A geophysicist whose work has helped to plan space missions and paint a better picture of sea-level rise has been awarded the prize of the Prime Minister of Science.
Professor Kurt Lambeck Received the $ 250,000 Prize in the Parliament Building for a Huge Body
In the 1960s, his early work on describing the Earth's gravity field helped to better plan space missions.
"That was at the time the satellite business started," said Professor Lambeck of the Australian National University
"It was quite natural to see how these satellites could be used for mapping … and then, of course, all these interesting geophysical results came out, and I think at this point I became more of a true scientist than an engineer
"I really switched from a space technologist to a geophysicist."
When he looked deeper, It was obvious that the Earth was changing. The gravitational field was linked to plate tectonics ̵
The next phase of his research helped explain how our planet changes over time Sea level, the movement of the continents, and even the orbits of satellites.
"There is a whole spectrum of variations that go from seconds to the age of the earth."
Professor Lambeck began to understand what that spectrum of variations looked like.
The study of Earth's ice ages helped – and contributed to our understanding of
"The glacier history is one of the elements in this spectrum"
"Antarctic-sized ice sheets [once] sat over North America for example and They do not support the kind of burdens that are associated with them, so they sag beneath them and the crust subsides. "
As the ice melted, the earth's crust began to rise again – very, very slowly, in processes that continue today. 19659002] Over time, the country's position relative to the sea changed. Part of this could be due to the rise in the Earth's crust, while part of it could be due to changes in the volume of the ocean.
"This is the critical contribution we make."
Research has helped shape discussions about sea-level rise due to global warming.
"When the remaining ice sheets in Greenland and the Antarctic melt, sea levels will rise again, and what we do is set the scene for discussion," he said.
"Satellites were built to measure these current deformations, especially to see what happens to Greenland and the Antarctic – but these signals are contaminated by the past [for example glacial rebound from the ice ages]." We can provide the mechanisms to This is happening today, and how much of what is happening today is due to the melting of the ice sheets or the warming of the oceans.
Ensuring the Accuracy of GPS-based Applications
Professor Lambeck's research has also helped inform the GPS systems We rely on smartphone navigation apps, high-tech mining activities, and precision farming.  "Agriculture is increasingly driven by semi-automation," he explained.
