We present a highly detailed study of calving dynamics at Tunabreen, a tidewater glacier in Svalbard. A time-lapse camera was trained on the terminus and programmed to capture images every 3 seconds over a 28-hour period in August 2015, producing a h

Basal dynamics of Kronebreen, a fast-flowing tidewater glacier in Svalbard: non-local spatio-temporal response to water input

We evaluate the variability in basal friction for Kronebreen, Svalbard, a fast-flowing tidewater glacier. We invert 3 years (2013–15) of surface velocities at high temporal resolution (generally 11 days), to estimate the changing basal properties o

Publikováno v: Geoscientific Instrumentation, Methods and Data Systems, Vol 8, Pp 113-127 (2019)

Calving is an important process in glacier systems terminating in the ocean and more observations are needed to improve our understanding of the undergoing processes and be able to parameterise calving in larger scale models. Time-lapse cameras are g

A Sliced-3D FDTD approach as an alternative to 2D Ground Penetrating Radar modelling

Autor: Richard Delf, Nicholas R. J. Hulton, Andrew Curtis, Robert Bingham, Antonios Giannopoulos

Publikováno v: 2017 9th International Workshop on Advanced Ground Penetrating Radar (IWAGPR).

Ground penetrating radar (GPR) is a powerful tool for characterisation of the subsurface in a range of applications. Finite-difference time-domain (FDTD) forward modelling is often used to gain a more quantitative understanding of the interaction bet

The relict moraines in Argentine Patagonia archive major expansions of the Patagonian Ice Sheet throughout the Quaternary, and are one of the few terrestrial climate proxies in the middle latitudes of the Southern Hemisphere that extends beyond the l
