Australian Research Vessel Heads South to Study Clouds

of sea level rise.Recently published research has shown the “overturning circulation” of Antarctic waters driving global ocean currents may be slowing down, affecting the redistribution of heat, carbon and nutrients across the globe.  Co-Chief Scientist Dr Annie Foppert from the Australian Antarctic Program Partnership at the University of Tasmania said the meltwater from the Antarctic Ice sheet is reducing the amount of dense water sinking to the deep ocean around Antarctica, slowing ocean currents that control climate.Data collected on the voyage will be compared to earlier measurements

Reseach Finds Fin Whale Songs Shed Light on Migration Patterns

without being intrusive.“The Southern Hemisphere fin whale is a vulnerable sub-species and this method of tracking, whereby microphones are deployed in the deep sea, allows us to observe and map their movements with little disruption,” Professor Erbe said.“Acousticians from the Australian Antarctic Division (AAD) were instrumental in helping us conduct this research, recording almost a million calls at frequencies of 20Hz, which is too low for humans to hear.“This collaboration and expertise allows researchers to listen in to where the whales are going and why, better informing

Clark Named Chair of the Australian Antarctic Science Council

The Australian Antarctic Science Council has a new Chair, with the appointment of Philip Clark AO to lead the organization. The Council was established in 2019 to provide independent advice to Government on the priorities of the Australian Antarctic Science Program.Director of the Australian Antarctic Division, Kim Ellis, said Clark brings a wealth of experience to the role. “I am really excited to have Mr. Clark take on this leadership role in such a pivotal time for Antarctic and Southern Ocean research. Mr. Clark has worked in leadership and governance roles in government, universities

Sea Trials for Australia's New Icebreaker Delayed Due to COVID-19

Australia's newly built Antarctic icebreaking research and supply vessel (RSV) is nearly ready to be delivered, but its sea trials have been delayed due to the coronavirus pandemic, the Australian Antarctic Division (AAD) said.Construction of the ship commenced at Damen’s Galați shipyard in Romania in May 2017, and the vessel was floated out in September 2018 prior to its scheduled arrival at its home port Hobart in 2020. But delays brought on by the COVID-19 outbreak have derailed the delivery schedule.“The fit-out and testing schedule for the vessel is being severely impacted by

Hansen signed the contract on the basis of our references in designing fishing vessels and in-depth know how in marine research vessels and icebreakers for scientific operations, like the RSV NUYINA for the Australian Antarctic Division," said a press release from the Danish company.The concept study will clarify design drivers and evaluate on the preliminary construction, requirements and budget for a new R/V DANA V. The objective for the concept study is to evaluate on the feasibility of the project and provide

is a traditional part of the shipbuilding process. In the case of the ASRV, the choice of one particular coin was symbolic; it was a Dutch silver coin dated 1642, the year that Dutch explorer Abel Tasman become the first European to reach Tasmania. Tasmania is not only where the offices of the Australian Antarctic Division are located, but the island’s capital, Hobart, will be the ASRV’s home port. The ceremony was attended by invited guests and business contacts, including the Romanian Ambassador to Australia Mrs Nineta Barbulescu; Dr. Nick Gales, Director of the Australian Antarctic

IT Package Ordered for Australian Arctic Research Ship

Damen Schelde Naval Shipbuilding (DSNS, Vlissingen) has awarded Radio Holland a contract to supply the IT systems on board the state-of-the-art Antarctic Supply Research Vessel (ASRV) newbuild for the Australian Antarctic Division.   The 160m ASRV is a survey vessel which combines icebreaking, survey and supply activities. The vessel will be able to break ice up to 1.65 meters at a speed of 3 knots and will supply Australia’s permanent research stations in Antarctica and Macquarie Island with cargo, equipment and personnel.   Radio Holland said it will deliver a large IT infrastructu
