Antarctic photo science archive unlocked

The photo expeditions were run out of Deception Island, a flooded caldera in the peninsula's north 



UK scientists are comparing the images with newly acquired data sets to assess the changes that have occurred in some of the region's 400-plus glaciers. 

The old and modern information has to be very carefully aligned if it is to show up any differences reliably. 

And that is a big challenge when snow and ice obscure ground features that might otherwise act as visual anchors. 

But the researchers from the British Antarctic Survey (BAS), Newcastle University and University of Gloucestershire believe they are cracking the problem. 

"We want to use these pictures to work out volume and mass-balance changes in the glaciers through time," explained Dr Lucy Clarke from the University of Gloucestershire.
