Australia Opens a Wave Data Portal

management of coastal resources by expanding the use of ocean buoys for recording wave data and making it freely-available. Most recently, they have advanced wave forecasting capabilities by deploying a fleet of 10 drifting wave buoys in the Southern Ocean between the Western Australian coast and South Africa. These small, solar-powered wave buoys are expected to float in ocean currents and collect wave data for several years.A network of wave buoys is helping researchers understand the processes and changes driven by waves in Australia’s coastal zone.

Lander Lab: Cost Efficiency of Baited Ocean Landers

crab pot and marked with a surface float. Images are often limited to daylight hours, so lights and batteries are not needed. These simple systems are known as “Baited Remote Underwater Video” (BRUV) platforms.Stereo Baited Remote Underwater Video (BRUV) at Rheeders' Reef, Tsitsikamma, South Africa. Photo by Peter Southwood, Used with PermissionThe use of BRUV systems is favored over extractive sampling methods such as trawling, as many species escape the nets, or are destroyed by capture. Because they are quiet and offer bait, the BRUVs provide a 40% more efficient approach to recording

Underwater Autonomous Glider Departs to Circumnavigate the Globe

critical ocean data from under-sampled, remote regions of the globe.Redwing’s first leg will see it ride the Gulf Stream south of Martha’s Vineyard toward Europe, before sweeping south to stop at Gran Canaria off the coast of North West Africa. Its next leg will take it to Cape town in South Africa, before crossing the Indian Ocean to stop at Perth in Western Australia, then on to Wellington, New Zealand. It will then navigate the Antarctic Circumpolar Current — the most powerful current on Earth — taking it on its longest leg to the Falkland Islands. From here there will be
