The largest delta plain in Earth's history
(Peer reviewed; Journal article, 2019-03-22)Delta plains host heavily populated and extensive agricultural areas with strong anthropogenic overprints on the natural evolution of these important landforms. Furthermore, modern delta plains have formed over a short ... -
Large‐scale regional model biases in the extra‐tropical North Atlantic storm track and impacts on downstream precipitation
(Peer reviewed; Journal article, 2019)Global climate models have circulation biases that the community aims to reduce, for instance through high‐resolution dynamical downscaling. We used the Weather Research and Forecasting model (WRF) to downscale both ... -
Laser excited Li Rydberg atoms in electric and magnetic fields
(Doctoral thesis, 2012-05-09) -
Laser Wake Field Collider
(Journal article; Peer reviewed, 2021)Recently NAno-Plasmonic, Laser Inertial Fusion Experiments (NAPLIFE) were proposed, as an improved way to achieve laser driven fusion. The improvement is the combination of two basic research discoveries: (i) the possibility ... -
Laser-atom Interactions in the Dirac Equation for Hydrogen
(Master thesis, 2018-06-22)The advancements of laser technology make it possible to produce high-energy lasers. It is of interest in many technologies, especially optics, to study how these high-energy lasers interact with atomic or molecular systems. ... -
The last Eurasian Ice Sheets - a chronological database and time-slice reconstruction
(Peer reviewed; Journal article, 2016-10-09)We present a new time-slice reconstruction of the Eurasian ice sheets (British–Irish, Svalbard–Barents–Kara Seas and Scandinavian) documenting the spatial evolution of these interconnected ice sheets every 1000 years from ... -
Last Glacial Maximum environmental conditions at Andøya, northern Norway; evidence for a northern ice-edge ecological “hotspot”
(Journal article; Peer reviewed, 2020)Andøya on the NW coast of Norway is a key site for understanding the Last Glacial Maximum (LGM) in northern Europe. Controversy has arisen concerning the local conditions, especially about the timing and extent of local ... -
A Last Glacial Maximum forcing dataset for ocean modelling
(Journal article; Peer reviewed, 2020)Model simulations of the Last Glacial Maximum (LGM; ∼ 21 000 years before present) can aid the interpretation of proxy records, can help to gain an improved mechanistic understanding of the LGM climate system, and are ... -
Last interglacial sea-level proxies in the glaciated Northern Hemisphere
(Journal article; Peer reviewed, 2022)Because global sea level during the last interglacial (LIG; 130–115 ka) was higher than today, the LIG is a useful approximate analogue for improving predictions of future sea-level rise. Here, we synthesize sea-level ... -
Last-century vegetational changes in northern Europe. Characterisation, causes, and consequences
(Doctoral thesis, 2011-11-04)In the face of recent changes in environmental conditions and climate, longterm studies provide important insights into patterns and processes of vegetational change. In northern Europe, however, long-term studies are rare ... -
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 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 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 ... -
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 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 ...
