Stable oxygen and carbon isotopes of benthic foraminifera from IODP Site U1534
Dataset is comprised of stable isotopes (oxygen and carbon) of benthic foraminifera from sediments from International Ocean Discovery Program (IODP) Expedition 382, Site U1534, South Falkland Sediment Drift. 53.18967 S, 58.76083 W (605 m water depth).
The sediment cores were collected from 3 holes using the advanced piston corer onboard RV Joides Resolution from site U1534 between 29/03/2019 and 02/04/2019. Suitable specimens of benthic foraminifera were identified and picked from the >250 micron size fraction sediment at BAS between March 2020 and May 2021. Isotope analysis was carried out between March-August 2021.
The data were collected as part of a project aiming to investigate the sensitivity of the Atlantic Meridional Overturning Circulation to variability in Pacific-Atlantic connectivity via the 'cold water route'. Dr Victoria Louise Peck was the principle investigator for this project.
Funding provided by NERC UKIODP moratorium grant NE/T010908/1 and analytical support from NEIF steering committee application IP-1950-119.

Methodology:
Wherever present, specimens of Uvigerina bifurcata were picked from samples at 10 cm intervals. During warmer periods when U. bifurcata was not present, Melonis affinis and/or Hoeglundina elegans were analysed. The number of specimens per analysis is indicated, typically 4.
Depth is composite core depth (below sea floor) based on splicing of ship-board physical properties from 3 adjacent holes within 20 m of each other. Splice information is available here LIMS Online Report Portal (tamu.edu)
Isotopic analysis was performed on the GV IsoPrime mass spectrometer at NERC National Environmental Isotope Facility, BGS, Keyworth. Isotopic ratios are calibrated to the Vienna-PDB standard and 1-sigma standard deviation for delta13C and delta18O is 0.03 and 0.05 per mil respectively.
