Opportunity summary

Official occupation: ph.d., naturvidenskab og teknik. Employment conditions: Almindelige vilkår. Employer CVR: 55145016. Primary career market: Public Sector, Education & Impact (employer-sector evidence). Would you like to investigate how Greenland's firn has changed over the past 25 years using airborne radar? About the position This PhD project will use airborne radar data collected over the Greenland Ice Sheet since the early 1990s to reconstruct how the near-surface firn layer has changed over time. As melt intensity on the ice sheet has increased dramatically in recent decades, the firn (compacted snow that covers most of the ice sheet) has been fundamentally altered. Understanding these changes is critical for projecting future sea-level rise and the ice sheet's capacity to store meltwater. You will analyze airborne radar data collected since the early 1990s, focusing on how the radar signal from the near-surface has evolved over a 25-year period. This will allow you to map long-term changes in firn properties, including the expansion of ice slabs and ice layers affecting the firn’s meltwater storage at regional scale across Greenland. Where feasible, you will also map englacial channels, drainage pathways that connect surface meltwater to the ice sheet bed, and where water input influences ice dynamics and ultimately the rate of mass loss from the ice sheet1 …
