In this study, we applied the TEX86H on a sediment core from the Alboran Sea (western Mediterranean, core ODP-977A) covering the penultimate climate cycle, that is, from 244 to 130 ka, and compared this with previously published sea surface temperatures derived from the U-37(k)' of alkenones of haptophyta and Mg/Ca records of planktonic foraminifera. The TEX86H temperature record shows remarkably similar stadial-interstadial patterns and abrupt temperature changes to those observed with the U-37(k)' palaeothermometer. Absolute TEX86H temperature estimates are generally higher than those of U-37(k)', though this difference (<3 degrees C in 81% of the data points) is mainly within the temperature calibration error for both proxies, suggesting that crenarchaeota and haptophyta experienced similar temperature variations. During occasional events (<5% of the analyzed time span), however, the TEX86H exhibits considerably higher absolute temperature estimates than the U-37(k)'. Comparison with Mg/Ca records of planktonic foraminifera as well as other Mediterranean TEX86 and U-37(k)' records suggests that part of this divergence may be attributed to seasonal differences, that is, with TEX86H reflecting mainly the warm summer season while U-37(k)' would show annual mean. Biases in the global calibration of both proxies or specific biases in the Mediterranean are an alternative, though less likely, explanation. Despite differences between absolute TEX86H and U-37(k)' temperatures, the correlation between the two proxies (r(2) = 0.59, 95% significance) provides support for the occurrence of abrupt temperature variations in the western Mediterranean during the penultimate interglacial-to-glacial cycle.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Coherent millennial-scale patterns in U<sub>37</sub><sup>k'</sup> and TEX<sub>86</sub><sup>H</sup> temperature records during the penultimate interglacial-to-glacial cycle in the western Mediterranean","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":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2011,"MonPub":null,"DateUpdate":"2014-06-03","DateCreate":"2013-12-01","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000291320100002","VABBcode":null,"OpenAcc":1,"DOI":"10.1029/2010PA002048"},"refs":null,"anarec":{"AnaID":231302,"PubliDate":2011,"Pagination":null,"XtraPublOfAnaID":null,"ISBN":null,"Volume":"26","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":45633,"SerRR":"Paleoceanography.
