We find that rises in surface water DIC and <em>p</em>CO<sub>2</sub> exceeded concurrent rises in atmospheric <em>p</em>CO<sub>2</sub>, which we attribute primarily to biological activity in late summer. After accounting for this biological signal, the observed ocean acidification occurs at a rate that is consistent with concurrent atmospheric and open ocean CO<sub>2</sub> increases over the 2001-2011 decade. Nevertheless, we do find a consistent reduction in CO<sub>2</sub> undersaturation in the NNS and an increase in CO<sub>2</sub> supersaturation in the SNS. We propose that the synergistic effects of increasing atmospheric <em>p</em>CO<sub>2</sub> and subsequent decrease in seawater buffering capacity, together with rising sea surface temperatures in the future oceans, may reduce the strength of the North Sea as a CO<sub>2</sub> sink. Such a reduction would diminish the efficiency of this region as a continental shelf pump with respect to uptake of CO<sub>2</sub> by the sea. Ultimately this would constitute a positive feedback mechanism, i.e. enhancing the airborne fraction of anthropogenic CO<sub>2</sub> and thus the net rate of increase of atmospheric <em>p</em>CO<sub>2</sub> and subsequent global climate change.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Rapid increase of observed DIC and pCO<sub>2</sub> in the surface waters of the North Sea in the 2001-2011 decade ascribed to climate change superimposed by biological processes","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-22 01:32:22.028377","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Air-sea CO2 exchange, Mechanisms of Ocean Acidification","OtherDescriptors":null,"Notes":null,"AnaPub":2015,"MonPub":null,"DateUpdate":"2021-10-19","DateCreate":"2021-10-19","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000366788600016","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.marchem.2015.08.010"},"refs":null,"anarec":{"AnaID":345848,"PubliDate":2015,"Pagination":"566-581","XtraPublOfAnaID":null,"ISBN":null,"Volume":"177","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43353,"SerRR":"Marine Chemistry.
