Two papers have recently been accepted by Annals of Glaciology: The paper On the potential of hand-held GPS tracking of fjord ice features for remote-sensing validation, by Postdoc Jean Negrel, Sebastian Gerland, Anthony Doulgeris, Tom Rune Lauknes and Line Rouyet. And the paper Can we extend local sea-ice measurements to satellite scale? An example from the N-ICE2015…
Wolfgang Dierking and his colleague Jakob Griebel from the Alfred Wegener Institute (AWI) published a paper in “Remote Sensing” on the improved detection of narrow deformation structures in sea ice (with Jakob as first author). The major idea is to avoid blurring of discontinuities in the field of sea ice drift. Abstract: Retrievals of sea…
The article “Sea ice local surface topography from single-pass satellite InSAR measurements: a feasibility study” by Wolfgang Dierking, Oliver Lang and Thomas Busche has been published in the journal The Cryoshpere. Abstract: Quantitative parameters characterizing the sea ice surface topography are needed in geophysical investigations such as studies on atmosphere–ice interactions or sea ice mechanics.…
The paper “Impact of data assimilation on Eulerian versus Lagrangian estimates of upper ocean transport” by Ann Kristin Sperrevik, Johannes Röhrs and Kai Håkon Christensen at the Norwegian Meteorological Institute has recently been accepted in the Journal of Geophysical Research: Oceans. Abstract: Using four-dimensional variational analysis, we produce an estimate of the state of a…
