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 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 ... -
Late-syn- to post-rift salt tectonics on wide rifted margins—Insights from geodynamic modeling
(Journal article; Peer reviewed, 2022)Rifted margins are often associated with widespread and thick evaporite (salt) deposits and pronounced salt tectonics. The largest salt basins formed during the latest stages of rifting, immediately prior to continental ... -
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 ... -
Layer parallel shortening and cataclastic flow by fractures in the Permian Kapp Starostin Formation, Mediumfjellet, Spitsbergen
(Master thesis, 2015-06-01)This study presents a structural analysis, from macro- to micro-scale, of the Permian carbonates and spiculites of the Kapp Starostin Formation. The analysis was conducted to better understand the fracture development and ... -
Leaving a plastic legacy: Current and future scenarios for mismanaged plastic waste in rivers
(Journal article; Peer reviewed, 2023)Mismanaged plastic waste (MPW) entering the riverine environment is concerning, given that most plastic pollution never reaches the oceans, and it has a severe negative impact on terrestrial ecosystems. However, significant ... -
Lessons from a high-CO2 world: an ocean view from ∼ 3 million years ago
(Journal article; Peer reviewed, 2020)A range of future climate scenarios are projected for high atmospheric CO2 concentrations, given uncertainties over future human actions as well as potential environmental and climatic feedbacks. The geological record ... -
Lidarskanning av skredutsatte skråninger i Hardanger
(Master thesis, 2016-09-01)Målet med dette masterprosjektet var å undersøke hvordan bakkebasert lidarskanning kan brukes til å kvantifisere og overvåke skredutsatte skråninger. Videre har det blitt undersøkt om det er mulig å volumestimere ... -
LIME: Software for 3-D visualization, interpretation, and communication of virtual geoscience models
(Peer reviewed; Journal article, 2019-01-10)The use of three-dimensional (3-D), photo-textured representations of topography from laser scanning and photogrammetry is becoming increasingly common across the geosciences. This rapid adoption is driven by recent ... -
Limited exchange between the deep Pacific and Atlantic oceans during the warm mid-Pliocene and Marine Isotope Stage M2 “glaciation”
