Benthic foraminiferal oxygen isotope data (δ18O) and age models from Northwest Atlantic sediment cores forming depth transects at Blake Outer Ridge and Cape Hatteras

DOI

This dataset is used to reconstruct the hydrography of the Northwest Atlantic during the Mid-Holocene (2-6 ka BP) and Last Glacial Maximum (19-23 ka BP). It consists of: (1) vertical δ18O profiles derived from multi-species benthic foraminiferal δ18O measurements from sediment cores in two depth transects at Cape Hatteras (~36-39°N) and Blake Outer Ridge (~30-33°N), (2) the monospecific benthic foraminiferal δ18O measurements that underpin these profiles, (3) age constraints, including new radiocarbon dates, used to determine the relative positions of the Mid-Holocene and Last Glacial Maximum in each of the sediments cores in each transect, and (4) multi-species downcore benthic δ18O measurements from four of the sediment cores in the Cape Hatteras transect.
