Life beneath the sheets: 9000 years in the dark

27 July 2009

Researchers at Geoscience Australia have unravelled the development of a unique seafloor community thriving in complete darkness below the giant ice sheets of Antarctica. The community beneath the Amery Ice Shelf in Antarctica is 100 km from open water and hidden from view by ice half a kilometre thick. This ecosystem has developed very slowly [...]

Ancient eruptions warn of climate change and mass extinctions

4 June 2009

A Curtin University researcher has shown that some ancient periods of massive eruptions released green house gases so quickly that they caused rapid climate change and mass extinctions. But today we are adding carbon dioxide to the atmosphere faster than even the most rapid sequence of eruptions. “We have carefully dated minerals contained in the [...]

It’s life, but not as we know it

22 August 2005

Billion year old bacteria in NT rocks and bugs from outer space Researchers from the CSIRO, Sydney University and Colorado State University have developed a means of detecting signs of ancient microbes which may have lived on Earth or come from outer space. The group already has picked up signs of bacteria more than a [...]

Did the earth move for you?

16 August 2005

Recent Australian earthquakes In the past 100,000 years, Australia has been hit by at least five large, landscape-changing earthquakes, a young Melbourne researcher has found. Each was at least 10 times as big as the 1989 Newcastle earthquake, which caused $1.5 billion damage. And he expects there to be more. Mark Quigley, from the University [...]

Filling the hole on mine safety

30 August 2004

A PhD student in QLD improves mine safety with her predictive computer program Some of the risk involved in working underground is being reduced by a revolutionary approach to predicting the collapse of mine retaining walls . “In mining, huge voids are created underground when valuable ore is removed. Voids often the size of a [...]

New theory on Mediterranean Mountain Ranges

19 August 2003

A new theory to explain the formation of the mountains of Western Europe will be unveiled in Melbourne today (Wednesday). Until now, geoscientists worked on the basis that mountain ranges such as the Alps were formed when the tectonic plates carrying Europe and Africa came into collision.

Continental drift shapes the earth and drives evolution and extinction

22 August 2002

Forget meteorites. Bin volcanic eruptions. When it comes to mass extinction continental drift is the mega-killer, claims Australian palaeontologist Dr Malte Ebach.

Fossil molecules help to detect ET

23 August 2001

Fossil molecules from cells of bacteria and algae many millions of years old may hold the key to reading life signals from extra terrestrial sources, according to research conducted by AGSO – Geoscience Australia researcher, Dr Graham Logan. Some molecules within living cells fossilise very well and can reveal evidence of past life, environments and [...]

Fossil molecules, oil, dinosaurs and the weather

15 May 2000

Fossil molecules in rocks obtained from mining operations have unlocked dramatic secrets of immense fluctuations in climate and sea level in prehistoric times. The method charts climate changes through history and paints a new picture of the Earth’s vegetation cover.  It is used by the petroleum industry to identify likely drilling sites for oil wells.

The big rip: Antarctica split in two

7 May 2000

A new geological study in the Antarctic has shown that the coldest continent split in two about 30 million years ago, and solved a long-standing mystery among geoscientists. Geoscientists try to understand the evolution of the land masses which form countries and continents in today’s world, by reconstructing the movements of tectonic plates.

Undersea volcanos unlock secrets of rich ore deposits

1 May 2000

Researchers in Monash University’s Australian Crustal Research Centre have made a discovery that could have important implications for pinpointing where to look for large deposits of metal. While the Earth’s crust had previously been thought to be the source of most metals, these new findings suggest that they in fact originate much deeper, in the [...]
