Quaternary sea-level changes, coastal evolution and human interactions

Quaternary sea-level changes have profoundly influenced long-term coastal development during the past 2.6 million years and directly impacted on human settlement patterns and the migration of biota in general.  My research has involved examining the evidence for the position of sea level during different time slices of the later Quaternary record relevant to the human colonization of the Australian continent.  Sea level investigations have been based on the analysis of coastal sedimentary successions in outcrop as well as from a range of marine cores.  The latter have been collected from the South Australian Gulfs, the Lacepede Shelf in southern Australia, Gulf of Carpentaria and the continental shelf of New South Wales.  The sedimentary successions have been dated using amino acid racemisation and radiocarbon.

Amino acid racemisation geochronology

Amino acid racemisation, a measure of age, based on the increasing ratio of D- to L-amino acids, has been increasingly used in Quaternary science as a framework for establishing relative and numerical ages of fossils.  With recent developments in reverse phase, high performance liquid chromatography, we are now measuring the degree of racemisation in single foraminifer such as Elphidium sp. The advantage of this analytical protocol is the ability to confidently assess the taphonomic integrity of sedimentary deposits. I am currently using this technique to assess the degree of reworking in coastal sedimentary successions, in midden and associated deposits from the Willandra Lakes region, as well as the Lake Eyre Basin.  With appropriate independent calibration, the degree of racemisation can be used to determine the numerical age of fossils.

Applications of mollusca to Quaternary palaeoenvironmental investigations

Molluscs represent a fascinating class of organisms that provide a wealth of palaeoenvironmental information. My research on fossil mollusca has partly involved determining the ages of sedimentary successions based on amino acid racemisation and radiocarbon dating, as well as classical biostratigraphy.  My interest in mollusca also includes faunal analysis, palaeoecological and taphonomic analyses. These analytical approaches have been applied to natural shell beds from a range of geomorphological and stratigraphical contexts, as well as midden analysis. I have also had a long-standing interest in long-term environmental changes and examining the application of fossil mollusca for quantifying climate change.
