Extended Data Table 2 Published, unpublished and empirically derived δ18O offsets for infaunal benthic foraminiferal δ18O

From: Deeper and stronger North Atlantic Gyre during the Last Glacial Maximum

  1. *Bulimina spp. is assigned the same δ18O correction factor as Uvigerina peregrina because both species exhibit the same offset from equilibrium calcite73.
  2. †Offsets are based on new downcore benthic δ18O data from Cape Hatteras cores (see Extended Data Fig. 3).
  3. ‡Nonionellina labradorica is assigned the same δ18O correction factor as G. affinis based on the average offset between measurements from the same samples (n = 3).
