- Geology, Environmental Science
- 1 July 2005
Morphological interpretation of regional and detailed bathymetric data sets on the 2500-km-long Norwegian shelf from the North Sea (57°N) to Svalbard (80°N) has revealed a dynamic ice-flow pattern…
BedMachine v3: Complete Bed Topography and Ocean Bathymetry Mapping of Greenland From Multibeam Echo Sounding Combined With Mass Conservation

- Environmental ScienceGeophysical Research Letters
- 1 November 2017
A new compilation of Greenland bed topography that assimilates seafloor bathymetry and ice thickness data through a mass conservation approach is presented, yielding major improvements over previous data sets, particularly in the marine‐terminating sectors of northwest and southeast Greenland.
Dynamics of the Late Weichselian ice sheet on Svalbard inferred from high‐resolution sea‐floor morphology

A process-based sedimentological analysis of Upper Ordovician glacial-marine rocks in Africa suggests that full glaciation of the continental shelf started in the late extraordinarius Zone of the…
Assemblages of submarine landforms produced by tidewater glaciers in Svalbard
- D. Ottesen, J. Dowdeswell
- Geology, Environmental Science
- 1 March 2006
[1] High-resolution swath bathymetry from the marine margins of several Svalbard tidewater glaciers shows an assemblage of submarine landforms that is probably linked to glacier surging. These…
Investigations of the form and flow of ice sheets and glaciers using radio-echo sounding
- J. Dowdeswell, S. Evans
- Environmental Science, Geology
- 1 October 2004
Radio-echo sounding (RES), utilizing a variety of radio frequencies, was developed to allow glaciologists to measure the thickness of ice sheets and glaciers. We review the nature of electromagnetic…
