Natural and societal consequences of climate-forced changes of Jostedalsbreen Ice Cap
Between 19 and 23 March, JOSTICE partners from Norgesguidene, Statkraft, Breheimsenteret and the Western Norway University of Applied Sciences (HVL) completed the final season of fieldwork working from the Steinmannen cabin. While last year’s fieldwork focussed on the upper and flatter regions of the ice cap, this year’s fieldwork aimed to measure along some of the steeper outlet glaciers. As a consequence, travel and data collection was much more challenging this year compared to 2021, both for people, scooters and radars! Through hard work, quite a few ingenious tape repairs and excellent teamwork, we managed to collect measurements in most of the planned regions as well as a couple of improvised ones. All in all, a successful end to the scooter based JOSTICE fieldwork in this region of the ice cap. More to come on the northern regions!
JOSTICE measurements of snow and ice thickness from Steinmannen completed

The JOSTICE 2022 spring field campaign has reached another major step with the completion of snow and ice thickness measurements from the cabin Steinmannen.
