We examined the individual and combined effects of increased <i>p</i>CO<sub>2</sub> (180 ppmV CO<sub>2</sub>, 380 ppmV CO<sub>2</sub> and 750 ppmV CO<sub>2</sub> corresponding to past, present and future CO<sub>2</sub> conditions, respectively) and temperature (13 °C and 18 °C) during the exponential growth phase of the coccolithophore <i>E. huxleyi</i> using batch culture experiments. We showed that cellular production rate of Particulate Organic Carbon (POC) increased from the present to the future CO<sub>2</sub> treatments at 13 °C. A significant effect of <i>p</i>CO<sub>2</sub> and of temperature on calcification was found, manifesting itself in a lower cellular production rate of Particulate Inorganic Carbon (PIC) as well as a lower PIC:POC ratio at future CO<sub>2</sub> levels and at 18 °C. Coccosphere-sized particles showed a size reduction with both increasing temperature and CO<sub>2</sub> concentration. The influence of the different treatments on coccolith morphology was studied by categorizing SEM coccolith micrographs. The number of well-formed coccoliths decreased with increasing <i>p</i>CO<sub>2</sub> while temperature did not have a significant impact on coccolith morphology. No interacting effects of <i>p</i>CO<sub>2</sub> and temperature were observed on calcite production, coccolith morphology or on coccosphere size. Finally, our results suggest that ocean acidification might have a larger adverse impact on coccolithophorid calcification than surface water warming.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Individual and interacting effects of pCO<sub>2</sub> and temperature on <i>Emiliania huxleyi</i> calcification: study of the calcite production, the coccolith morphology and the coccosphere size","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-07-02 08:58:19.190595","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2010,"MonPub":null,"DateUpdate":"2014-10-23","DateCreate":"2010-05-11","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000278184500003","VABBcode":null,"OpenAcc":1,"DOI":"10.5194/bg-7-1401-2010"},"refs":null,"anarec":{"AnaID":145397,"PubliDate":2010,"Pagination":"1401-1412","XtraPublOfAnaID":null,"ISBN":null,"Volume":"7","Issue":"5","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":68092,"SerRR":"<b>Gattuso, J.P.; Kesselmeier, J.
