Late Glacial and Holocene Glacier Activity in Arctic Norway. Reconstruction of glacier fluctuations using surface exposure dating of moraines and multi-proxy analysis of sediments deposited in distal glacier-fed lakes
(Doctoral thesis, 2014-12-11)Late Glacial and Holocene glacier activity in Arctic Norway was reconstructed based on high-sensitivity 10Be dating of a moraine sequence deposited by the mountain glacier Rødhetta on the island of Arnøya, and a study of ... -
Late Glacial mountain glacier culmination in Arctic Norway prior to the Younger Dryas
(Journal article; Peer reviewed, 2020)Climate changes during the Late Glacial period (LG; 15-11 ka) as recorded in Greenland and Antarctic ice cores show a bipolar pattern. Between 14.5 ka and 13 ka ago, the northern latitudes experienced the Bølling/Allerød ... -
Late Holocene canyon-carving floods in northern Iceland were smaller than previously reported
(Journal article; Peer reviewed, 2021)Catastrophic floods have formed deep bedrock canyons on Earth, but the relationship between peak discharge and bedrock erosion is not clearly understood. This hinders efforts to use geological evidence of these cataclysmic ... -
Late Holocene Relative Sea-Level Reconstructions in Evenes, North Norway.
(Master thesis, 2023-06-02) -
Late Holocene surface ocean conditions of the Norwegian Sea (Vøring Plateau)
(Peer reviewed; Journal article, 2003-06-04)Late Holocene sea surface ocean conditions of the eastern Norwegian Sea (Vøring Plateau) are inferred from planktic stable isotopes and planktic foraminiferal assemblage changes in cores JM97-948/2A and MD95-2011 (66.97°N, ... -
Late iron age economies of Mount Kenya region A case study of Kiburu, Kangai and Kanyua archaeological sites
(Master thesis, 2006)Earlier Iron Age investigations in Kenya concentrated on the Lake Victoria Basin and the coast of Kenya, mainly focusing on origins and technological aspects of iron, with brief statements on economies. The pioneering work ... -
The late Iron Age Worldwiev and the Concept of “Utmark”
(Universitetet i Bergen, Arkeologiske Skrifter (UBAS) International, Chapter; Peer reviewed, 2005) -
Late Jurassic to Late Cretaceous canyons on the Måløy Slope: Source to sink fingerprints on the northernmost North Sea rift margin, Norway
(Journal article; Peer reviewed, 2021)The Måløy Slope is a key area for studying the connection between onshore and offshore geology of South Norway. It has functioned as an area of bypass, erosion and deposition between the Norwegian mainland source area and ... -
Late Neogene dinoflagellate cyst and acritarch biostratigraphy for Ocean Drilling Program Hole 642B, Norwegian Sea
(Peer reviewed; Journal article, 2017-01)The Arctic is a critical region in the current and past global climate system. One major challenge for investigating the geological history of the Arctic is the establishment of a rigorous chronology. To get better insights ... -
Late Neoproterozoic–Cambrian magmatism in Dronning Maud Land (East Antarctica): U–Pb zircon geochronology, isotope geochemistry and implications for Gondwana assembly
(Journal article; Peer reviewed, 2020)Dronning Maud Land (DML) is a key area for the better understanding of the geotectonic history and amalgamation processes of the southern part of Gondwana. Here, we present comprehensive new zircon U–Pb–Hf–O, whole-rock ... -
Late Onset Myasthenia Gravis Is Associated with HLA DRB1*15:01 in the Norwegian Population
(Peer reviewed; Journal article, 2012-05-09)Background: Acquired myasthenia gravis (MG) is a rare antibody-mediated autoimmune disease caused by impaired neuromuscular transmission, leading to abnormal muscle fatigability. The aetiology is complex, including genetic ... -
A late Paleoproterozoic (1.74 Ga) deep-sea, low-temperature, iron-oxidizing microbial hydrothermal vent community from Arizona, USA
(Journal article; Peer reviewed, 2021)Modern marine hydrothermal vents occur in a wide variety of tectonic settings and are characterized by seafloor emission of fluids rich in dissolved chemicals and rapid mineral precipitation. Some hydrothermal systems vent ... -
Late Pleistocene songbirds of Liang Bua (Flores, Indonesia); the first fossil passerine fauna described from Wallacea
(Peer reviewed; Journal article, 2017-08-17)Background: Passerines (Aves: Passeriformes) dominate modern terrestrial bird communities yet their fossil record is limited. Liang Bua is a large cave on the Indonesian island of Flores that preserves Late Pleistocene–Holocene ... -
Late Plio-Pleistocene evolution of the Eurasian Ice Sheets inferred from sediment input along the northeastern Atlantic continental margin
(Journal article; Peer reviewed, 2022)High-latitude marine sediment archives may contain information about the configuration and dynamics of former ice sheets, paleoclimate and the intensity of glacial erosion and uplift in catchment areas. Compiling information ... -
Late Quaternary chironomid community structure shaped by rate and magnitude of climate change
(Journal article; Peer reviewed, 2021)Much is known about how climate change impacts ecosystem richness and turnover, but we have less understanding of its influence on ecosystem structures. Here, we use ecological metrics (beta diversity, compositional disorder ... -
Late Quaternary dynamics of Arctic biota from ancient environmental genomics
(Journal article; Peer reviewed, 2021)During the last glacial–interglacial cycle, Arctic biotas experienced substantial climatic changes, yet the nature, extent and rate of their responses are not fully understood1,2,3,4,5,6,7,8. Here we report a large-scale ... -
Late Quaternary environmental reconstruction using foraminifera and sedimentary stratigraphy from Kapp Ekholm, Svalbard
(Master thesis, 2014-10-19)SUMMARY The Kapp Ekholm sedimentary sections is a key location for our present understanding of the two last glacial cycles on western Svalbard. Its long sedimentary history (MIS 6 to present) and its position almost at ... -
