Vale Jean Rϋeger

18 Aug '25

Colleagues, It is my melancholy duty to inform all on this list that Associate Professor Jean Rϋeger passed away on Saturday afternoon at the Prince of Wales hospital. Two months ago, he contracted an incurable metastatic lung cancer and declined very rapidly. He has made an enormous contribution to surveying education, EDM calibration and high precision surveying both internationally and across Australia. Details of funeral arrangements are yet to be finalised. I will inform this email list when they are forthcoming. Kind regards, Craig Dr Craig Roberts Head of Surveying Program Associate Professor School of Civil and Environmental Engineering Room CE412, Level 4, H20 UNSW SYDNEY 2052 E: c.roberts(a)unsw.edu.au<mailto:c.roberts@unsw.edu.au> W: https://url.au.m.mimecastprotect.com/s/5wEjCyoNROTN50AqLCZfQsxiqd0?domain=u… T: 02 9385 4464 (MS Teams) [A picture containing logo Description automatically generated] CRICOS Provider Code 00098G UNSW is located on the unceded territory of the Bedegal (Kensington campus), Gadigal (City and Paddington Campuses) and Ngunnawal peoples (UNSW Canberra) who are the Traditional Owners of the lands where each campus of UNSW is situated.

CSIRO industry PhD on machine learning analysis of precise GNSS time series with application to sea-level rise
by Matt King 14 Aug '25

14 Aug '25

Dear Colleagues I am readvertising the below position - please distribute this to present or former honours/masters students interested in undertaking a PhD in data science/geodesy. The project is well supported with a $12k/yr topup and substantial project support, and an internship with Geoscience Australia. Together with CSIRO and Geoscience Australia I am pleased to advertise a new and well supported Industry PhD project. The project seeks to improve the accuracy of estimates of Australia's 3D motion and deformation. The improved vertical land motion estimates from this PhD will then be applied to improve our understanding of sea level rise around our coastlines. This collaboration between CSIRO Data61, UTAS and Geoscience Australia will develop novel unsupervised machine learning approaches to detect hidden and subtle changes in highly precise measurements of Earth's changing shape. Hundreds of continuous GNSS sites now operate across Australia, and tens of thousands globally, allowing Earth's 3D motion to be theoretically tracked at the millimetre level. However, the utility of these data is degraded by undiagnosed and hidden changes in the time series due to hardware, geophysical or environmental changes. Robust and repeatable automated techniques are currently less accurate than laborious manual expert human analysis. Novel methods that detect hidden, subtle changes in high-precision continuous GNSS time series will be developed and then applied to publicly available data from Australian GNSS sites. This work will improve satellite positioning products used by Australian industry, government and researchers. For instance, quality-controlled data products will improve our understanding of Australia's vertical land motion, and this will directly improve estimates of sea-level rise. Other applications include improving knowledge of the present-day strain of the Australian crust, yielding insights into seismic risk. The developed methods will be operationalised at Geoscience Australia. This exciting and well-supported project allows a candidate to work on a pressing societal problem and work closely with partners in CSIRO Datat61 and Geoscience Australia. The project will include an internship with Geoscience Australia. There is a global shortage of experts in this area, including within Australia. The expertise provided in this PhD will place the candidate as one of Australia's experts in geodetic data analysis, of which Geoscience Australia is the national lead. The student will work with a great team including me (Primary Supervisor), Daniel Smith (CSIRO Data61), Anna Riddell (GA), and Christopher Watson (UTAS). Please get in touch with me if you have any questions. Please note applications will only be considered from Australian citizens or Permanent Residents, or a New Zealand citizens.
