Automated classification of debris-covered glaciers combining optical, SAR and topographic data in an object-based environment
Robson, Benjamin Aubrey; Nuth, Christopher; Dahl, Svein Olaf; Hölbling, Daniel; Strozzi, Tazio; Nielsen, Pål Ringkjøb (Peer reviewed; Journal article, 2015-12)Satellite imagery is increasingly used to monitor glacier area changes and create glacier inventories. Robust and efficient pixel-based band ratios have proven to be accurate for automatically delineating clean glacier ... -
Early Holocene occurrence of loess in Folldal, east-central southern Norway: Identification, origin and palaeoclimatic significance
Dahl, Svein Olaf; Nielsen, Pål Ringkjøb (Journal article; Peer reviewed, 2024)Identified for the first time in Norway, windblown yellowish-brown dust in Folldal, east-central southern Norway, fulfils physical and geochemical criteria for sensu stricto loess, including a high carbonate content. Two ... -
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 ... -
Holocene storminess and climate change in Lofoten and Vesteralen, northern Norway
Nielsen, Pål Ringkjøb (Doctoral thesis, 2016-06-08)This thesis investigates Holocene storminess and climate change reconstructed from lacustrine sediments from the Lofoten-Vesterålen archipelago in northern Norway (68–69°N, 12–16°E). The present thesis consists of an ... -
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 ... -
Palaeoclimatic and regional implications of Older Dryas and Younger Dryas local glacier activity in the low-Arctic valley Finnkongdalen, Andøya, northern Norway
Jansen, Henrik Løseth; Dahl, Svein Olaf; Linge, Henriette; Bakke, Jostein; Nielsen, Pål Ringkjøb; Kvisvik, Bjørn Christian (Journal article; Peer reviewed, 2023)Continuous glacier margin and equilibrium-line altitude fluctuations of a former glacier on central Andøya, northern Norway, are reconstructed during the Lateglacial based on moraines and AMS 14C-dated sediments from the ... -
Spatial Variability in Patterns of Glacier Change across the Manaslu Range, Central Himalaya
Robson, Benjamin Aubrey; Nuth, Christopher; Nielsen, Pål Ringkjøb; Girod, Luc Maurice Ramuntcho; Hendrick, Marijn; Dahl, Svein Olaf (Peer reviewed; Journal article, 2018-02-13)This study assesses changes in glacier area, velocity, and geodetic mass balance for the glaciers in the Manaslu region of Nepal, a previously undocumented region of the Himalayas. We studied changes between 1970 (for ...
