Abstract
Deglacial patterns and ice-sheet dynamics in the fjords of southern Nordland, Norway
Highlights
Ice-marginal features deposited during the Younger Dryas (YD) chronozone – 12.7–11.5 cal ka BP (Lohne et al, 2013) – are traceable around a large part of the former Scandinavian Ice Sheet (Andersen et al, 1995; Mangerud et al, 2011)
The deposits mapped by Bargel (2003) are morpho-stratigraphically correlated with moraines deposited during the Tautra glacial event in the Trondheimsfjorden–Fosen peninsula region (Fig. 1), where a number of radiocarbon dates suggest that the moraines were deposited early in the YD (Reite, 1994; Olsen et al, 2015)
Few absolute dates related to the deglacial phase exist for the southern Nordland region, and the overall deglaciation chronology in this sector of the Scandinavian Ice Sheet is poorly constrained (Hughes et al, 2016)
Summary
Ice-marginal features deposited during the Younger Dryas (YD) chronozone – 12.7–11.5 cal ka BP (Lohne et al, 2013) – are traceable around a large part of the former Scandinavian Ice Sheet (Andersen et al, 1995; Mangerud et al, 2011). Bargel (2003) mapped end moraines and ice-marginal features in the outer Tosenfjord region (Fig. 2) just south of our study area, adding observations and radiocarbon chronology to previous work done by Svensson (1959). Few absolute dates related to the deglacial phase exist for the southern Nordland region, and the overall deglaciation chronology in this sector of the Scandinavian Ice Sheet is poorly constrained (Hughes et al, 2016)
