Lecture: “Ocean acidification and atmosphere oxygenation in deep time”, Tuesday, 2 February 2016, TMAG, Hobart

Date & time: Tuesday, 2 February 2016, 8.00 pm

Venue: Royal Society Room, Customs House Building, TMAG, Hobart

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.
