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

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

New Alliance Set Up to Boost Australia’s Subsea Sector
of subsea assets requiring to be decommissioned includes over 1,500 wells and structures and 4,500km of pipelines with major opportunities for specialist plugging, cutting, inspection and recovery technologies,“Meanwhile in offshore wind, largely focused on key areas in the South East and Western Australia, there are projects totaling 11GW. The subsea requirement for cables, foundations, survey and protection systems across upwards of 700 turbines provides a significant future opportunity for UK subsea companies,” Gordon concluded
