...
