C-13 labelled bicarbonate was added to nine mesocosms with a range in pCO(2) (185 to 1420 mu atm) to follow the transfer of carbon from dissolved inorganic carbon (DIC) into phytoplankton, bacterial and zooplankton consumers, and export. A nutrient-phytoplankton-zooplankton-detritus model amended with C-13 dynamics was constructed and fitted to the data to quantify uptake rates and carbon fluxes in the plankton community. The plankton community structure was characteristic for a post-bloom situation and retention food web and showed high bacterial production (similar to 31% of primary production), high abundance of mixotrophic phytoplankton, low mesozooplankton grazing (similar to 6% of primary production) and low export (similar to 7% of primary production). Zooplankton grazing and export of detritus were sensitive to CO2: grazing decreased and export increased with increasing pCO(2). Nutrient addition halfway through the experiment increased the export, but not the production rates. Although mixotrophs showed initially higher production rates with increasing CO2, the overall production of POC (particulate organic carbon) after nutrient addition decreased with increasing CO2. Interestingly, and contrary to the low nutrient situation, much more material settled down in the sediment traps at low CO2. The observed CO2 related effects potentially alter future organic carbon flows and export, with possible consequences for the efficiency of the biological pump.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"A <sup>13</sup>C labelling study on carbon fluxes in Arctic plankton communities under elevated CO<sub>2</sub> levels","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:01.897972","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2013,"MonPub":null,"DateUpdate":"2014-06-25","DateCreate":"2013-12-01","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000317010600014","VABBcode":null,"OpenAcc":1,"DOI":"10.5194/bg-10-1425-2013"},"refs":null,"anarec":{"AnaID":230923,"PubliDate":2013,"Pagination":"1425-1440","XtraPublOfAnaID":null,"ISBN":null,"Volume":"10","Issue":"3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":68092,"SerRR":"<b>Gattuso, J.P.; Kesselmeier, J.
