Stochastic ice stream dynamics. [PDF]
Proc Natl Acad Sci U S A, 2016 Significance Ice streams form the backbone of the flow field of ice sheets. They are known to exhibit a complex spatiotemporal dynamics, which is largely not well understood. Understanding the controls on such dynamics is crucial to sea level change projections as well as to the interpretation of paleorecords.

Antarctic palaeo-ice streams [PDF]
Earth-Science Reviews, 2012 We review the geomorphological, sedimentological and chronological evidence for palaeo-ice streams on the continental shelf of Antarctica and use this information to investigate basal conditions and processes, and to identify factors controlling grounding-line retreat.

Modeling the elastic transmission of tidal stresses to great distances inland in channelized ice streams [PDF]
, 2014 Geodetic surveys suggest that ocean tides can modulate the motion of Antarctic ice streams, even at stations many tens of kilometers inland from the grounding line.

The role of subtemperate slip in thermally driven ice stream margin migration [PDF]
, 2018 The amount of ice discharged by an ice stream depends on its width, and the widths of unconfined ice streams such as the Siple Coast ice streams in West Antarctica have been observed to evolve on decadal to centennial timescales.

Englacial Pore Water Localizes Shear in Temperate Ice Stream Margins [PDF]
, 2019 The margins of fast‐moving ice streams are characterized by steep velocity gradients. Some of these gradients cannot be explained by a temperature‐dependent viscosity alone.

Flow and retreat of the Late Quaternary Pine Island-Thwaites palaeo-ice stream, West Antarctica [PDF]
, 2010 Multibeam swath bathymetry and sub-bottom profiler data are used to establish constraints on the flow and retreat history of a major palaeo-ice stream that carried the combined discharge from the parts of the West Antarctic Ice Sheet now occupied by the ...

A geomorphological overview of glacial landforms on the Icelandic continental shelf [PDF]
, 2009 The availability of a bathymetric database that covers about 80% of the Icelandic shelf has made it possible to produce a geomorphological map of the glacial landforms.

Footprint of the Baltic Ice Stream: geomorphic evidence for shifting ice stream pathways
Boreas, 2023 The Baltic Ice Stream, a large fast‐flowing sector of the last Fennoscandian Ice Sheet that occupied the present‐day Baltic Sea basin, was first conceptualized in the earliest days of glacial geological research in Scandinavia. Landform and sedimentological evidence from the terrestrial margins support the concept and numerical ice‐sheet models ...

, 2021 <div>Ice streams are the arteries through which a large fraction of the ice lost from Antarctica is discharged. With the introduction of "higher order" mechanics, the representation of ice streams in ice sheet models appears to have become more robust, eliminating previously ubiquitous grid effects.
