About the research project

During the Last Glacial Maximum (LGM) ice sheets were substantially increased in size compared to present day, resulting in sea levels lower by 120-130m globally. Modelling suggests this reduction in ocean volume resulted in dramatic increases in ocean tide amplitudes (Arbic et al., 2004; Egbert et al., 2004; Griffiths and Peltier, 2008; Griffiths and Peltier, 2009) with consequently increased tidal current speeds. Tidal currents are now known to play an important role in present-day basal melting of Antarctica’s ice shelves (Makinson et al., 2011; Mueller et al., 2012). The interaction between the Antarctic ice sheet and tidal currents during and after LGM has not yet been examined.

The project aims to develop our understanding of what caused the ice sheet retreat since the Last Glacial Maximum. It will test the hypothesis that large tidal currents resulted in enhanced tidal melting of the ice shelves and this varied over time.

Funding

Applicants will be considered for a Research Training Program (RTP) scholarship or Tasmania Graduate Research Scholarship (TGRS) which, if successful, provides:

  • a living allowance stipend of $28,854 per annum (2022 rate, indexed annually) for 3.5 years
  • a relocation allowance of up to $2,000
  • a tuition fees offset covering the cost of tuition fees for up to four years (domestic applicants only)

If successful, international applicants will receive a University of Tasmania Fees Offset for up to four years.

If successful, applicants will also receive a top-up scholarship of $6,000 per annum for 3.5 years. This scholarship is funded from the Australian Government as part of the Antarctic Science Collaboration Initiative program through the Australian Antarctic Program Partnership (AAPP).

As part of the application process you may indicate if you do not wish to be considered for scholarship funding.
