Very large data set used to calibrate carbon isotope composition deep-sea benthic foraminifera

Editor’s Highlight—


Over the years, many paleoceanographic proxy data have been collected on deep-sea benthic foraminifera, with carbon isotope data on foraminiferal tests used widely to reconstruct deep ocean circulation and ocean productivity. This paper compiles a very large data set (>1700 data points) to calibrate the δ13C proxy, look into errors, and evaluates regional differences, effects of pressure and carbonate saturation, as well as effects of anthropogenic fossil fuel burning.
