Smoke from devastating bushfires in Australia's Grampians national park has been detected thousands of kilometers away at a Chilean research station in Antarctica, highlighting the far-reaching impact of the fires.
Bushfires in the Grampians national park in Victoria have burned through more than 76,000 hectares of land and destroyed at least three homes. Scientists detected the smoke particles at the Profesor Julio Escudero Base, a Chilean research station on King George Island, at the northern tip of the Antarctic peninsula. The smoke signal was first discovered on 21 December and was present the following week, including a detection on Sunday, the latest day for which data was available.
The particles were at a height of at least 5km up in the atmosphere. The fires continue to burn, although firefighters say conditions have eased. ADr Raúl Cordero of the University of Groningen, whose team runs Escudero Base, said that once it falls to ground, black carbon from bushfire smoke may increase snowmelt on Antarctica. Instruments at the Profesor Julio Escudero Base, used to measure smoke particles in the air, detected the smoke. ‘It’s going to eventually make the snow darker, and by doing so, it’s going to contribute to accelerating the melting of the snow. ‘ Cordero has previously found that, based on samples taken between 2016 and 2020, black carbon pollution from Antarctic tourism and research activities was probably ‘The particles produced by fires have exactly the same effect on the snow as particles produced by the combustion of diesel … for powering ships,’ Cordero said. Nasa’s aeronet robotic network ‘The instruments allow us to detect not only the presence of particles but also the type of particles,’ Cordero said. ‘We are reasonably sure the source of this smoke is the active fire system covering Australia.
