Greenland runoff, from ice mass loss and increasing rainfall, is increasing. That runoff, as
discharge, impacts the physical, chemical, and biological properties of the adjacent fjords …

Subglacial hydrological processes at tidewater glaciers remain poorly understood due to the
difficulty in obtaining direct measurements and lack of empirical verification for modelling …

Thinning rates of ice shelves vary widely around Antarctica, and basal melting is a major
component of ice shelf mass loss. In this study, we present records of basal melting at a …

Intensive study of the Greenland Ice Sheet's (GrIS) subglacial drainage has been motivated
by its importance for ice dynamics and for nutrient/sediment export to coastal ecosystems …

Svalbard tidewater glaciers are retreating, which will affect fjord circulation and ecosystems
when glacier fronts become land-terminating. Knowledge of the subglacial topography and …

We report three active subglacial lakes within 2 km of the lateral margin of Isunguata Sermia,
West Greenland, identified by differencing time-stamped ArcticDEM strips. Each lake …

Due to increasing surface melting on the Greenland ice sheet, better constraints on
seasonally evolving basal water pressure and sliding speed are required by models. Here …

We present a new digital elevation model (DEM) of the bed, with a 1 km gridding, of the
Weddell Sea (WS) sector of the West Antarctic Ice Sheet (WAIS). The DEM has a total area …

Spectral roughness offers a significant potential for understanding the evolution of glaciated
landscapes. Here, we present the first roughness study combining a high-resolution (250 to …

We provide high-resolution datasets of Greenland hydrologic outlets, basins, and streams,
and a 1979 through 2017 time series of Greenland liquid water runoff for each outlet …
