Malin Johansson
Job description
In the Earth Observation group we connect remote sensing with numerical modelling and in-situ data for improved understanding of Arctic sea ice properites and monitoring, and environmental monitoring such as oil spills and harmful algae blooms. The remote sensing work primarily uses synthetic aperture radar (SAR) and optical satellite images. My work primarily focuses on multi-frequency observations.
I'm presently supervising UiT PhD students:
Truls Karlsen (multi-frequency sea ice observations)
Jakub Petříček (permafrost remote sensing observations)

Research interests
Using SAR and optical imagery combined with in-situ data to study oil spill, sea ice and snow. The aim is to detect the oil, sea ice and snow and connect it to the underlaying physics of the material.
