The BGS operate an observatory site at Virkisjökull in south-east Iceland, studying the evolution of the glacier and the surrounding landscape and their responses to regional climate.
Sensors at the site are constantly collecting climate and seismic data. Repeated high resolution surveys study how both the glacier and land surface, and the deposits beneath, change over time.
We are using cutting-edge technologies, not used in such a combination anywhere else in the world. These give unique insights into:
Virkisjökull is retreating rapidly, like most glaciers in Iceland. Since 1996, the glacier margin has retreated nearly 500 m, and it appears that this rate has accelerated over the last five years.
Why is this important?
Globally, glaciers and ice sheets help to regulate Earth's climate:

We interpret the combined results of constant monitoring, using automatic systems, plus field surveying of land-surface change, glacier hydrology, and evolution of the shallow subsurface.
