Journal ArticleDOI
Fast deformation of perennially frozen debris in a warm rock glacier in the Swiss Alps: An effect of liquid water
TL;DR: In this paper, surface movement, internal deformation, and temperature were monitored over 5 years on the Buz North rock glacier, a small rock glacier located at the lower limit of the permafrost belt in the Swiss Alps.
Recent Interannual Variations of Rock Glacier Creep in the European Alps.
Reynald Delaloye,E Perruchoud,Michael Avian,Kaufmann,Xavier Bodin,H Hausmann,Atsushi Ikeda,Andreas Kääb,Andreas Kellerer-Pirklbauer,K Krainer,Christophe Lambiel,D Mihajlovic,B Staub,I Roer,Emmanuel Thibert +14 more
TL;DR: In this article, the authors compared the interannual variations of rock glacier surface motion for 16 landforms monitored for a few years in various parts of the European Alps and found that they are mostly correlated with mean annual ground surface temperature shifts with a delay of a few months.
Journal ArticleDOI
Comparison of geophysical investigations for detection of massive ground ice (pingo ice)
Kenji Yoshikawa,Carl Leuschen,Atsushi Ikeda,Koichiro Harada,Prasad Gogineni,P. Hoekstra,Larry D. Hinzman,Y. Sawada,Norikazu Matsuoka +8 more
TL;DR: In this article, six different geophysical investigations, including ground-penetrating radar, DC resistivity sounding, seismic refraction, very low frequency (VHF) electromagnetic, helicopter borne electromagnetic (HEM), and transient electromagnetic (TEM) techniques, were employed to obtain information on the ice body properties of pingos near Fairbanks, Alaska.
Journal ArticleDOI
Degradation of talus-derived rock glaciers in the Upper Engadin, Swiss Alps
Atsushi Ikeda,Norikazu Matsuoka +1 more
TL;DR: Active and inactive rock glaciers differ from relict rock glaciers in the presence of subsurface permafrost, as indicated by high seismic velocity, high DC resistivity and low bottom temperature of the winter snow cover.
Journal ArticleDOI
Pebbly versus bouldery rock glaciers: Morphology, structure and processes
TL;DR: In the Swiss Alps, pebbly rock glaciers are distinguished from bouldery rock glaciers by the clast size of 15-20 cm in the mean b-axis diameter as mentioned in this paper.
