Kimberley air to inform climate modelling 4/8/2013

Science Network WA


THE CSIRO has been monitoring air quality at Lake Argyle in the Kimberley, and in Darwin and Jabiru in the Northern Territory, for 10 years.

CSIRO’s Dr Ross Mitchell says the research began because it became clear that aerosol has an important but poorly understood effect on climate.

“What we’ve done is to provide the climate modellers with a very firm basis on which to build and test their models of how the fire regime and the subsequent emission of smoke aerosol can be realistically represented in the global climate models,” he says.

“The smoke that we are talking about comes from the seasonal burning of the tropical savannah.

“That includes the Kimberley region of Western Australia, the top two thirds of the Northern Territory, and adjacent areas of Queensland.”

Dr Mitchell says most of the fires are deliberately lit for land management, with the majority of the smoke generated during the late dry season between August and November.

Pest millipede gets a leg up 23/9/2013

A scientist says a recent low-speed train collision in Perth attributed to Portuguese millipedes on the tracks is a symptom of growing millipede numbers in WA.

From The West AustralianDr Geoff Baker says we can expect to see more millipedes in Perth and the South West, similar to the 1970s South Australian experience.

“It was invading houses in huge numbers and creating a hell of a nuisance problem to people,” he says.

Multiple dating techniques used to eliminate rock art disputes 8/8/2013

A team of scientists is travelling to the eastern Kimberley to sort out the vexed question of rock art dates.

The hot question is when prehistoric artists stopped painting in the Gwion Gwion style, and when they started painting Wanjinas.

Science Network WA first published my interview with archaeologist Fiona Hook on 8 August 2013, it has since appeared in the Broome Advertiser and Kimberley Echo newspapers on 29 August and on The West Australian’s regional website on 2 September of the same year.

The latter has the best headline, albeit with dubious grammar.
