The drainage divides of ice sheets separate the overall glaciated area into multiple sectors.
These drainage basins are essential for partitioning mass changes of the ice sheet, as they …

Land-terminating sectors of the Greenland ice sheet flow faster in summer after surface
meltwater reaches the subglacial drainage system. Speedup occurs when the subglacial …

This study investigates seasonal ice dynamics of Nioghalvfjerdsfjorden or 79° N Glacier, one
of the major outlet glaciers of the North East Greenland Ice Stream. Based on remote …

Growing interest in supraglacial channels, coupled with the increasing availability of high-
resolution remotely sensed imagery of glacier surfaces, motivates the development and …

Supraglacial rivers set efficacy and time lags by which surface meltwater is routed to the
englacial, subglacial, and proglacial portions of ice masses. However, these hydrologic …

Seasonal glacier ice velocities are important for understanding controlling mechanisms of
ice flow. For many Greenlandic glaciers, however, these measurements are limited by low …

We present satellite-derived velocity patterns for the two contrasting melt seasons of 2009–
10 across Russell Glacier catchment, a western, land-terminating sector of the Greenland …

Glacier inventories provide essential baseline information for the determination of water
resources, glacier-specific changes in area and volume, climate change impacts as well as …

While numerous maps of Greenland ice flow velocity exist, most have gaps in coverage
and/or accuracy is limited. We processed a large volume of synthetic aperture radar and …

Airborne radar sounding is difficult in South Greenland because of the presence of englacial
water, which prevents the signal from reaching the bed. Data coverage remains suboptimal …
