Estimating the volume of the 1978 Rissa quick clay landslide in Central Norway using historical aerial imagery
Robson, Benjamin Aubrey; Hölbling, Daniel; Nielsen, Pål Ringkjøb; Koller, Max (Journal article; Peer reviewed, 2022)Quick clay is found across Scandinavia and is especially prominent in south-eastern and central Norway. Quick clay is prone to failure and can cause landslides with high velocities and large run-outs. The 1978 Rissa landslide ... -
Glacier thinning, recession and advance, and the associated evolution of a glacial lake between 1966 and 2021 at Austerdalsbreen, western Norway
Seier, Gernot; Abermann, Jakob; Andreassen, Liss Marie; Carrivick, Jonathan L.; Kielland, Pål Hage; Löffler, Karina; Nesje, Atle; Robson, Benjamin Aubrey; Røthe, Torgeir Opeland; Scheiber, Thomas; Winkler, Stefan; Yde, Jacob Clement (Journal article; Peer reviewed, 2023)The Jostedalsbreen is the largest ice cap in Norway and mainland Europe. Rapid retreat of many of its outlet glaciers since the 2000s has led to the formation of several glacial lakes. Processes causing the formation and ... -
An integrated deep learning and object-based image analysis approach for mapping debris- covered glaciers
Thomas, Daniel Jack; Robson, Benjamin Aubrey; Racoviteanu, Adina E. (Journal article; Peer reviewed, 2023)Evaluating glacial change and the subsequent water stores in high mountains is becoming increasingly necessary, and in order to do this, models need reliable and consistent glacier data. These often come from global ... -
Intensified Late-Holocene aeolian activity in Vesterålen, northern Norway – increased storminess or human impact?
Nielsen, Pål Ringkjøb; Dahl, Svein Olaf; Prestegård, Ingvild Skodvin; Vasskog, Kristian; Robson, Benjamin Aubrey (Journal article; Peer reviewed, 2024)This study reconstructs Mid- to Late-Holocene aeolian activity based on lacustrine sediments from a small pond, Nøkktjønna, situated ~1.5 km northeast from the coast, and stratigraphical investigations of coastal dunes at ... -
Long‐term impact of the proglacial lake Jökulsárlón on the flow velocity and stability of Breiðamerkurjökull glacier, Iceland
Baurley, Nathaniel; Robson, Benjamin Aubrey; Hart, Jane K. (Journal article; Peer reviewed, 2020)Proglacial lakes are becoming ubiquitous at the termini of many glaciers worldwide due to continued climate warming and glacier retreat, and such lakes have important consequences for the dynamics and future stability of ... -
Monitoring glacial lake outburst flood susceptibility using Sentinel-1 SAR data, Google Earth Engine, and persistent scatterer interferometry
Wangchuk, Sonam; Bolch, Tobias; Robson, Benjamin Aubrey (Journal article; Peer reviewed, 2022)Continuous monitoring of glacial lakes, their parent glaciers and their surroundings is crucial because possible outbursts of these lakes pose a serious hazard to downstream areas. Ongoing climate change increases the risk ... -
A pan-Himalayan test of predictions on plant species richness based on primary production and water-energy dynamics
Bhatta, Kuber Prasad; Robson, Benjamin Aubrey; Suwal, Madan Krishna; Vetaas, Ole Reidar (Journal article; Peer reviewed, 2021)Spatial variation in plant species diversity is well-documented but an overarching first-principles theory for diversity variation is lacking. Chemical energy expressed as Net Primary Production (NPP) is related to a ... -
