Antarctic icebreaker RSV Nuyina will set sail for Mawson analysis station for the primary time this week, 70 years after the ice-strengthened MV Kista Dan sailed an identical route to determine the station.
Whereas Nuyina will ship provides and wintering personnel to Australia’s oldest Antarctic station, in 1954, Kista Dan was on a voyage of discovery, looking for a harbour that had solely ever been considered from the air.
On board was Australian Nationwide Antarctic Analysis Expeditions (ANARE) Chief, Dr Phil Legislation, and his crew, carrying provides and tools to construct the station.
After some hair-raising moments, together with having to free the ship from crushing ice with crowbars, shovels and dynamite, the vessel entered Horseshoe Harbour.
Two days later, on 13 February 1954, Dr Legislation raised the Australian flag and formally named the station in honour of nice Australian explorer and scientist, Sir Douglas Mawson.
No time was wasted, with science packages getting underway nearly instantly.
Australian Antarctic Division Appearing Chief Scientist, Dr Aleks Terauds, mentioned Australia’s lengthy custom of polar science and exploration has prospered ever since.
“Mawson was established in time for the Worldwide Geophysical Yr in 1957-58, which targeted on glaciology, higher atmospheric and cosmic ray physics, meteorology, and gravity and magnetic research,” Dr Terauds mentioned.
“This geophysical analysis continues right this moment, and has included many formidable expeditions to measure the bodily traits of the Antarctic ice sheet, together with to the Prince Charles Mountains, Amery Ice Shelf and Lambert Glacier.
“Mawson can also be an necessary website for organic and ecological analysis, together with the long-term monitoring of penguins and flying seabirds, marine and terrestrial biodiversity analysis, and krill analysis.”
The analysis performed at Mawson informs a spread of our bodies, together with the Fee for the Conservation of Antarctic Marine Dwelling Sources (CCAMLR), the Intergovernmental Panel on Local weather Change, the Settlement on the Conservation of Albatrosses and Petrels, and the Complete Nuclear Take a look at Ban Treaty.
Seabird scientist Dr Louise Emmerson mentioned Mawson was an necessary website for long-term analysis and monitoring of Adélie penguins – a key species within the Antarctic terrestrial and marine ecosystem – with the analysis contributing to ecosystem conservation measures by CCAMLR.
“After 32 years of labor, we proceed to deepen our understanding about how lengthy these seabirds stay for, and what drives the survival of adults, and the fledglings as they navigate the cruel Southern Ocean throughout their first winter,” she mentioned.
“These long-term packages are uncommon, however they allow distinctive ecological insights and are significantly necessary for sea-ice dependent species at a time when polar areas are present process main modifications.
“Whereas we’ve got expanded our analysis to different areas, our Mawson work offers a basis for comparisons, and for validating strategies like our automated digicam community, which screens the penguins year-round.”
Greater than 60 personnel will journey to Mawson on board Nuyina to resupply and refuel the station.
Whereas Voyage Chief Christine MacMillian will journey within the wake of 70 years of historical past, she is worked up to be in her personal uncharted waters, along with her first go to to Mawson and her first time on Nuyina.
“It is going to be an awesome privilege to take such a succesful ship to Mawson as a part of the Australian Antarctic Program, following within the footsteps of Phil Legislation and his crew,” Ms MacMillian mentioned.
“Our expertise can be fairly completely different to those that sailed on the Kista Dan, given the generational modifications in expertise and luxury, however I’m exceptionally excited to go to Mawson after seeing and listening to so many wonderful issues about it.”
Throughout the voyage the ship may also acquire hydrographic knowledge to replace navigation charts printed by the Australian Hydrographic Workplace.
Nuyina’s acoustic devices (its ‘multibeam echosounders’) can be used to gather fashionable survey knowledge for seafloor mapping – a primary for the approaches to Mawson station.
