Advancing planktonic foraminifera Mg/Ca thermometry: a microanalytical perspective
Microanalytical techniques, specifically laser ablation - inductively coupled plasma mass spectrometry (LA-ICPMS) and electron microprobe analysis(EMPA), have been used to determine Mg/Ca compositional variation within and between tests of planktonic foraminifera. Micro-scale characterization of thi...
