AESC wrap up

Written by Kathryn Amos on . Posted in Meetings

What a great conference! AESC certainly delivered some top notch research presentations this week. My highlights from the last few days of the conference have been at very different ends of the geologic timescale - Southern Hemisphere Quaternary, and Neoproterozoic Earth. The resolution of investigation and interpretations are strikingly different when listening to presentations on these different ages of succesion.

We heard from several high-resolution palaeoclimatic interpretations from lake, marsh and ocean cores, helping to shed light on key research questions such as what reconstructions of hydrological variability from around Australia can tell us about continental scale and global atmospheric climate during the Quaternary, the reconstruction of the position and strength of ocean currents, and whether hydrological variability and increases in dust accumulation could be related to megafaunal extinction. Dust also featured in the final plenary presentation by Prof. Paul Hoffman about Snowball Earth, which also highlighted the role of cap carbonate sedimentology, stratigraphy and geochemistry in our reconstructions of this time. The usefulness of detrital zircon chronologies for piecing together the palaeographic reconstructions of ancient basins was seen in several presentations.

The next AESC won't be for another two years, but there are tentative plans in the pipeline for a GSA Sedimentology Group field workshop during 2017. Watch this space!AESC
