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 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 mud-dominated, basin-floor sedimentation of the Gulf of Corinth, Greece: Implications for deep-water depositional processes and controls on syn-rift sedimentation
(Journal article; Peer reviewed, 2022)Syn-rift deep-water muds and mudstones preserve a relatively complete stratigraphic record of tectonic and climatic events. This paper investigates mud-dominated deposits and stratigraphy using core from International Ocean ... -
Late Triassic (Carnian) Palynology of the Northern Barents Sea (Sentralbanken High)
(Master thesis, 2014-06-23)This study is part of a broader palynological investigation of late Middle to Late Triassic, where the main aim is to improve the biostratigraphic resolution by applying palynology. The low abundance of macrofossils (e.g. ... -
Late Triassic (early Carnian) palynology of the shallow stratigraphic core 7830/3-U-1, offshore Kong Karls Land, Northern Barents Sea
(Master thesis, 2016-05-31)This study presents palynostratigraphic and palynofacies analyses from the shallow stratigraphic core 7830/3-U-1, drilled through the Snadd Formation (equivalent to De Geerdalen Formation) offshore Kong Karls Land in the ... -
Late Weichselian (Valdaian) and Holocene vegetation and environmental history of the northern Timan Ridge, European Arctic Russia
(Peer reviewed; Journal article, 2003)Lake and peat deposits from the Timan Ridge, Arctic Russia, were pollen analysed, reconstructing the vegetation history and paleoenvironment since the Last Glacial Maximum (LGM) 20–18,000 years ago. The sites studied are ... -
Late Weichselian relative sea-level changes and glacial history in Hordaland, Western Norway
(Doctoral thesis, 2006-05-19)Two well dated lateglacial relative sea-level curves have been constructed from Hordaland, western Norway, by the isolation basin method. The easternmost curve is based on six basins from the Os area, close to the Younger ... -
A late-Holocene multi-proxy record from the northern Norwegian margin: Temperature and salinity variability
(Journal article, 2016)To elucidate the natural variability of Atlantic and Coastal water, a late-Holocene multi-proxy analysis is performed on a marine sediment core from the northern Norwegian margin. This includes planktic foraminiferal fauna ... -
A late-winter to early-spring temperature reconstruction for southeastern Norway from 1758 to 2006
(Peer reviewed; Journal article, 2007-10)Systematic temperature observations were not undertaken in Norway until the early 19th century, and even then only sporadically. Climate-proxy data may be used to reconstruct temperatures before this period, but until now ... -
Latest Miocene to Late Pliocene Dinoflagellate Cyst Biostratigraphy of the Ocean Drilling Program Hole 642B on the Vøring Plateau
(Master thesis, 2013-07-02)An updated Late Neogene dinoflagellate cyst biozonation of the Norwegian Sea is needed, as it, together with other recent zonations from the Iceland Sea, the eastern North Atlantic and the eastern North Sea (Denmark), will ... -
Latitudinal variability in the Quaternary development of the Eurasian ice sheets—Evidence from the marine domain
(Journal article; Peer reviewed, 2021)Here we present the first compilation of sediment volumes, sedimentation rates, and chronology of Quaternary sediment packages along the entire marine margin of the Eurasian ice sheets (EurIS; British–Irish, Kara–Barents ... -
