  • Deep thinking on the world’s oceans

    Changes in deep ocean conditions affect global climate, with deep warming contributing to sea-level rise and the deep ocean absorbing atmospheric carbon dioxide. To assess change, researchers determine the amount of energy (in the form of heat), water and gases (including carbon dioxide), entering and exiting the ocean. They rely on valuable but infrequent deep ocean measurements from ships, ...

  • Little hills have big effect on biodiversity

    New research, published today in Progress in Oceanography by scientists at the NOC and the University of Southampton, show that deep-sea hills increase the biodiversity of forams - a very important group of shelled protozoans. There are over 25 million of these hills on the ocean floor, each hundreds of metres high. They cover around 40% of the ocean floor, making them the dominant landform on ...

  • Ocean fertilization experiment draws fire

    A German research ship laden with 20 tonnes of iron sulphate has whipped up a storm of protest as it sails towards the Antarctic, where it intends to dump its cargo into the ocean. Scientists on thePolarstern, which set sail from Cape Town in South Africa on 7 January, plan an ocean fertilization experiment that some argue will violate international law. But the scientists say that it will ...

  • New Technology for Ocean Acidification Research

    Ocean pH has dropped from approximately 8.2 to 8.1 pH over the past 200 years, representing a 25% increase in acidity. The development of better instruments to measure ocean pH, particularly in the deep ocean, is vital to understanding the magnitude and impact of these changes. High-resolution in-situ measurements of pH in the ocean are now possible with innovative adaptations to ion sensitive ...

  • Onset Announces Deep Ocean Temperature Data Logger

  • Ocean fertilization `fix` for global warming discredited by new research

    Research performed at Stanford and Oregon State Universities suggests that ocean fertilization may not be an effective method of reducing carbon dioxide in the atmosphere, a major contributor to global warming. Ocean fertilization, the process of adding iron or other nutrients to the ocean to cause large algal blooms, has been proposed as a possible solution to global warming because the growing ...

  • It is too early to sell carbon offsets: scientists

    Published January 10 in the journal Science, signatories include scientists from the US, Japan, Hawaii, New Zealand, The Netherlands, India, Germany and the UK. The UK is represented by Prof Andrew Watson of the University of East Anglia and Dr Richard Lampitt of Southampton University's National Oceanography Centre. Prof Watson said: 'While we do envision the possibility of iron fertilisation ...

  • Deep-ocean sentinels on northern climate watch

    Up to 3,000 metres tall and carrying an array of special marine sensors, the moorings were deployed earlier this month as part of an international collaboration to monitor the Timor Passage and Ombai Strait – two strategic deep ocean channels which act as 'chokepoints' in the global system of ocean currents. Valued at over $1 million, the moorings were deployed as part of Australia's ...

  • New ‘seawater’ – the way ahead for ocean science

    A proposed new definition of ‘seawater’ is drawing the attention of the world’s oceanographic community in a change that will advance the accuracy of climate science projections.The science case for a change in the definition of seawater was first agreed to in 2006 when the international guiding body, the Scientific Committee on Oceans Research (SCOR) established a working group, chaired by Dr ...

  • East Coast gliders yield valuable marine life data

    Eddies can be up to 200 kilometres across and they distribute heat and nutrients around the ocean and form their own distinct habitat. An insight into ocean eddies is also an insight into how ocean dynamics influences regional climate. CSIRO scientists and technicians last month retrieved one of three gliders working in south-east Australia after a five-month program criss-crossing the East ...

  • 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 animals and ...

  • School aboard the Royal Research Ship

    Winners of a nationwide children’s art competition, launched online by the National Oceanography Centre (NOC) today, will give a school class the unique opportunity to explore a Royal Research Ship. Once on board the ship, which is equivalent in volume to 185 double decker buses, the children will tour the main decks and laboratories, be able to dress up as the ship’s crew, and sit in ...

  • 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 different ...

  • First definitive guide to Borneo’s sharks and rays

    Dr Peter Last and Dr William White from the CSIRO Wealth from Oceans Flagship and the Australian National Fish Collection are the book’s lead authors. "Borneo has a rich variety of aquatic habitats ranging from coastal estuaries and coral reefs to the deep ocean," Dr Last says. "This diverse geography is reflected in Sharks and Rays of Borneo, the first comprehensive guide to ...

  • Redefinition of `seawater` to aid climate research

    The science behind understanding the movement of heat through the world’s deep oceans is entering a more exact phase with the adoption of a new thermodynamic definition of what constitutes "seawater". A specialist in thermal fluid dynamics, CSIRO Wealth from Ocean Flagship's Dr Trevor McDougall, recently led an international science team which has – following its acceptance by the ...

  • International collaborative expedition to shed light on microplastics and ocean carbon

    On Friday the 14th of April the RRS Discovery will leave Southampton for a research expedition to the Porcupine Abyssal Plain sustained ocean observatory (PAP-SO) in the Northeast Atlantic. This expedition aims to answer fundamental questions about the distribution, fate and effects of microplastic pollution, as well as measuring sinking particles containing carbon, through an international ...

  • UK OSNAP expedition

    UK Overturning in the N Atlantic Subpolar Gyre Programme (UK OSNAP) is a research project, led by the NOC, which will improve understanding of the circulation and fluxes of the North Atlantic Subpolar Gyre. The transport of heat and freshwater by the North Atlantic Subpolar Gyre greatly affects the climate of the North Atlantic and Europe through its impact on air temperature, precipitation and ...

  • NOC hosts an international meeting to get the most from marine optical technologies

    This group aims to take advantage of the fast development of optical technologies to help progress understanding of the ocean carbon cycle, which determines CO2 levels in the ocean and atmosphere, using large data sets describing particles in the ocean. TOMCAT (Translation of Optical Measurements into particle Content, Aggregation & Transfer) is a Scientific Committee of Ocean Research ...

  • Ocean salinities show an intensified water cycle

    The stronger water cycle means arid regions have become drier and high rainfall regions wetter as atmospheric temperature increases. The study, co-authored by CSIRO scientists Paul Durack and Dr Susan Wijffels, shows the surface ocean beneath rainfall-dominated regions has freshened, whereas ocean regions dominated by evaporation are saltier. The paper also confirms that surface warming of the ...

  • Ecologists use oceanographic data to predict future climate change

    Earth scientists are attempting to predict the future impacts of climate change by reconstructing the past behavior of Arctic climate and ocean circulation. In a November special issue of the journal Ecology, a group of scientists report that if current patterns of change in the Arctic and North Atlantic Oceans continue, alterations of ocean circulation could occur on a global scale, with ...
