Age determination of Northwest Atlantic sediment cores

This dataset contains new and updated age models for sediment cores from depth transects at Blake Outer Ridge and Cape Hatteras. Primarily, this includes new AMS-14C ages measured on planktic and/or benthic foraminifera, as well as δ18O (and other) tie points. We also include previously published 14C that has been recalibrated using new reservoir ages and updated calibration curves (Marine 20; ∆R=-128±68; Heaton et al., 2020). AMS-14C measurements were made at the NERC NEIF Radiocarbon Laboratory (University of East Kilbride, Scotland, UK), KCCAMS Radiocarbon Facility (University of California, Irvine, CA, USA), and NOSAMS Facility (Woods Hole Oceanographic Institution, MA, USA), following standard procedures.
