To date, only few high-resolution observation sets are available to quantify the spatiotemporal variability of air–sea CO<sub>2</sub> fluxes. In this study, we used observations of pCO<sub>2</sub> collected daily at the ICOS station Thornton Buoy in the southern North Sea from February until December 2018 to calculate air–sea CO<sub>2</sub> fluxes. Our results show a seasonal variability of the air–sea carbon flux, with the sea being a carbon sink from February until June switching to a carbon source in July and August, before switching back to a sink until December. We calculated that the sink was largest in April (−0.95 ± 0.90 mmol C m<sup>−2</sup> d<sup>−1</sup>), while in August, the source was at its maximum (0.08 ± 0.13 mmol C m<sup>−2</sup> d<sup>−1</sup>). On an annual basis, we found a sink for atmospheric CO<sub>2</sub> of 130.19 ± 149.93 mmol C m<sup>−2</sup> y<sup>−1</sup>. Apart from region- and basin-scale estimates of the air–sea CO<sub>2</sub> flux, also local measurements are important to grasp local dynamics of the flux and its interactions with biogeochemical processes.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Air–sea carbon flux from high-temporal-resolution data of in situ CO<sub>2</sub> measurements in the southern North Sea","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-19 01:32:13.079999","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2020,"MonPub":null,"DateUpdate":"2021-09-17","DateCreate":"2021-09-16","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1,"DOI":"10.5194/bg-2020-442"},"refs":null,"anarec":{"AnaID":344944,"PubliDate":2020,"Pagination":null,"XtraPublOfAnaID":null,"ISBN":null,"Volume":"(preprint)","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":70207,"SerRR":"Biogeosciences Discussions.
