I am Professor of Polar Geodesy and ARC Future Fellow at the University of Tasmania. My field of expertise is geodetic observation of Earth deformation and the global water cycle, including ice-sheet mass balance and sea-level change and particularly using the Global Positioning System (GPS) and the Gravity Recovery and Climate Experiment (GRACE). I also work on reduction of systematic and random errors in these techniques in order to maximise the information content in the data and improve the reliability of the interpretations. I have authored more than 80 peer-reviewed publications including several articles in the leading scientific journals Science, Nature, Nature Geoscience, Nature Climate Change and Proceedings of the National Academy of Science. In 2015 I was awarded the Royal Society (London) Kavli Medal and Lecture (see the lecture at https://royalsociety.org/events/2015/04/continental-loss).
Atomic clocks, combined with precise astronomical measurements, have revealed that the length of a day is suddenly getting longer, and scientists don’t know why.
A record start to summer ice melt in Greenland this year has drawn attention to the northern ice sheet. We will have to wait to see if 2019 continues to break ice-melt records, but in the...
Icebergs breaking off Antarctica, even massive ones, do not typically concern glaciologists. But the impending birth of a new massive iceberg could be more than business as usual for the ...
If you feel that the earth beneath your feet is moving, it’s because it is.
