• A ‘regime shift’ is happening in the Arctic Ocean

    Scientists at Stanford University have discovered a surprising shift in the Arctic Ocean. Exploding blooms of phytoplankton, the tiny algae at the base of a food web topped by whales and polar bears, have drastically altered the Arctic’s ability to transform atmospheric carbon into living matter. Over the past...
  • Like humans, beluga whales form friendship social networks

    A groundbreaking study using molecular genetic techniques and field studies brings together decades of research into the complex relationships among beluga whales (Delphinapterus leucas) that spans 10 locations across the Arctic from Alaska to Canada and Russia to Norway. The behavior of these highly gregarious whales, which include sophisticated...
  • How marine snow cools the planet

    University of Sydney scientists have modelled how carbonate accumulation from ‘marine snow’ in oceans has absorbed carbon dioxide over millennia and been a key driver in keeping the planet cool for millions of years. The study, published in Geology, also helps our understanding of the ocean’s future capacity to...
  • Andrew Forrest commits $100m to ocean research

    Founder of the Fortescue Metals Group, Andrew Forrest, has announced he will contribute $100 million to his Minderoo Foundation to extend its activities to the protection of the ocean. Mr Forrest said the funding would support the Minderoo Ocean Research Initiative, a new global research program to be undertaken...
  • Study shows rapid decline of fishery stocks across Australia

    The number of large fish species in Australian waters has declined by 30% in the past decade, mostly due to excessive fishing, according to new research. Marine ecology experts are calling for changes to fisheries management after publication of the study by scientists from the University of Tasmania and...
  • Global sea levels rise at rates beyond initial predictions

    According to a study assessing 25 year’s worth of satellite data, global sea levels are rising at an accelerated rate, which could result in a rise twice as high as previous projections by 2100. With results published in the journal Proceedings of the National Academy of Sciences (PNAS), researchers...
  • The Rariophotic

    New ocean zone is home to many new species of reef fish Based on the unique fish fauna observed from a manned submersible on a southern Caribbean reef system in Curaçao, Smithsonian explorers defined a new ocean-life zone, the rariphotic, between 130 and 309 meters (about 400 to 1,000...
  • Recordings spout secrets behind blue whale behaviour

    Researchers are using underwater microphones to interpret and characterize the calls of blue whales swimming through Southern California’s oceans, revealing new insights into the behavior of these endangered marine mammals, according to new research. Stretching nearly 30 meters (100 feet) long and weighing up to 172 metric tons (190...
  • Primitive fish had more sense than we thought 

    CT scans of vertebrate fish fossils have found early signs of sophisticated electroreception systems, which paved the way for the amazing detection ability of sharks, lungfish and other living species. The research, led by Flinders University palaeontologists Ben King and Professor John Long, found evidence of electroreception in the...
