  • CO2-chomping microbes battling for ocean iron

    Research published recently in the Proceedings of the National Academy of Science explores the relationship between iron, which limits primary productivity in vast regions of the ocean, and its uptake by phytoplankton species. It has identified how natural organic compounds in the Southern Ocean can control iron availability to phytoplankton in iron-deficient waters and, in particular, for ...

  • Observing arctic ice-edge plankton blooms from space

    Ongoing climate-driven changes to the Arctic sea-ice could have a significant impact on the blooming of tiny planktonic plants (phytoplankton) with important implications for the Arctic ecosystem, according to new research conducted by scientists at the UK\'s National Oceanography Centre (NOC). Advances in modern satellite technology offer the opportunity to observe and monitor ice-edge blooms at ...


  • 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 ...

  • Chelsea’s expert on active fluorescence techniques presents at Challenger Conference for Marine Science - University of East Anglia (3-5 Sept 12)

    Chelsea Technologies Group will once again be exhibiting and presenting at the Challenger Society for Marine Science Conference & Mini-Expo at the University of East Anglia, 3-5th September. Veronica Chan, one of Chelsea’s experts on active fluorescence techniques, will be presenting a paper entitled "How recent technological advances have enhanced and extended the applications for ...

  • Voyage to Southern Ocean to monitor greenhouse gas air-sea fluxes

    Scientists have set off from the Chilean port of Punta Arenas to spend 42 days amid the high winds and big waves of the Southern Ocean, where they will make groundbreaking measurements to explain how large amounts of climate-affecting gases move between atmosphere and sea, and vice-versa. The cruise should provide important information on factors controlling the flux of the greenhouse gas carbon ...

  • Scientists warn of profound changes in World`s oceans

    Climate change is transforming the world's oceans by increasing the temperature and acidity of seawater, and altering atmospheric and oceanic circulation, reported a panel of scientists this week at the American Association for the Advancement of Science, AAAS, annual meeting in Boston.  'The vastness of our oceans may have engendered a sense of complacency about potential impacts from ...

  • Primary Productivity Monitoring in the Antarctic using CTG FastOcean FRRf System

    Marine photosynthesis is responsible for approximately half the oxygen in our atmosphere. In other words the oxygen in every second breath we take comes from the ocean. For the last 10 years Professor Andrew McMinn and his team from the Institute for Marine and Antarctic Studies, University of Tasmania have been using a Chelsea  ...

  • Geoengineering could worsen climate change

    Geoengineering – which sometimes seems to be the despairing climate scientist’s Plan B – simply won’t work. It won’t offer a quick fix to the planet’s burden of global warming, and it will be difficult to convince anybody that it could work at all. Geoengineering is any deliberate, large-scale intervention in the workings of the climate machine ...

  • Global Weather Report – Extreme weather warning

    New research warns that longer, hotter and more frequent heatwaves than those that killed 55,000 Russians in 2010, or 72,000 in France, Portugal, Italy, the Netherlands, Germany and the UK in 2003, will hit Europe in the next two decades. But, over the same period, Europe could also begin to get colder as a consequence of a drop in solar activity, and a century-long ...
