Bottom water temperatures (raw and processed including confidence intervals) calculated using Mg/Ca ratios of endobenthic Uvigerina spp. from the last 50.000 years from site GeoB9508-5 off NW Africa ...
To investigate deep ocean heat uptake variability, we measured Mg/Ca ratios of Uvigerina spp. on samples from site GeoB9508-5 off NW Africa. Bottom water temperatures (BWT) were calculated using the equation cited by Roberts et al. (2016) (https://doi.org/10.1073/pnas.1511252113). To estimate the δ1...
