The Miocene is the Future »

2pm 11 October 2018

To better understand and predict future climate change we often to look to past periods of global warmth as analogues and testbeds for models.  The Miocene (23 to 5 million years ago) is probably the best analogue for the range of carbon dioxide concentrations, warming, sea level rise, and  ice volume losses that...

An extended record of Indian Ocean Dipole variability from Indonesian Corals »

4pm 9 October 2018

The Indian Ocean Dipole (IOD) is an ocean-atmosphere climate oscillation within the Indian Ocean basin and one of Australasia’s key climate drivers that influences the distribution of rainfall across the region. Future projections of IOD activity suggests that extreme positive IOD events may become more frequent...

Volcanoes, Iron, and Phytoplankton in the Southern Ocean »

2pm 4 October 2018

Phytoplankton in the ocean supply half of the oxygen in Earth’s atmosphere. Iron supply limits the growth of phytoplankton in the Southern Ocean as well as elsewhere in the global ocean. Situated entirely within the anemic Southern Ocean, Australia’s only active volcanoes, Heard and McDonald islands on the...

Isotopic Anomalies in the Mediterranean Sea record »

1pm 3 October 2018

In this seminar I will give an overview of my PhD research, specifically the isotopic anomolies from an eastern Mediterranean sediment core and the implications for the reconstruction of past sea levels.

You can’t handle the tooth: three stories on improving our understanding of the isotopic variation in archaeological samples »

5pm 2 October 2018

Isotopic analysis of human remains has become a key scientific technique employed to gather direct evidence of the diet and mobility of past populations. Geographical variation in the isotopic values for two elements, oxygen and strontium, provide a basis for measuring human mobility between regions with differing...

Bottom topography and oceanic variability - Joe LaCasce (U. Oslo) »

3pm 2 October 2018

Many fundamental theories of ocean circulation neglect bottom topography. Indeed, flat bottom ocean basins are still used today to study a range of phenomena. Here we examine evidence that the bottom affects eddies throughout the water  column. Current meter data point to the existence...

Multi-faceted mineral exploration: something for everyone »

2pm 27 September 2018

Mineral exploration is known as a boom and bust industry. In boom times, explorers make money, drill, get excited and some even direct funds towards research to break into new frontiers such as exploration technologies for application in buried, prospective terranes. In bust times, explorers tighten their belts in...

Using Antarctic ice to unravel past changes in the Earth's magnetic field »

1pm 26 September 2018

Geomagnetic excursions provide information on field mechanics and serve as a chronostratigraphic tool. Interpretation of sedimentological paleointensity records is complicated, and volcanic rocks provide only non-continuous records. Another means for reconstructing paleomagnetic intensity is analyzing cosmogenic...
