(1) A surge of the Austfonna ice cap, Svalbard, promoted by a hydro-thermodynamic feedback to summer melt
\nSpeaker: Dr. Thorben Dunse (University of Oslo, Norway)
\nAbstract:
\n Dynamic feedback processes have the potential to significantly alter glacier response to climate change. Here we present continuous GPS measurements and satellite synthetic-aperture radar-based velocity maps from Basin-3, the largest drainage basin of the Austfonna ice cap, Svalbard. Our observations demonstrate strong links between surface-melt and multiannual ice-flow acceleration that culminated in a large-scale dynamic instability, termed glacier surge. The resulting iceberg discharge and the seawater displacement by the terminus advance highlight the importance of dynamic mass loss for glacier mass balance and sea-level rise.<\/p>\n
(2) Permafrost mapping using satellite data
\nSpeaker: Dr. Sebastian Westermann (University of Oslo, Norway)
\nAbstract:
\n Permafrost is a subsurface phenomenon which can not directly measured by remote sensing technologies. Up to now, remote sensing of permafrost has therefore been restricted to the interpretation of surface information obtained from satellites, such as vegetation, surface characteristics or surface motion. We present a new approach which employs remote sensing data as input for subsurface thermal models and can hence deliver the physical variables characterizing the ground thermal state, in particular ground temperature. We present and assess different modeling schemes, which can be used to map permafrost from local to global scale.<\/p>\n","protected":false},"excerpt":{"rendered":"
