In the news: In early November we could read an article about iceflow in the Artic published on the news section for the ESA webpages. It describes the research carried out in the ICEFLOW project with Bas Altena and Andreas Max Kääb, Dept. of Geosciences.

A new methodology to combine heaps of satellite images allows researchers from University of Oslo with colleagues to create a complete time series of glacier movement. To demonstrate the methodology, they created a map of ice flow every month, over several years, covering several mountain ranges in Southern Alaska and Canada. Once created, the dataset revealed several sudden glacier speed-ups and slow-downs.

The American Geophysical Union has had recently its fall meeting, 10-14. December in Washington DC. Researcher in geomatics and remote sensing, Bas Altena was here presenting his research on circulation patterns of icebergs in an icy fjord of Greenland. This is the first presentation of ongoing research conducted in the project ICEFLOW.

En fersk doktor i geomatikk fra Universitetet i Oslo, Bas Altena, har fått et postdoc-stipend fra European Space Agency (ESA) Living Planet Fellowship program. Med dette stipendet vil han undersøke nye måter å utnytte satellittdata fra Copernicus-programmet i kombinasjon med andre satellitter for å forstå raske endringer i kryosfæren.
