New study traces major glacial event in western Norway

Researchers led by Larsen have examined a well-preserved sedimentary section in western Norway to reconstruct the region's glacial history. Their analysis of raised marine deposits, dated to marine isotope stage 5c using amino acid racemization ratios from shells, points to a major glacial event around 110,000 years ago during MIS 5d. The finding refines understanding of how ice sheets in Scandinavia expanded and retreated through the last interglacial-glacial cycle.
Why now: The study offers new evidence about the timing of early glacial expansion in Norway, which is relevant to researchers tracking past climate shifts.

Evidence
- Larsen et al investigate the glacial history of western Norway from a well preserved sedimentary section. They found that there was a major glacial event in MIS 5d (~110 ka). This evidence comes from raised marine deposits dating to MIS 5c using AAR ratios from shells. There is… · DrEvanGowan@fediscience.org · 7
