Weichselian land-sea interactions: Western Norway-Norwegian sea

Pleistocene glacial history of the NW European continental margin

“…This pattern of ice extent is also found during parts of the last deglaciation of the region . There is good evidence for the expansion of glaciers in the coastal region of western Norway during the mid and early Weichselian (Larsen and Sejrup, 1990;Larsen et al, 2000;Sejrup et al, 2000). However, little information exists from the coastal region to the north for this period.…”

“…An understanding of the number, extent and dynamics of these glacial episodes is of wide interest, considering the influence these relatively unstable parts of the ice sheets may have had upon climate, as well as their geological impact on continental margin morphology and stratigraphy. The chronology of Pleistocene glaciations has previously mainly been based on dated terrestrial sequences and records of ice-rafted detritus (IRD) in deep-sea cores (Larsen and Sejrup, 1990;Jansen and Sjøholm, 1991;Sejrup et al, 2000;Elliot et al, 2001). However, as acoustic methods, positioning techniques and methods for dating and analysing of marine cores steadily have improved, it has been possible to obtain new geological evidence for the Pleistocene glaciations from offshore areas.…”

Saalian to Weichselian stratigraphy and sedimentation along the Lågjæren - Høgjæren escarpment, southwest Norway

“…9). A composite stratigraphy from previously studied sites on J ren and Karmøy, 90 km north of the study area, gives the following three Weichselian glaciations: 1, Karmøy Stadial followed by the Bø Interstadial at 60 ka BP (Sejrup, 1987;Larsen and Sejrup, 1990); 2, J ren Stadial about 40 ka BP (Andersen et al, 1981) followed by the Sandnes Interstadial at 39-30 ka BP (Feyling-Hanssen, 1971;Andersen et al, 1987); 3, the Late Weichselian maximum glaciation, which covered J ren until ca. 13 ka BP (Andersen et al, 1987).…”

Weichselian sediments at Foss‐Eikeland, Jæren (southwest Norway): sea‐level changes and glaciation history

“…All of the interstadials are towards the upper limit of the 14 C method or older, and the chronology is still uncertain. The Bø interstadial at Karmøy is estimated to span the time interval 70-60 ka (Larsen and Sejrup, 1990), 60-45 ka (Mangerud, 1991) and 70-50 ka , and the high 14 C ages from Kalberg clay could indicate a correlation with the Bø interstadial. However, this would make the correlation with other sites on Jaeren difficult, as an interstadial with similar glaciomarine sediments has been confined to ca.…”
