Recent evidence pointed towards a microbial source of CDOM in the aquatic environment and led to the proposal that phytoplankton is not a direct source of CDOM, but that heterotrophic bacteria, through reprocessing of DOM of algal origin, are an important source of CDOM. In a recent experiment designed at looking at the effects of elevated pCO<sub>2</sub> on blooms of the coccolithophorid alga <i>Emiliania huxleyi</i>, we found that despite the 3 different pCO<sub>2</sub> levels tested (190, 414 and 714 ppm), no differences were observed in accumulation of CDOM over the 20 d of incubation. Unlike previous mesocosm experiments where relationships between CDOM accumulation and bacterial abundance have been observed, none was observed here. These results provide some new insights into the apparent lack of effect of pCO<sub>2</sub> on CDOM accumulation in surface waters, and question the previously proposed mechanisms and rates of CDOM production in natural phytoplankton blooms.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Chromophoric dissolved organic matter in experimental mesocosms maintained under different pCO<sub>2</sub> levels","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":"CDOM; DOC; mesocosms; viruses; cyanobacteria; heterotrophic; bacteria; CO<sub>2<; sub>","OtherDescriptors":null,"Notes":null,"AnaPub":2004,"MonPub":null,"DateUpdate":"2012-04-03","DateCreate":"2005-04-28","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000222526900002","VABBcode":null,"OpenAcc":0,"DOI":"10.3354/meps272025"},"refs":null,"anarec":{"AnaID":72775,"PubliDate":2004,"Pagination":"25-31","XtraPublOfAnaID":null,"ISBN":null,"Volume":"272","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43354,"SerRR":"Marine Ecology Progress Series.
