Abstract:

We present biomarker, foraminiferal abundance, stable isotope and trace element data from sediment cores JM11-FI-19PC and LINK16 from the southern Norwegian Sea during 130-110 ka. Sediment core JM11-FI-19PC was retrieved from a water depth of 1179 m northwest of the Faroe Islands (62°49′N, 03°52′W). Sediment core LINK 16 was retrieved from a water depth of 773 from the northeast of the Faeroe–Shetland Channel (62°36′N, 3°31′W). For sediment core LINK16, brassicasterol (24-methylcholesta-5, 22E-dien-3β-ol), IP25 (a C25 Isoprenoid Lipid), benthic foraminiferal assembalges, and foraminiferal stable isotope data are provided. For sediment core JM-FI-19PC, brassicasterol , IP25 and foraminiferal Na/Ca and Ba/Ca are provided. The age models of both sediment cores M11-FI-19PC and LINK 16 are provided.
