Using satellite technology to study how bogs "breathe" could help build a better picture of the condition of Scotland's peatland, experts have said. New research, published on International Bog Day, demonstrated the potential of measuring bog "breathing" - or peatland surface motions - to monitor the condition of sites, and possibly even carbon emissions from them. The research is a collaboration between NatureScot - which was previously known as Scottish Natural Heritage - the University of the Highlands and Islands, the University of Nottingham, and Forestry and Land Scotland. It used satellite interferometric synthetic aperture radar (InSAR) to map the movement of the ground's surface - a technique developed with University of Nottingham spinout company Terra Motion Ltd.
