Dr Amy Parker and Mr Todd Lyon are working on an Australian Research Council (ARC) project on “geodetic and hydrogeological investigations of groundwater abstraction from confined aquifers: elastic response, heights, and sea level change”. Mr Jack McCubbine is working on a Cooperative Research Centre for Spatial Information (CRCSI) project on the development of AUSGeoid2020, which will replace AUSGeoid09 and be compatible with the pending GDA2020.

Amy joined the Department in November 2015, having completed a BSc (Hons1) in geophysics at the University of Liverpool (UK) and a PhD in InSAR (Interferometric Synthetic Aperture Radar) from the University of Bristol (UK). Her PhD thesis received an international Springer Thesis Award. Her expertise lies in the application of InSAR data to monitor, measure, and understand ground displacements occurring due to natural and man-made phenomena. She is broadly interested in how InSAR can be implemented as a low-cost reservoir monitoring tool, and is currently applying new InSAR datasets to investigate subsidence of the Perth Basin due to groundwater abstraction.

Todd joined the Department in January 2016, having completed a Bachelor of Surveying at Curtin in 2015. He was dux of the graduating class and collected several awards and prizes, including the best project award for establishing a gravity base station on the Curtin campus. His work on the Perth subsidence project has included a gravity survey along the 40-km repeat levelling profile for the application of corrections to spirit levelling. He is currently developing software for the collation and reduction of repeat levelling data and conducting investigations into the application of model-based and deterministic correction strategies for the various sources of systematic error that affect levelling observations.

Jack joined the Department in April 2016, having completed a Masters (Hons1) in mathematics at Exeter University (UK) and is soon to defend his PhD thesis at Victoria University of Wellington (NZ). His Masters dissertation received Exeter University’s Mathematics Research Institute Prize. His PhD project involved the acquisition, reduction and interpretation of airborne gravity data, augmenting it with existing data to model a regional quasigeoid. This will be adopted by Land Information New Zealand to act as a basis for a new official vertical datum for NZ. While in Perth, he is working on AUSGeoid2020, which will include point-by-point error estimates.

The Perth subsidence project is in collaboration with Newcastle University (UK), Landgate and the WA Department of Water. The AUSGeoid2020 project is in collaboration with Geoscience Australia. The Curtin aspects of these projects are led by Professor Will Featherstone.
