Iskjernene blir målt, veid, pakket, merket og lagret i en fryser, slik at vi kan ta de med tilbake til Tromsø for nærmere analyse. Iskjernenene inneholder også verdifull informasjon som er til hjelp når vi analyserer data fra radarene.

(EN) At each ice rise we drill a short ice core (20m deep), to obtain a climate record over the past couple of decades. Each years snow accumulation is buried and compacted into firn and eventually to ice after approximately 100 years. Each drilling recovers about 0.5m of core to the surface, so drilling 20m is a full day´s work.
The ice cores are measured, weighed, bagged, labeled and stored in a freezer so that we can transport them back to Tromsø for further analysis. The ice cores also contains valuable information that is helpful when analyzing the radar data.
