Concentrations of boron, lithium, strontium, and sulfur have been shown to vary with carbonate system parameters, but when comparing individual proxy reconstructions based on these elements, they are rarely in complete agreement. This is likely caused by the simultaneous effects of multiple environmental factors on element incorporation. Culture experiments with benthic foraminifera have revealed that the shell's S/Ca reflects the carbon chemistry and can potentially be used as a proxy for seawater [</span>CO32−<span style=\"background-color:rgb(255,255,255);color:rgb(0,0,0);\">]. Aiming to investigate the application potential of sulfur incorporation for carbonate speciation reconstruction, we present S/Ca ratios in five planktonic foraminiferal species, namely </span><i>Globigerina bulloides</i><span style=\"background-color:rgb(255,255,255);color:rgb(0,0,0);\">, </span><i>Globigerinoides ruber albus</i><span style=\"background-color:rgb(255,255,255);color:rgb(0,0,0);\">, </span><i>Globigerinoides ruber ruber</i><span style=\"background-color:rgb(255,255,255);color:rgb(0,0,0);\">, </span><i>Trilobatus sacculifer</i><span style=\"background-color:rgb(255,255,255);color:rgb(0,0,0);\">, and </span><i>Neogloboquadrina incompta</i><span style=\"background-color:rgb(255,255,255);color:rgb(0,0,0);\"> from core-top sediments in regions with contrasting [</span>CO32−<span style=\"background-color:rgb(255,255,255);color:rgb(0,0,0);\">], [</span>HCO3−<span style=\"background-color:rgb(255,255,255);color:rgb(0,0,0);\">], temperature, and salinity. Analyses of B/Ca and Mg/Ca ratios are included here since these elements have been shown to depend to a certain degree on carbon system parameters (e.g., calcite saturation state and pH, respectively) as well. Moreover, foraminiferal Mg/Ca values covary with S/Ca values and thereby might compromise its proxy application. In contrast to previously published results, this new data set shows a positive correlation between the incorporation of sulfur in the foraminifer's shell and seawater [</span>CO32−<span style=\"background-color:rgb(255,255,255);color:rgb(0,0,0);\">]. As the incorporation of sulfur and magnesium are positively correlated, S/Mg values of the same foraminifera may be used to improve inorganic carbon system reconstructions.</span>","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Impact of seawater inorganic carbon chemistry on element incorporation in foraminiferal shell carbonate","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-08 01:31:36.520324","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"planktonic foraminifera; element incorporation; proxy; inorganic carbon chemistry; core-top sediment","OtherDescriptors":null,"Notes":null,"AnaPub":2024,"MonPub":null,"DateUpdate":"2024-07-16","DateCreate":"2024-07-16","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1,"DOI":"10.1029/2023gc011302"},"refs":null,"anarec":{"AnaID":393338,"PubliDate":2024,"Pagination":"e2023GC011302","XtraPublOfAnaID":null,"ISBN":null,"Volume":"25","Issue":"4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":100768,"SerRR":"Geochemistry, Geophysics, Geosystems.
