– We need to understand how glaciers are shrinking in order to better adapt to climate change impacts such as changes to water supply, landslides and avalanches, says Prof. Andreas Kääb, a glacier expert from the University of Oslo in Norway.
Southern Norway has been hit several times by exceptionally heavy rain and following flooding in October 2017. The cloud cover during such rain events makes it difficult to get an overview over the flooded areas from air and space. But the new European Sentinel 1A and 1B radar satellites can look through the clouds, and give an accurate and timely overview over the affected areas
There are many glaciers in the Norwegian landscape. They are at risk of decline drastically and perhaps disappearing due to a warmer climate. Especially exposed are the glaciers in Northern Norway and the smallest glaciers. Interview with Solveig Havstad Winsvold in the newspaper Morgenbladet in the column 'The doctor answers' in June.
Cross disciplinary approaches using both seismic recordings and satellite observations of glaciers provide data to estimate glacier frontal ablation rates. This provides new insight into the processes that control dynamic mass loss of glaciers into the sea. Such cross disciplinary approaches can be valuable in climate research.
The Copernicus Sentinel-1 and Sentinel-2 satellites have found signs of an ongoing glacier dislocation between two recent massive ice avalanches in Tibet.
Sentinels team up reporting 12. October.
Recently, a Danish-Norwegian research team re-processed thousands of aerial photos into 3D Digital Elevation Models (DEM) surrounding the entire coastline of Greenland. The new data extends the precise geometric record of Greenland glacier margins to the late 1970s and 80s and can be used to quantify the decline in the ice mass, for example. The data is freely available to the public domain.
En ny studie basert på eldre foto viser at innlandsisen på Grønland er i rask retur. Det har lenge vore usikkert hvor mye bremasse Grønlandsisen har tapt og hvor raskt nedsmeltingen skjer. Etter å ha sammenlignet gamle og nye foto og satellittdata har forskerne nå fått mer kunnskap. Studien er publisert i Nature, og en av medforfatterne er Christopher Nuth, Institutt for geofag.
PhD Luc Girod from Department of Geosciences recently received the award for best paper at this year SMPR conference within geomatics, environmental monitoring and satellite data. The Conference was held at the University of Tehran in November.
Isbreer, snø og permafrost på verdens høyeste fjell gjennomgår store endringer, noe som kan gi store konsekvenser for både mennesker og miljø. En tverrfaglig forskergruppe har sett på hva som er drivere av klimaendringer i alpine områder, og hva risiko som følger med endringen. Dette har resultert i boken The High-Mountain Cryosphere.
Glaciologists and other scientists and students from around the world met in Kathmandu in Nepal in the first week in March 2015. The venue was the International Symposium on Glaciology in High Mountain Asia. PhD student Désirée Treichler from the Department of Geosciences attended the academic program, and received a prize for best student presentation for her presentation about hydrological consequences of glacier mass changes in high mountain Asia.
