  • Looks swell

    Carnegie Wave Energy created a system to generate electricity from the ocean’s waves to power Australia’s largest naval base. The system, known as CETO 5, has buoys bobbing up and down below the ocean’s surface that drives a pump attached to the seafloor and pushes water through a pipe to the power station. Each buoy can create 240 kilowatts, and all together the system produces about 5 percent of the base’s electricity. The system will need to be upgraded if they plan to put buoys further at sea where the swells are greater.

  • Fish Farm of the Future Goes Vegetarian to Save Seafood

    To avoid depleting the oceans, fish farms should consider feed that is ethically sourced—or even vegetarian. Feeding fish a completely vegetarian diet makes fish farms more sustainable and avoids relying on feeder-fish, which can absorb toxins from their environment. Two X Sea, a California-based company, has developed a vegetarian fish food made from food staples that can be grown on land and sourced from within the US.

  • Scientists are putting seals to work to gather ocean current data

    The Seal Mammal Research Unit at the University of St. Andrews is recruiting and tagging pinnipeds to gather details on ocean conductivity, temperature and depth, collectively called “CTD profiles.” When tagged animals surface, the data they’ve collected are relayed to a global satellite system, decoded by computers, and disseminated to researchers.

  • Coral cultivation offers hope to devastated western Indian Ocean reefs

    Warming water has led to the collapse of coral reef systems in the western Indian Ocean, essential to fisheries, protecting shorelines, and reducing beach erosion and sea-level rise. Marine scientists from Nature Seychelles, as part of an international project to protect and restore the reefs, are promoting varieties of coral that they have found to be resistant to the rise in temperature.

  • Harnessing Local Pride for Global Conservation

    The World Conservation Union estimates that 40 percent of the more than 40,000 species it tracks on its Red List are close to extinction and this problem requires humans to change their behavior to fix it. Rare’s the Pride Campaign uses social marketing to attract attention and communicate the conservation message between local communities and government entities. The Pride Campaign has been replicated around the world for different conservation efforts to protect biodiversity.
