About the research project

The Earth continues to deform following past changes in glacial loading and unloading, notably since the Last Glacial Maximum. The Denman Glacier region shows surprisingly low rates of present-day uplift and this is yet to be explained by models of glacial isostatic adjustment (GIA), the ongoing response of the solid Earth to ice-ocean loading changes. This gap in knowledge affects estimates of present-day ice mass change (and hence sea-level change) as GIA is an essential correction to satellite datasets of ice-sheet change.

This project will focus on modelling the deformation of the Denman Glacier region based on new ice history and relative sea-level data, new GPS bedrock velocities, and numerical models of glacial isostatic adjustment and sea-level processes.

The project will focus on creating three-dimensional reconstructions of ice history, with a focus on the late Holocene and using these as inputs into models of GIA, and then comparing these models to RSL and GPS observations from the region. The outputs of the project are an improved model of GIA for this region, validated by independent data, and new estimates of present-day ice-mass change by applying the new model to satellite datasets.

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)

This project is part of the ARC Australian Centre for Excellence in Antarctic Science (ACEAS). Candidates will be considered and assessed for ACEAS top-up scholarship eligibility (valued at $5,000 per annum for 3.5 years) upon ranking of the applicants by our GRCs and alignment of the project with ACEAS.

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

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

Selection Criteria

The project is competitively assessed and awarded.  Selection is based on academic merit and suitability to the project as determined by the College.

Additional desirable selection criteria specific to this project:

  • Experience modelling solid Earth deformation and/or knowledge of ice sheet models

Application process

There is a three-step application process:

  1. Select your project, and check you meet the eligibility and selection criteria;
  2. Contact the Primary Supervisor, Prof Matt King to discuss your suitability and the project's requirements; and
  3. Submit an application by the closing date listed above.
    • Copy and paste the title of the project from this advertisement into your application. If you don’t correctly do this your application may be rejected.
    • As part of your application, you will be required to submit a covering letter, a CV including 2 x referees and your project research proposal.

Following the application closing date applications will be assessed within the College. Applicants should expect to receive notification of the outcome by email by the advertised outcome date.
