Abstract:
Radiocarbon was measured on mono-specific samples of between 30 and 350 individual foraminiferal tests taken from five different sediment cores. Single samples were taken at each depth with the aim of developing a down-core age-depth model.
For cores GeoB10058-1, GeoB10054-4, GeoB10066-7 and OR1-1218-C2-BC, radiocarbon dating was performed by Accelerated Mass Spectrometry (AMS) using a Mini Carbon Dating System (MICADAS) (Wacker et al. 2010) at the Alfred Wegener Institute, Bremerhaven, Germany, and following standard operating procedures. Samples were measured using a graphite target, except for the single sample from OR1-1218-C2-BC with only 30 specimens, for which a gas target was used. Blanks were processed and correction performed according to a procedure in Sun et al. (2020).
Radiocarbon dating of the bulk samples from core SO213-84-2 was carried out on the 15th of May 2014, at NOSAMS, Woods Hole Oceanographic Institution and Keck Carbon Cycle AMS Laboratory, University of California, Irvine.
