Prof. Ross Large is the outgoing President of the Royal Society of Tasmania, a UTAS Distinguished Professor and Professor of Economic Geology.
Professor Large and his team have developed a method for mapping the ocean’s trace elements and have discovered that trace element nutrients have controlled evolution in the oceans through the ages.
- They have investigated over 4000 samples of marine pyrite in black shales covering the last 1000 million years
- Levels of copper and uranium show past CO2 changes, whereas levels of silver and lead track changes in ocean acidification
- Levels of selenium correlate to nearly every major extinction and growth event in Earth’s 4.5 billion year history
All interested people are welcome to attend this free lecture.
