Australia Opens a Wave Data Portal
;s average rate of electricity consumption.“Persistent strong winds along the vast Southern Ocean create large waves which bring renewable energy towards the shores virtually continuously,” Wolgamot said. “The south and south-west mainland coastline and the south-west coast of Tasmania in particular experience the highest wave power levels, with exceptionally high-quality waves, with minimal intermittency and relatively small extremes — two characteristics essential for uninterrupted energy production.”A project is underway to use a “Moored MultiMode Multibody&rdquo
Watch: Sleepy Joes Found Together Again in their Hundreds
Scientists have again found aggregations of hundreds of Port Jackson sharks – sometimes known as Sleepy Joes.Scientists from the Institute for Marine and Antarctic Studies of the University of Tasmania found the sharks when they revisited the depths of Beagle Marine Park in Bass Strait using a custom-made Boxfish ROV.Most were females. Males and females often live apart except when mating, but it’s unknown why they are gathering in such numbers.Sleepy Joes usually lay their eggs in the coastal waters of Victoria and mid-to-southern NSW from late winter, so it might be a mating aggregation
Zunibal Acquires Hydroacoustic Company Echoview
Zunibal, a participated company of Nazca Capital, announced their acquisition of Echoview. The Australian company, based in Hobart (Tasmania), is a global leader in hydroacoustic science and software for the processing, analysis, and visualization of hydroacoustic data. This transaction strengthens Zunibal’s technological and innovation capabilities while expanding its range of solutions.Echoview’s technology and its team of scientists and engineers will enable Zunibal to take a qualitative leap forward in the development of technological solutions for sustainable fishing. This includes
FID Made on Australia’s Marinus Link
Shareholders of Marinus Link (MLPL) have made a Final Investment Decision to proceed with Stage 1 of Marinus Link, a proposed undersea and underground electricity and data interconnector that will enable the flow of more low-cost renewable energy between North West Tasmania with Victoria.The project includes high voltage direct current (HVDC) cables, fibre optic cables, a communications station, and converter stations at each end.The project’s cables span 345 kilometers. This includes 255 kilometers of undersea cables across Bass Strait and 90 kilometers of underground cables in Gippsland
Call for Australia to Push for Robust Global Plastics Treaty
from Discovery Bay in under 2.5 hours;● in Western Australia, Tangaroa Blue Foundation coordinated 7.3 tonnes of rubbish being removed from beaches across the state;● in Queensland, 80% of green sea turtles have ingested plastic;● in South Australia, microplastics have been detected inside seafood;● in Tasmania; high levels of microplastics have been found in waters off Bicheno; and● on the remote Torres Strait and Cocos (Keeling) Islands, pristine beaches are being buried under hundreds of tonnes of plastic pollution including from plastic bottles, thongs, lighters and polystyrene fragments.Recycling
CSIRO Science Ship Takes Students on Tasmanian Circumnavigation
Thirty university students and trainers from across Australia will get to circumnavigate Tasmania aboard CSIRO research vessel Investigator.The 10-day voyage is part of a tertiary sea training program called CAPSTAN, the Collaborative Australian Postgraduate Sea-Training Alliance Network, which is being delivered in partnership with CSIRO (Australia's national science agency), marine science industries, universities and government.The program offers a national approach to applied teaching and learning in marine science and wider science, technology, engineering and mathematics (STEM) disciplines.
Xodus Delivers Jobs Guide for Australia’s Marinus Link Interconnector
Global energy consultancy Xodus has delivered a future-looking guide on the jobs that will be required to deliver a major Australian interconnector project to connect North West Tasmania with Victoria, known as the Marinus Link.Marinus Link is a proposed undersea and underground electricity and data interconnector that will enable the flow of more low-cost renewable energy between North West Tasmania with Victoria.Construction on the project, which is currently in the design and approvals phase, is scheduled to get underway in 2026 and is anticipated to create up to 3,300 direct and indirect jobs.
HX Launches Education Program for Antarctic Passengers
HX (formerly known as Hurtigruten Expeditions) has partnered with the University of Tasmania, Australia, and its Institute for Marine and Antarctic Studies (IMAS) on a training program for Antarctic cruise passengers.For the first time, HX’s guests and expedition teams will have the opportunity to explore Antarctic and polar science with world-leading researchers in a university-developed program that blends immersive learning with real-world experiences – with the online course being able to be accessed anywhere in the world.Participants will experience an enriched journey through the
Deep Ocean Heatwaves Associated with Eddies
from global oceans.Marine heatwaves are prolonged temperature events that can cause severe damage to marine habitats, such as impacts to coral reefs and species displacement. These events are becoming more frequent due to global warming, with notable occurrences off Australia’s East Coast and Tasmania, as well as the northeast Pacific coast and North Atlantic. Traditionally, they have been tracked via satellite data focusing on surface temperatures. This new research indicates that deep-water heatwaves may be significantly underreported.The research also highlights the influence of ocean
