A 1.3-Myr palaeoceanographic record from the continental margin off Dronning Maud Land, Antarctica
Forsberg, Carl Fredrik; Løvlie, Reidar; Jansen, Eystein; Solheim, Anders; Sejrup, Hans Petter; Lie, Hans Erik (Peer reviewed; Journal article, 2003-09-15)A 12.5 m long core was retrieved from the continental margin off Dronning Maud Land, Antarctica. Magnetostratigraphy, stable isotopes, 14C accelerator mass spectrometer and amino acid analyses indicate a continuous sediment ... -
Arctic Holocene proxy climate database – New approaches to assessing geochronological accuracy and encoding climate variables
Sundqvist, H.S.; Kaufmann, Darrell; MaKay, Nickholas; Axford, Y.; Balascio, Nickholas; Briner, Jason P.; Cwynar, L.C.; Sejrup, Hans Petter; Subetto, D.A.; Andrews, J.T.; Bakke, Jostein; Birks, Harry John Betteley; Brooks, S.J.; Vernal, A.E.; Jennings, A.E.; Ljungvist, K.M.; Rûhland, K.M.; Saenger, C.; Smol, J.P.; Viau, A.E. (Peer reviewed; Journal article, 2014-08-29)We present a systematic compilation of previously published Holocene proxy climate records from the Arctic. We identified 170 sites from north of 58° N latitude where proxy time series extend back at least to 6 cal ka (all ... -
Eight-hundred-year temperature variability from the Norwegian continental margin and the North Atlantic thermohaline circulation
Kristensen, Dorthe Klitgaard; Sejrup, Hans Petter; Haflidason, Haflidi; Berstad, I. M.; Mikalsen, G. (Journal article, 2004-04-17)Four cores raised from the eastern Norwegian Sea and adjacent Norwegian fjords at sites influenced by Atlantic water have been investigated. Oxygen isotope analyses in benthic and planktonic foraminifera are used as a proxy ... -
Latitudinal variability in the Quaternary development of the Eurasian ice sheets—Evidence from the marine domain
Hjelstuen, Berit Oline Blihovde; Sejrup, Hans Petter (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 ... -
NE Atlantic continental slope stability from a numerical modeling perspective
Bellwald, Benjamin; Urlaub, Morelia; Hjelstuen, Berit Oline Blihovde; Sejrup, Hans Petter; Sørensen, Mathilde B.; Forsberg, Carl Fredrik; Vanneste, Maarten (Peer reviewed; Journal article, 2019-01)Trough mouth fans are environments characterized by high sediment supply during glacial stages and the occurrence of large-scale instabilities. The geological record indicates that several of these environments have failed ... -
Palaeo-productivity record from Norwegian Sea enables North Atlantic Oscillation (NAO) reconstruction for the last 8000 years
Becker, Lukas; Sejrup, Hans Petter; Hjelstuen, Berit Oline Blihovde; Haflidason, Haflidi; Kjennbakken, Heidi; Werner, Johannes (Journal article; Peer reviewed, 2020)The North Atlantic Oscillation is the dominant atmospheric driver of North Atlantic climate variability with phases corresponding to droughts and cold spells in Europe. Here, we exploit a suggested anti-correlation of North ... -
Postglacial mass movements and depositional environments in a high-latitude fjord system – Hardangerfjorden, Western Norway
Bellwald, Benjamin; Hjelstuen, Berit Oline Blihovde; Sejrup, Hans Petter; Haflidason, Haflidi (Peer reviewed; Journal article, 2016-09)High resolution acoustic data and a 15.7 m long sediment core from the Hardangerfjorden system, western Norway, have been analyzed to increase our knowledge on depositional environments, submarine mass movement trigger ...
