The ice streams feeding the Dotson and Crosson ice shelves are some of the fastest changing in West Antarctica. We use satellite observations to measure the change in ice speed […]
This dataset includes double-difference interferograms derived from TerraSAR-X synthetic aperture radar data acquired at the grounding line downstream of Engelhardt Subglacial Lake on the Gould Coast, Antarctica, in September 2012, […]
An airborne radar survey was flown over the Institute and Moller ice streams in the Weddell Sea sector of West Antarctica in the austral summer of 2010/11 as part of […]
An airborne radar survey was flown as part of the GRADES-IMAGE project funded by BAS over the Antarctic Peninsula, Ellsworth Mountains and Filchner-Ronne Ice Shelf (also including the Evans Ice […]
This is a collection of GPS data from dual-frequency GPS units deployed on the Filchner-Ronne Ice Shelf and adjoining ice streams. Filenames contain ice stream code and, in some cases, […]
SAR-processed two-dimensional radargram data in SEG-Y format acquired from the Institute and Moller ice streams, West Antarctica between mid-December 2010 and mid-January 2011. Data were collected using the British Antarctic […]
This project investigated the ice streams of West Antarctica’s Weddell Sea sector through airborne surveys.
We present a detailed analysis of bed roughness beneath Institute and Möller Ice Streams, west Antarctica, using radio-echo sounding data (RES) acquired in the austral summer of 2010/11. We assess […]
Subglacial bed conditions exert a significant control on ice stream behavior and evolution, and can be characterized by determining bed roughness from FFT analysis of radar-imaged basal reflectors. Here we […]
Laterally continuous subglacial sediments are a necessary component for ice streaming in the modern onset regions of the ice streams draining the Siple Coast of West Antarctica on the basis […]
Antarctica is Earth’s largest and most pristine wilderness. Consequently, it offers an unparalleled natural laboratory for scientific research.
Scientists have discovered a glacier in Antarctica committing “ice piracy” – stealing ice from its neighbour in a phenomenon previously thought to take hundreds or thousands of years.
