The Power of Swath Altimetry
A new technique in processing data from the Cryosat spacecraft will allow researchers to assess larger regions of ice sheets in Antarctica and Greenland. The technique is known as swath altimetry.
"Swath altimetry will totally change the way scientists are able to study some phenomena" says Dr Noel Gourmelen from Edinburgh University, UK.
"The temporal and spatial improvements mean that if we have a surge in a glacier, it now makes it much easier to look at where that event initiated. Did the whole glacier start moving at once? Or did the change start at the ocean, meaning the ocean was having an impact on the glacier? Or perhaps it was further back, meaning different processes were involved. Now, we're better able to trace the history and the causes of the surge," he told BBC News.
