A synthesis of worldwide measurements of the partial pressure Of CO<sub>2</sub> (pCO<sub>2</sub>) indicates that most open shelves in the temperate and high-latitude regions are under-saturated with respect to atmospheric CO<sub>2</sub> during all seasons, although the low-latitude shelves seem to be over-saturated. Most inner estuaries and near-shore coastal areas on the other hand are over-saturated with respect to atmospheric CO<sub>2</sub>. The scaling of air-sea CO<sub>2</sub> fluxes based on pCO<sub>2</sub> measurements and carbon mass-balance calculations indicate that the continental shelves absorb atmospheric CO<sub>2</sub> ranging between 0.33 and 0.36 Pg C yr<sup>-1</sup> that corresponds to an additional sink of 27% to similar to 30% of the CO<sub>2</sub> uptake by the open oceans based on the most recent pCO<sub>2</sub> climatology [Takahashi, T., Sutherland, S.C., Wanninkhof, R., Sweeney, C., Feely, R.A., Chipman, D., Hales, B., Friederich, G., Chavez, F., Watson, A., Bakker, D., Schuster, U., Metzl, N., Inoue, H.Y., Ishii, M., Midorikawa, T., Sabine, C., Hoppema, M., Olafsson, J., Amarson, T., Tilbrook, B., Johannessen, T., Olsen, A., Bellerby, R., De Baar, H., Nojiri, Y., Wong.

Deep-Sea Research 11, this issue [doi: 10.1016/j.dsr2.2008.12.009].]. Inner estuaries, salt marshes and mangroves emit up to 0.50 Pg C yr<sup>-1</sup>, although these estimates are prone to large uncertainty due to poorly constrained ecosystem surface area estimates. Nevertheless, the view of continental shelves as sinks and near-shore ecosystems as sources of atmospheric CO<sub>2</sub> allows reconciling long-lived opposing views on carbon cycling in the coastal ocean.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Reconciling opposing views on carbon cycling in the coastal ocean: Continental shelves as sinks and near-shore ecosystems as sources of atmospheric CO<sub>2</sub>","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":"Coastal ocean; Continental shelves; Estuaries; CO(2); Carbon cycle","OtherDescriptors":null,"Notes":null,"AnaPub":2009,"MonPub":null,"DateUpdate":"2012-01-11","DateCreate":"2011-12-22","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000267587200008","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.dsr2.2009.01.001"},"refs":null,"anarec":{"AnaID":210813,"PubliDate":2009,"Pagination":"578-590","XtraPublOfAnaID":null,"ISBN":null,"Volume":"56","Issue":"8-10","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":45197,"SerRR":"Deep-Sea Research, Part II.
