Description

This data accompanies Hess et al. (2024) 'The I/Ca paleo-oxygenation proxy in planktonic foraminifera: A multispecies core-top calibrations'. 

Data columns and explanation:

reference reference for the I/Ca and Mg/Ca data
site site name
sample_depth_cm sample depth (cm below sediment surface)
basin ocean basin
site_depth_km site water depth (km)
species foraminifera species
calcification_depth foraminifera calcification depth
size_fraction foraminifera size fraction
cleaning_oxidative_reductive cleaning applied to sample before trace element analysis (O = oxidative, O+R = oxidative and reductive)
local_O2_variability indication of whether the site experiences local O2 variability, rows with "yes" are excluded from Figure 4
MgCa Mg/Ca (mmol/mol)
MgCa_corr Mg/Ca corrected for effect of reductive cleaning, as necessary (mmol/mol)
