Aktuelle aktiviteter

Fimbulisen - fra topp til tå

Dette prosjektet ser på vekselvirkningen mellom havet og innlandsisen i Dronning Maud Land.

MEOP

Dette prosjektet bruker sel til å samle inn data fra havet. Blant annet har vi brukt dette til å studere havet foran Fimbulisen og langs kysten av Dronning Maud Land.

Eksperimenter i roterende tank

Nedskaleringer av havstrømmer i en roterende tank brukes til å studere hvordan virvler sprer salt og varme.
