Jonkers, Lukas: Planktonic foraminifera d18O and Mg/Ca ratios of sediment core SK17 [dataset]. PANGAEA, https://doi.pangaea.de/10.1594/PANGAEA.965911 (dataset in review)
Abstract:
Planktonic foraminifera d18O and Mg/Ca ratios measured on Globigerinoides ruber albus from core SK17. Mg/Ca measurements were done on the 250-350 micrometer fraction and cleaning involved an oxidative step only. Seawater temperature estimates have been calculated using Mg/Ca = 0.449 exp (0.09*T) (doi:10.1029/2007PA001564). Measurements of stable oxygen isotope ratios were done on the size fraction >125 micrometer. Radiocarbon ages measures on planktonic foraminifera (Globigerinoides ruber albus) are included to reproduce and recalculate the age-depth model of the core.
