Here, we present a new Mg/Ca-Δ<SUB>47</SUB> dataset for modern planktonic foraminifera, from various oceanographic basins and covering a large range of temperatures (from 0.2 to 25.4 °C). These measurements were performed on the same samples and species as the ones used for the foraminiferal Δ<SUB>47</SUB> calibration of Peral et al. (2018), allowing comparison between both Mg/Ca and Δ<SUB>47</SUB> paleothermometers (excluding the two benthic foraminiferal data points). There is a good agreement between these two paleothermometers when the Mg/Ca-temperature is corrected for seawater salinity and pH, suggesting that foraminiferal Δ<SUB>47</SUB> may not be influenced by salinity or pH. However, our results show that Δ<SUB>47</SUB> temperature uncertainties still limit our ability to reconstruct pH and δ<sup>18</sup>O<sub>sw</sub> from the combination of Mg/Ca, δ<sup>18</sup>O and Δ<SUB>47</SUB> in a useful manner. We also find that disagreements between Mg/Ca and Δ<SUB>47</SUB> values in <i>G. bulloides</i> persist after correction for vital, salinity and pH effects, suggesting that other process(es) may also influence Mg/Ca in this species.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"On the combination of the planktonic foraminiferal Mg/Ca, clumped (Δ<sub>47</sub>) and conventional (δ<sup>18</sup>O) stable isotope paleothermometers in palaeoceanographic studies","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-18 01:32:32.600712","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2022,"MonPub":null,"DateUpdate":"2023-02-27","DateCreate":"2023-02-27","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000887436800003","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.gca.2022.10.030"},"refs":null,"anarec":{"AnaID":361502,"PubliDate":2022,"Pagination":"22-34","XtraPublOfAnaID":null,"ISBN":null,"Volume":"339","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42901,"SerRR":"Geochimica et Cosmochimica Acta.
