Element to Ca ratio data for various planktonic foraminifera species from different shell size fractions from surface marine sediments from box core top M35010-2 from METEOR cruise M35/1

Element to Ca ratio data for various planktonic foraminifera species from different shell size fractions from surface marine sediments from box core top M35010-2 from RV Meteor Cruise M35/1. These data were generated following full reductive cleaning and cleaning without the reductive step as detailed in Hathorne EC, Bertlich J, Hembury D and James RH (2026) The effects of shell size and mass on trace element incorporation in different species of planktonic foraminifera. Front. Mar. Sci. 13:1792234. The data were obtained using different Inductively Coupled Plasma Mass Spectrometers (ICP-MS) at different institutions. Analytical details are provided in the the above reference.
