  • 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 ...

  • 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 ...

  • US scientists head to Antarctica for climate research

    More than 30 scientists will embark on a research cruise this month to the Southern Ocean, which surrounds Antarctica. There they will combat cold and wind to study how gases that impact climate change move between the atmosphere and the ocean under high winds and seas. The Southern Ocean Gas Exchange Experiment, a six week cruise aboard the research vessel Ronald H. Brown, is co-sponsored by ...

  • Ocean temperatures and sea level increases 50% higher than previously estimated

    New research suggests that ocean temperature and associated sea level increases between 1961 and 2003 were 50 percent larger than estimated in the 2007 Intergovernmental Panel on Climate Change report. The results are reported in the June 19 edition of the journal Nature. An international team of researchers, including Lawrence Livermore National Laboratory climate scientist Peter Gleckler, ...

  • University of New Hampshire Research Project

  • 25 years of research in polar seas aboard the research vessel Polarstern

    On December 9, 2007, the ice-breaking research vessel Polarstern will celebrate her 25th anniversary of service: since 1982, the world¹s most powerful polar research vessel has been venturing to the Arctic and Antarctic on behalf of the Alfred Wegener Institute for Polar and Marine Research, part of the Helmholtz Association. 7600 scientist from 36 nations have gained insights into the polar ...

  • 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 ...

  • Antarctic Ocean Losing Ability to Absorb Carbon Dioxide

    Norwich, UK - Recent climate change brought on by human activities has weakened one the Earth's natural defenses against global warming. Atmospheric carbon dioxide is not being absorbed by the Southern Ocean as quickly as it once was, an international research team has found. Scientists have observed the first evidence that the Southern Ocean’s ability to absorb the major greenhouse gas carbon ...

  • New EU research to investigate ocean acidification impact on ecosystems

    Emissions of carbon dioxide (CO2) through human activities have a well known impact on the Earth's climate. What is not so well known is that the absorption of this CO2 by the oceans is causing inexorable acidification of sea water. But what impact is this phenomenon having on marine organisms and ecosystems? This is a question to which researchers have few answers as yet. That is why the ...

  • India’s First Sediment Trap-Based Flux Studies in Southern Ocean

    In order to understand the response of the Southern Ocean as a carbon sink and its response to changing global climate conditions, a long-term flux study called “Southern Ocean Carbon Processes-SOCarP” was conceived at the National Centre For Antarctic and Ocean Research (NCAOR), India, using moored sediment traps. In early 2017, ...

  • New era dawns for world’s oceans via EPOCA

    Last June, the EU’s largest research consortium to combat ocean acidification was launched. The European Project on Ocean Acidification (EPOCA) combines over 100 scientists from 27 organisations in 9 countries. Its aim is to document ocean acidification and investigate its impact on biological processes. Based on this information the project can then predict its consequences for the next 100 ...

  • Ocean-Climate Links Central to $97.7 Million Research Contract

    WASHINGTON, DC, August 23, 2007 (ENS) - 'No longer will ocean exploration and research be limited to scientists. Everyone with a connection to the web, including students, teachers, decisionmakers and the general public, will be able to have access to these undersea networks, enthused Mark Abbott today. As dean of Oregon State University's College of Oceanic and Atmospheric ...

  • Largest Antarctic ice sheet more sensitive to ocean warming than previously thought

    The largest ice sheet in the world, the east Antarctic ice sheet, may succumb to climate change faster than thought, according to recent research. Warming ocean currents, triggered by shifting wind patterns, could accelerate melting of the ice sheet, leading to a rise in sea levels, say the researchers. The east Antarctic ice sheet has an average thickness of over 2 km and can reach more than 4 ...

  • 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 ...

  • 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 ...

  • New Discoveries Improve Climate Models

    New discoveries on how underwater ridges impact the ocean's circulation system will help improve climate projections. An underwater ridge can trap the flow of cold, dense water at the bottom of the ocean. Without the ridge, deepwater can flow freely and speed up the ocean circulation pattern, which generally increases the flow of warm surface water. Warm water on the ocean's ...
