Late Weichselian and Holocene palaeoceanography of Storfjordrenna, southern Svalbard
Multiproxy analyses (including benthic and planktonic foraminifera, δ 18 O and δ 13 C records, grain-size distribution, ice-rafted debris, XRF geochemistry and magnetic susceptibility) were performed on a 14 C-dated marine sediment core from Storfjordrenna, located off of southern Svalbard. The sedi...
