Age model, raw data and interpolated raw data from proxy records of sediment cores GeoB6007-1 and GeoB6007-2
Here we present a 1200 yr long benthic foraminiferal Mg/Ca based temperature and oxygen isotope record from a ~900 m deep sediment core off northwest Africa to show that atmosphere-ocean interactions in the eastern subpolar gyre are transferred at central water depth into the eastern boundary of the...
