  • New training and technical guidance on petroleum measurement

    Measurement of the quantity and quality of petroleum and its products is vital for accurate allocation, custody transfer and fiscal purposes, stock control and loss prevention. The Energy Institute (EI)'s Hydrocarbon Management Committee (HMC) has developed new online training and good practice guidance to support greater understanding in this field. This new resource, ...

  • Scientific sub makes deep-sea discoveries

    The collaborative voyage of US and Australian researchers was led by chief scientists Dr Jess Adkins from the California Institute of Technology and Dr Ron Thresher from CSIRO’s Climate Adaptation and Wealth from Oceans Flagships. “We set out to search for life deeper than any previous voyage in Australian waters,” Dr Thresher says. “We also gathered data to assess the threat posed by ocean ...

  • Trawling threatens to destroy deep-sea ecosystems

    Intensive trawling could turn seafloor ecosystems into ‘deserts of the sea’, new research warns. The study found that continuous bottom trawling for shrimp in a deep-sea Spanish canyon has damaged the foundations of marine ecosystems by dramatically reducing seafloor biodiversity and nutrients in sediment. Increasingly, fishers around the world are taking bottom trawling further, and ...

  • New project to study the impacts of climate change on Arctic ecosystems

    A new project will investigate how climate-driven changes affect two top Arctic predators, the Harp and Ringed seals, as well as the base of the Arctic food web. As part of this project scientists from the National Oceanography Centre (NOC) will work alongside five other UK centres and 21 international partners to help improve understanding of the Arctic, which has been traditionally under ...

  • Monitoring heavy metal contamination in the German Wadden Sea

    Human activities, including industrial development along coastal areas, risk polluting the marine environment with heavy metals which can harm human health and aquatic life. A recent study has found elevated levels of metal pollution in the Jade area of the German Wadden Sea, but concludes that metal contamination of the sediments would not be expected to have harmful effects on the marine ...

  • Ocean floor to be cleaned as part of Tasman Bay biosecurity operation

    MAF Biosecurity New Zealand (MAFBNZ) is arranging to dredge an area of seabed in Tasman Bay early next week to reduce the risk posed by marine organisms that fell on the ocean floor during the cleaning of an oil rig there late last year. The rig, the Ocean Patriot, had been directed to remove biofouling species that had been listed as potential pests (including New Zealand's green shell mussel) ...

  • Banned contaminants can persist in environment for decades

    The contamination of hazardous substances in estuaries can have negative effects on biodiversity. Using experimentally supported indicators, this study analysed the environmental risks posed by 22 different contaminants in UK estuaries and coastal waters, finding that substances banned over 20 years ago continue to persist in the marine environment. Estuaries, where rivers meet the sea, are home ...

  • Snake robot on Mars?

    So far, NASA has landed four rovers on Mars. These are solar-powered robots with six wheels and robotic arms that can take soil samples and operate cameras. Sojourner landed in 1997, Spirit and Opportunity in 2003, while the more advanced Curiosity was landed last summer. "Manoeuvrability is a challenge. The Spirit rover was lost after it became stuck in the sand on Mars. The vehicles just cannot ...

  • US and Portugal sign agreement for climate research collaboration

    The United States signed an agreement with Portugal today to launch the installation of a portable climate observatory on Graciosa Island in the Azores.  The mobile observatory will obtain measurements of cloud and aerosol properties from the island’s marine environment for 20 months, beginning in May.  The measurements are expected to greatly enhance scientific understanding of the ...

  • UN licences kick off search for underwater minerals

    The International Seabed Authority (ISA) has begun issuing exploration licences for mining the yet untouched floor of international waters raising concerns about potential environmental impacts. The licenses, issued on 21 July, grant prospecting rights for underwater minerals to private and state-owned companies from Brazil, Cook Islands, ...

  • Hanovia launches new UV transmittance analyser for water disinfection monitoring

    The new TX Online UV transmittance analyser from Hanovia has been specifically designed to provide accurate monitoring of UV water disinfection systems in the food and beverage, brewing, pharmaceutical, electronics, aquaculture and marine (ballast water treatment) industries. The TX Online's one-piece design allows simple mounting and uses minimal space. Its new optics provide increased accuracy ...

  • Unmixing Analysis: A Powerful Forensics Tool for Source Identification and Allocation

    Integral scientists have developed software to apply a powerful but rarely used numerical technique to environmental investigations, in ways that provide a robust quantification of potential contributions of chemical sources at contaminated sites. Known as unmixing analysis, this mathematical technique has produced effective results by providing strong lines of evidence for estimating the ...

  • Microalgae sticks to microplastics and transports them to the seabed

    Fragments of microplastics are readily incorporated into groups of microscopic algae, altering the rate at which the plastics move through seawater, a recent study has found. In laboratory tests, polystyrene microbeads, which usually sink to the bottom of seawater at a rate of 4 mm a day, sank at a rate of several hundreds of metres a day when part of microalgae aggregates. Plastic debris litters ...

  • JRC-IRMM releases a new certified reference material for trace elements in shellfish

    JRC-IRMM has released a new certified reference material (CRM) ERM-CE278k Mussel Tissue. Certified values are given for 13 elements that allow laboratories to control analytical measurements made for environmental monitoring and to ensure food safety. Compared to our previous mussel tissue CRMs, it provides ...

  • Mercury Levels in Humans and Fish Regularly Exceed Health Advisory Levels Worldwide

    A new scientific report finds that humans and marine ecosystems around the world are contaminated with mercury and that mercury levels in humans and fish regularly exceed health advisory guidelines. The report, a collaboration between IPEN and Biodiversity Research Institute (BRI), highlights the urgent need for an overall reduction in mercury emissions when government delegates convene next week ...

  • SEAL Analytical appoints UK Sales Manager

  • FlowCAM for SAMS

    A Fluid Imaging FlowCAM has been supplied to the Scottish Association for Marine Science by Planet Ocean (UK). The instrument can rapidly monitor particles in fluid, combining the capabilities of cytometry and microscopy, providing an order of magnitude improvement over each. Instantly, the cells in a discrete sample or a continuous flow are counted, analysed and imaged. The processing system ...


  • The risks of CO2 leakage through submarine ‘chimneys’

    NOC scientists are playing a key role investigating the risks of leaks from carbon dioxide (CO2) storage reservoirs situated under the seabed. Researchers from the National Oceanography Centre (NOC) will work with academics at the University of Southampton, who are leading the project, and the University of Edinburgh to better understand the risks involved in the storage of CO2 in depleted oil ...

  • Oceanographers discover toxic algae

    Louisiana State University, USA, researchers Sibel Bargu and Ana Garcia (Department of Oceanography and Coastal Sciences) have discovered toxic algae in vast, remote regions of the open ocean for the first time. The recent findings are published in the Proceedings of the National Academy of Sciences (PNAS). Harmful algal blooms (HABs) are reported as increasing both geographically and in ...


  • European Space Agency contributes to ocean carbon cycle research

    The Earth’s oceans play a vital role in the carbon cycle, making it imperative that we understand marine biological activity enough to predict how our planet will react to the extra 25,000 million tonnes of carbon dioxide humans are pumping into the atmosphere annually. The colour of oceanic seawater depends largely on the number of microscopic phytoplankton, marine plants that live in the ...
