• 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...
  • The ocean’s glory – and horror

    Photographer Brian Skerry shoots life above and below the waves – as he puts it, both the horror and the magic of the ocean. Sharing amazing, intimate shots of undersea creatures, he shows how powerful images can help make change....
  • Self-driving robots collect water samples to create snapshots of ocean microbes

    For the first time, scientists from the University of Hawai’i at Mānoa (UH Mānoa) and the Monterey Bay Aquarium Research Institute (MBARI) will deploy a small fleet of long-range autonomous underwater vehicles (LRAUVs) that have the ability to collect and archive seawater samples automatically. These new robots will allow...
  • Seaweeds shelter calcifying marine life from acidifying oceans

    Seaweeds create a chemical microenvironment at their surface, providing refuge for calcifying organisms that are at risk from decreasing oceanic pH, shows new research published in the journal Functional Ecology. CO2 in the atmosphere dissolves directly into seawater, lowering the pH and making it increasingly acidic. Kelp and other seaweeds...
  • 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...
  • The Mysterious Lives of Narwhals

    Narwhals are some of the most elusive creatures in the ocean, spending most of their lives in deep water far from shore. But research being presented at the 2018 Ocean Sciences Meeting here on Monday may shed a bit of light on these enigmatic marine mammals. New research shows...
  • 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...
  • Loud ships affect fish communication

    NOAA scientists studying sounds made by Atlantic cod and haddock at spawning sites in the Gulf of Maine have found that vessel traffic noise is reducing the distance over which these animals can communicate with each other. As a result, daily behavior, feeding, mating, and socializing during critical biological...
