Down Under
hydrographic survey can improve accuracy and dramatically reduce fuel consumption, and Baker is seeing much wider acceptance and adoption of autonomous systems in Australia’s maritime domain. In May, a USV developed by EGS Australia successfully completed its first major deployment offshore Western Australia, powered by Greenroom Robotics’ GAMA autonomy system. Deployed 100 kilometers east of Esperance for a 42-day mission, the USV Fremantle 01 was tasked with conducting extended hydrographic survey operations in remote offshore waters. The vessel operated through rough conditions, including
Underwater Autonomous Glider Departs to Circumnavigate 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 possible stops in Brazil and the Caribbean before heading back to Cape
Unique Group’s USV Wins UK Ports Innovation Award 2025
and Awards Ceremony on September 3, 2025.The UK Ports Committee nominated Unique Group for the award in recognition of its advancements in subsea robotics and hydrographic surveying. The committee was impressed by the company’s deployment of the Uni-Mini Unmanned Surface Vessel (USV) in Western Australia, the first commercial project globally to utilize the Norbit iWBMS multibeam sonar for shallow-water survey applications, demonstrating capability in complex marine environments.The Uni-Mini has also proven its capabilities closer to home in the UK. Earlier this year, Unique Group successfully
Western Australia Can’t Wait [for a Decommissioning Hub]
changes.Australia doesn’t have the recycling facilities needed for the job, although the government has been taking some action on the issue. It published a decommissioning roadmap in 2024 and has set up an Offshore Decommissioning Directorate.The Australian Marine Complex in Henderson, Western Australia (WA), has previously been flagged as the most promising site for a decommissioning hub, but, says local environmental organizations and unions, along came AUKUS.“In late 2024, the federal government announced that Henderson would be developed as a base for servicing nuclear-powered submarines
Wine Down Under
Brad Adams, co-founder of Subsea Estate in Western Australia, has just retrieved vats of his latest wine from the seabed just off the coast of Augusta.Partnered with wife and co-founder Jodee Adams and chief wine maker Emmanuel Poirmeur, he is creating a product unique in the southern hemisphere.For the last two years, Subsea Estate has produced Semillon and Shiraz that has undergone its secondary fermentation 15 meters deep in the Southern Ocean.The idea was originally inspired by the 1998 discovery of thousands of bottles of 1907 Heidsieck & Co Monopole Goût Americain Champagne on the
Call for Australia to Push for Robust Global Plastics Treaty

Nortek Nucleus Supports Coral Reef Photogrammetry Project
In a collaboration between the Norwegian University of Science and Technology (NTNU), University of Sydney, California Academy of Sciences (CalAcademy), Oceanly, University of Western Australia, and University of Auckland, supported by Inkfish, the University of Sydney’s Seeker AUV, equipped with a Nortek Nucleus 1000, worked alongside divers to create a 3D map of a coral reef off the coast of Tonga.Researchers from NTNU, the University of Sydney, and CalAcademy are working together to investigate how mesophotic reefs (low-light coral reefs in middle-depth waters) support the genetic diversity
Anthropocene Markers
is anthropogenic - it doesn't exist on its own in nature.Plutonium isotopes can remain in ocean sediments for thousands of years due to their long half-lives, and this week, researchers from Edith Cowan University (ECU) confirmed plutonium levels in sediment at the Montebello Islands off Western Australia of up to 4,500 times greater than the Western Australian coastline.Three plutonium-based nuclear weapons tests were conducted by the UK at the Montebello Islands in the 1950's. The first, code named Operation Hurricane, had a weapon's yield of some 25kT, and formed a crater in the seabed
Strategic Move Brings Decom Engineering's Base to Aberdeen
