We present velocity observations of a glacier outlet in Vatnajökull, Iceland, deduced from interferometric SAR (InSAR) data obtained during the ERS1/2 tandem mission in 1995–2000. More than a 50%...
Interaction between ice sheet dynamics and subglacial lake circulation:a coupled modelling approach

Subglacial lakes in Antarctica influence to a large extent the flow of the ice sheet. In this study we use an idealised lake geometry to study this impact. We employ a) an improved three-dimensional f...

waters of the lake. Bacterial density is two- to sevenfold higher in accretion ice than the overlying glacial ice,
implying that Lake Vostok is a source of bacterial carbon beneath the ice sheet. Phy...
