This year we took part in a scientific expedition to the southwestern region of the Greenland ice sheet. Representing the Geological Survey of Denmark and Greenland (GEUS), and in collaboration with the Institute for Marine and Atmospheric Research (IMAU), we serviced instruments and stakes placed at 10 different sites on the ice sheet. We accessed the remote sites, up to 140 km into the ice sheet, by Air Greenland helicopter.
The scientific instruments by GEUS and IMAU monitor the interaction between the atmosphere and the ice sheet. In other words, they determine how much ice melts, and what is causing the melt: which combination of warm weather, solar radiation, strong winds, etc. The GEUS instruments are part of the measurement networks of the Greenland Analogue Project (GAP) and the Programme for Monitoring of the Greenland Ice Sheet (PROMICE). We even installed 4 of our own draw-wire ice ablation trackers (DWIATs) – more about that in an upcoming news item.
The measurements are taken along the iconic K-transect, where ice sheet monitoring already began in 1990(!). The longer the times series, the more valuable it gets. Long climate records provide much needed context for measurements in individual years: if there is 5 m of ice melt – is it a lot (above average) or not?
Even though taking measurements over many years is crucial for climate science, it is not always an attractive option for funding agencies. So if you’d like to financially support the monitoring activities along the K-transect, it could make a large difference!
The transect, consisting of 10 instrumented sites, is located along the western slope of the Greenland ice sheet, from the low-elevation ice sheet margin, up to an elevation of 1840 m above sea level. Both surface mass balance and weather/radiation observations are made, to be able to quantify ice loss, and to explain which processes (such as atmospheric warming) dominate this mass transfer from the ice sheet to the oceans.
The end of an era might be approaching as obtaining funding for the monitoring is becoming increasingly difficult. Even though the measurement time series is becoming more important with each added year – in Greenland there is nothing that compares. And even though many important scientific publications have relied on these data in the past.
That’s why SKB, the primary funder of GEUS’s efforts at the K-transect for the past 13 years, requested Greenland Guidance to construct a video with the aim to make more people aware of the climate and ice sheet science being done in Greenland, and to attract additional funding.
