31st Oct Speaker event: Understanding Climate Change: All the Natural and Human Causes with Emeritus Professor Ray Cas

Ray Cas is recognised as one of the principle figures in volcanology in Australia and highly respected as a world-class researcher and innovator in this field for over 50 years. He has

an honorary position at the University of Tasmania and in late October CODES/ES will be celebrating his contributions to the organisation and the updated edition of his classic book launched earlier this year. The original book published in1989, is a touch stone for anyone looking at volcanic successions. The new edition encapsulated the old with an additional 30 years of new research and knowledge in Physical Volcanology. GSA is excited that as part of Rays’ visit he has agreed to give us a presentation on climate change including the interaction between volcanos and climate.

Don’t miss this excellent opportunity hear the latest insights into this topic from one of Australia’s preeminent volcanologists.

31st Oct: Nibbles from 5:30

Talk starts at 6 pm in the Earth Sciences Lecture Theatre

Saturday 5th of October: Spring field trip: ‘Glacial features of the Lake Rowallan and upper Forth Valley’ led by Nick Roberts

Join us on the 5th of October for a one day field trip in the Lake Rowallen-upper Forth Valley with field leader Nick Roberts examining some of northern Tasmanian’s Quaternary glacial features. The sites are mainly on forestry and hydro tracks with one site requiring a few hundred metres of walking on a forestry track. Sites we will visit include examples of end mo-raines as well as glaciolacustrine deposits and a roche moutonnee. Don’t know what I am talking about? Maybe you should join us to find out!

The Royal Society of Tasmania and The Geological Society of Australia present: Tasmania’s Geologically Recent Glacial Records with Nick Roberts

When: 1.30 pm Sunday 6 October 2024

Where: Meeting Room, QVMAG at Inveresk

Admission: Free for members of the Royal Society of Tasmania and the Geological Society of Australia

$6 general admission

$4 for students, QVMAG or TMAG Friends, and members of the Launceston Historical Society

Tasmanian landforms and sediments provide the only direct records of repeated glaciation from a tectonically stable landmass in the southern mid-latitudes. They afford key opportunities to understand Earth’s most recent ice ages, including interhemispheric disparities and Antarctica’s influences on Australia. New sites and evolving techniques are expanding our insights on Tasmania’s last few million years of cryosphere fluctuations.

Nick is a geologist and geomorphologist specialising in landslides and glacial records. His expertise in interpreting mountainous landscapes stems from work across western North America, South America, Europe, Central Asia, and the Middle East. Since joining Mineral Resources Tasmania’s Geological Survey Branch in 2019, Nick has been helping to better understand Tasmania’s landscape evolution and consequent natural hazards.
