One of the advantages of having very frequent ESA Envisat SAR imagery in the Antarctic is being able to keep a close eye on large icebergs that might cause problems such as restricting access, impact on wildlife or navigational hazard. Add to that list the consequences of hitting an iceshelf, especially when it is home to one of your bases, and it’ s a good idea to keep an eye open.
One such iceberg, lovingly named the B15K, has been loitering around the Brunt iceshelf over the past couple of weeks. Any risk to the Halley base now appears to have passed, but the regular images were a useful part of the monitoring in place to track any changes to the Brunt.
