  • Small RNAs yield great amounts of data from ocean microbe samples

    An ingenious new method of obtaining marine microbe samples while preserving the microbes' natural gene expression has yielded an unexpected boon: the presence of many varieties of small RNAs -- snippets of RNA that act as switches to regulate gene expression in these single-celled creatures. Before now, small RNA could only be studied in lab-cultured microorganisms; the discovery of its presence ...

  • Ocean pH value decreasing

    A research project into ocean acidification has increased knowledge about conditions in the Baltic Sea and Kattegat-Skagerrak. When the pH value falls, the whole marine ecosystem is affected. A newly developed measurement technique provides information about natural variations in the oceans, which results in improved environmental monitoring. Since 1850 the pH value of the world’s ...

  • Tracing CO2 elements in the ocean

    The surface waters of the vast Southern Ocean are suffering from 'marine anaemia' – a serious deficiency in the micronutrient iron. Just as iron deficiency negatively affects the health and productivity of humans and other land-based creatures, so it affects the phytoplankton (microscopic marine plants) existing in the oceanic realm. The environmental consequences of this condition restrict ...

  • Microplastics discovered in the deep, open ocean

    A unique study by scientists at the National Oceanography Centre (NOC) will provide valuable new insights into the concentrations of microplastics in the open ocean from surface to the sea bed. Professor Richard Lampitt and Dr Katsia Pabortsava, who lead microplastic research at NOC, said “There is considerable uncertainty about the concentration and characteristics of the many ...

  • Team probes mysteries of oceanic bacteria

    Microbes living in the oceans play a critical role in regulating Earth's environment, but very little is known about their activities and how they work together to help control natural cycles of water, carbon and energy. A team of MIT researchers led by Professors Edward DeLong and Penny Chisholm is trying to change that. Borrowing gene sequencing tools developed for sequencing the human ...

  • Typhoons bury tons of carbon in the oceans

    A single typhoon in Taiwan buries as much carbon in the ocean - in the form of sediment - as all the other rains in that country all year long combined. That's the finding of an Ohio State University study published in a recent issue of the journal Geology. The study - the first ever to examine the chemistry of stream water and sediments that were being washed out to sea while a typhoon was ...


  • Ocean research drives growth for SEAL Analytical

    Business is booming in the UK for SEAL Analytical, the manufacturer of the AA3HR and QuAAtro automated segmented flow laboratory analyzers. Explaining the recent upturn in business, EMEA Sales Manager Haydon Warner says: “Automated testing of large numbers of samples at very low levels of analysis has been the main driver. Our team of application chemists and engineers are constantly ...

  • China Ocean Energy Power Generation Market Analysis

    China ocean energy power generation market analysis is an invaluable asset for anyone who wants to invest in the ocean energy power generation industry, to import into/from China, to build factories in China, to partner with one of the key Chinese corporations, or to compete in the segment. The report provides in-depth analysis and detailed insight into the ocean energy power generation industry, ...


  • European researchers isolate ocean methane-eating microbes

    Researchers from Germany and the US have developed a molecular technique for capturing the microorganisms that are responsible for absorbing 80% of the ocean’s methane (CH4) emissions. The team has since isolated the genes that are involved in taking up the gas. Unbeknownst to many, there are more than 100 million times more micro-organisms in the ocean than there are stars in the visible ...

  • Indian Ocean pirates impede climate observations

    Australian scientists have sought the help of the United States and Australian navies to plug a critical gap in their Argo ocean and climate monitoring program caused by Somali pirates operating in the western Indian Ocean. "We have not been able to seed about one quarter of the Indian Ocean since the increase in the piracy and that has implications for understanding a region of ...

  • Greenhouse Gas CO2 Sidetracked in Oceans` Twilight Zone

    WOODS HOLE, Massachusetts (ENS) - Climate experts have relied on the oceans to absorb enough of the greenhouse gas carbon dioxide to slow global warming, but new research by an international team of scientists shows that the oceans may have little impact on changes in the atmosphere or climate. The research indicates that instead of sinking, carbon dioxide is often consumed by ...

  • Ocean warming detrimental to inshore fish species

    The findings of a study published today in Nature Climate Change indicate negative effects on the growth of a long-lived south-east Australian and New Zealand inshore species – the banded morwong. Scientific monitoring since 1944 by CSIRO at Maria Island, off the east coast of Tasmania, showed that surface water temperatures in the Tasman Sea have risen by nearly 2°C over the past 60 ...

  • Arctic Ocean Ice Thinner By Half in Six Years

    BREMERHAVEN, Germany, September 14, 2007 (ENS) - Large areas of Arctic sea ice are only one meter thick this year, about 50 percent thinner than they were in the year 2001, according to measurements taken by 50 scientists on board the research ship Polarstern. The international team is conducting research on sea ice in the central Arctic Basin.'The ice cover in the North Polar Sea is ...

  • Teledyne Webb Research Awarded Open Ocean Glider Contract for Ocean Observatories Initiative

    Teledyne Webb Research announced today that it has been selected to provide Open Ocean gliders for the Ocean Observatories Initiative (OOI). This award follows closely on the recent award to Teledyne Webb Research of the Coastal Glider program for the OOI. The Open Ocean Slocum G2 gliders will support the high latitude Global Arrays of the OOI. Similar to the Coastal Glider program, this ...


  • 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) ...
