About a decade ago a consortium of scientific and commercial organisations led by SKB in Sweden drilled a borehole in the bedrock underneath the Greenland ice sheet. Their goal: to quantify the level of interaction between the ice sheet and the groundwater below. To achieve this they drilled a 651 m long borehole angled underneath the ice sheet and equipped it with instruments. It is the first ever borehole drilled underneath an ice sheet – a truly unique project.
Recently, SKB asked Greenland Guidance to perform instrument maintenance to ensure the continuation of the time series during a period when travel to Greenland is complicated by the COVID-19 pandemic. We gratefully accepted the task. While on site, we saw an opportunity to also shoot some drone footage.
The measurements taken in the borehole form a long, uninterrupted, and scientifically surprising time series. With the help of scientists from the University of Montana and others, SKB has written up a manuscript that is currently under review in a scientific journal. Greenland Guidance helped with the interpretation of the borehole data in terms of ice melt and movement, and is proud collaborator on the study.
