  • Fertilize the ocean, cool the planet?

    Original story at MIT News Like the leaves of New England maples, phytoplankton, the microalgae at the base of most oceanic food webs, photosynthesize when exposed to sunlight. In the process, they absorb carbon dioxide from the atmosphere, converting it to carbohydrates and oxygen. Many phytoplankton species also release dimethyl ...

  • 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, ...

  • 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 ...

  • Global ocean data for global monitoring

    Local weather conditions have always been linked to global climatic developments. Global climatic factors – such as El Nino or La Nina in the Pacific Ocean - have an impact not only on neighbouring continents; their influence is also felt in regions as far removed as continental Europe. With the onset of global climate change, its influence on local weather is getting more distinct. Severe ...

  • Rivers and oceans as clean sources of energy

    The third day of the acqua alta, which will take place from 10 to 12 November at the CCH - Congress Center Hamburg - will be focusing on the topic of hydro energy. Experts from Germany and abroad will be presenting new developments and projects. Not only will the classic types of energy generation from water power be addressed, but also the advanced and climate-friendly use of tides and sea ...

  • Iron’s mixed blessing for health of oceans

    Technology’s answer to climate change in a world in which humans go on releasing carbon dioxide in the atmosphere has just had another setback. The idea of fertilising the planet’s oceans with iron filings to stimulate green growth and turn the oceans into a carbon sink isn’t so simple as hoped. Two studies – both involving experiments at sea – have ...

  • Computational Ocean Sciences – Assistant Professor

    The Department of Ocean, Earth, and Atmospheric Sciences at Old Dominion University invites applications for a tenure-track faculty position beginning fall 2017. We seek candidates with research interests in marine ecosystems, oceanographic biogeochemical processes, and climate change. The successful candidate will have a computational focus, preferably taking advantage of the increasing ...

  • Tasmanian scientists expand their view of the ocean

    The technology is being provided through the new Tasmanian science node of the Australian Integrated Marine Observing System (IMOS) which is being launched today at CSIRO in Hobart. “The ocean waters and habitats surrounding Tasmania are important to the state’s economic wellbeing, yet are poorly understood,” IMOS Director, Tim Moltmann, said. “This complex environment has ...

  • Solving the Problem of Plastic Waste in Oceans

    Ocean Conservancy today announced the global launch of Stemming the Tide: Land-based strategies for a plastic-free ocean – a first-of-its-kind, solutions-oriented report. Produced in partnership with the McKinsey Center for Business and Environment, the report outlines specific land-based solutions for plastic waste in the ocean, starting with the elimination of plastic waste ...

  • 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 ...


  • Arctic Ocean will be ice-free in 30 years

    New research says the Arctic might lose most of its ice cover in summer in as few as 30 years instead of the end of the century as was previously predicted. The amount of the Arctic Ocean covered by ice at the end of summer by then could be only about 1 million square kilometres, or about 620,000 square miles, down from today’s 4.6 million square kilometres, or 2.8 million square miles. While ...

  • 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 ...

  • Mechanical fin power: oceanic power generation

    Tim Finnigan, a professor of ocean engineering at the University of Sydney in Australia designed a radical oceanic energy collector inspired by the design of shark tails. Mimicking the successful evolutionary design of the fish species, he constructed a device that seizes the power of the sea. “I realized the systems that function the best are the ones that already exist there,” said Finnigan. ...

  • Australia’s ocean research ship open to Sydneysiders

    RV Southern Surveyor is the only dedicated Australian research ship equipped to perform marine research in the offshore waters of Australia and Oceania. It is used by Australian universities, CSIRO and other research organisations and their international collaborators to improve our understanding of the marine environment. Australia’s ocean territory is the third largest in the world and only ...

  • 270,000 tons of plastic waste floating in oceans

    A new study estimates nearly 270,000 tons of plastic is floating in the world's oceans. That's enough to fill more than 38,500 garbage trucks. The plastic is broken up into more than 5 trillion pieces, said the study published Wednesday in the scientific journal PLOS ONE. The paper is the latest in a nascent field where scientists are ...

  • A human-focused approach to measuring ocean health

    A new index for measuring the health of oceans considers the benefits of the sea to humans, as well as the status of natural components, such as biodiversity. According to the researchers who developed the index, it provides a powerful tool for allocating resources and improving policy in the management of marine ecosystems. From an ecosystem services perspective, the oceans provide ...

  • Predicting the future of oceans - UBC and Nippon Foundation partnership

    University of British Columbia researchers have launched a $13-million, nine-year research program with Japan's Nippon Foundation (NF) to study the future of the world's oceans and to monitor the impact of human activities on seafood resources. With support from the Foundation's Marine Affairs Department, the NF-UBC Nereus - Predicting the Future Ocean program at the UBC Fisheries Centre will ...

  • Time to stop losing ocean data to vandalism

    More must be done to prevent damage of ocean data buoys that costs money, vital data — and lives, say Sidney Thurston and M. Ravichandran. The global community relies on a rapidly expanding ocean observing network to understand the climate and ecosystems, to help warn against ocean-borne hazards such as tsunamis and storm surges caused by cyclones, and to support sea rescue ...

  • 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 ...

  • Record Greenhouse Gas Levels Impact Atmosphere and Oceans

    The amount of greenhouse gases in the atmosphere reached a new record high in 2013, propelled by a surge in levels of carbon dioxide. This is according to the World Meteorological Organization’s annual Greenhouse Gas Bulletin, which injected even greater urgency into the need for concerted international action ...
