Field measurements of sintering after fracture of snowpack weak layers
(Journal article, 2006)This research documents two cases where field workers unintentionally fractured a snowpack weak layer, but no avalanche released. Measurements from before and after the fractures provide unique data sets on the temporal ... -
Integrating spatial patterns into a snow avalanche cellular automata model
(Journal article, 2005)Snow avalanches are a major mountain hazard that kills hundreds of people and causes millions of dollars in damage worldwide annually. Yet, the relationship between the well-documented spatial variability of the snowpack ... -
Ocean-Ionosphere Disturbances Due To the 15 January 2022 Hunga-Tonga Hunga-Ha'apai Eruption
(Peer reviewed; Journal article, 2023) -
Peatland Volume Mapping over Resistive Substrates with Airborne Electromagnetic Technology
(Peer reviewed; Journal article, 2019)Despite the importance of peatlands as carbon reservoirs, a reliable methodology for the detection of peat volumes at regional scale is still missing. In this study we explore for the first time the use of Airborne ... -
Snow thickness profiling on Antarctic sea ice with GPR—Rapid and accurate measurements with the potential to upscale needles to a haystack
(Peer reviewed; Journal article, 2017)Snow thickness on sea ice is a largely undersampled parameter yet of importance for the sea ice mass balance and for satellite-based sea ice thickness estimates and thus our general understanding of global ice volume change. ... -
Some giant submarine landslides do not produce large tsunamis
(Peer reviewed; Journal article, 2017)Landslides are the second-most important cause of tsunamis after earthquakes, and their potential for generating large tsunamis depend on the slide process. Among the world's largest submarine landslides is the Storegga ...
