Sr/Ca ratios have been successfully used as a temperature proxy in corals and sclerosponges. Previous work on aragonitic bivalve shells has not been conclusive but suggests a major control of growth rate on Sr/Ca ratios. As many studies have used bivalve growth rates to determine temperature, we tested if Sr/Ca ratios could predict temperature through its relationship with growth rate. Shells from the two species of clams from the same family (veneroidea) studied here, <i>Saxidomus giganteus</i> and <i>Mercenaria mercenaria</i>, show vastly different seasonal Sr/Ca profiles. A strong relationship between average annual Sr/Ca ratios and annual growth rate was found in <i>S. giganteus</i> shells from both Washington (R<sup>2</sup> = 0.87) and Alaska (R<sup>2</sup> = 0.64), USA, but not in <i>M. mercenaria</i> shells from North Carolina, USA. Furthermore, the Sr/Ca-growth rate relationship was also evident upon a more detailed inspection of subannual growth rates in <i>S. giganteus</i> (R<sup>2</sup> = 0.73). Although there were significant positive correlations between Sr/Ca ratios and temperature in <i>S. giganteus</i> shells, the correlations were weak (0.09 < R<sup>2</sup> < 0.27), and thus Sr/Ca ratios cannot be used as a reliable temperature proxy in these species of aragonitic bivalves. It is clear from this study that Sr/Ca ratios are not under thermodynamic control in either clam species, since thermodynamics predict a negative correlation between Sr/Ca ratios and temperature in aragonite. This points toward dominance of biological processes in the regulation of Sr<sup>2+</sup>. This is also reflected by the largely differing Sr/Ca partition coefficients (D<sub>Sr</sub>) in these shells (D<sub>Sr</sub> ˜ 0.25), when compared to inorganic, coral, and sclerosponge studies (D<sub>Sr</sub> ˜ 1), all of which show a negative dependence of Sr/Ca on temperature. We suggest that caution be taken when using Sr/Ca in any biogenic aragonite as a temperature proxy when the D<sub>Sr</sub> greatly deviates from one, as this indicates the dominance of biological controls on Sr/Ca ratios.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Strong biological controls on Sr/Ca ratios in aragonitic marine bivalve shells","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"aragonite; biogenic carbonate; mollusk shell; paleotemperature proxy; strontium; oxygen isotopes; geochemistry : major and trace element geochemistry; oceanography : biological and chemical : geochemistry; oceanography : biological and chemical : stable isotopes","OtherDescriptors":null,"Notes":null,"AnaPub":2005,"MonPub":null,"DateUpdate":"2012-06-06","DateCreate":"2006-07-18","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000229774300003","VABBcode":null,"OpenAcc":0,"DOI":"10.1029/2004GC000874"},"refs":null,"anarec":{"AnaID":100935,"PubliDate":2005,"Pagination":"Q05009 (16 pp.)","XtraPublOfAnaID":null,"ISBN":null,"Volume":"6","Issue":"5","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":100768,"SerRR":"Geochemistry, Geophysics, Geosystems.
