The mean dissolved CH<sub>4</sub> concentration in surface waters in July 2018 (338 nmol L<sup>-1</sup>) was three times higher than in July 2016 (110 nmol L<sup>-1</sup>), and an extremely high dissolved CH<sub>4</sub> concentration in surface waters (1,607 nmol L<sup>-1</sup>) was observed at one near-shore station. The high dissolved CH<sub>4</sub> concentrations in surface waters in the BCZ in July 2018 seemed to be due to a combination of enhancement of methanogenesis and of release of CH<sub>4</sub> from gassy sediments, both most likely related to warmer conditions. The emission of CH<sub>4</sub> from the BCZ to the atmosphere was higher in 2018 compared to 2016 by 57% in July (599 versus 382 μmol m<sup>-2</sup> d<sup>-1</sup>) and by 37% at annual scale (221 versus 161 μmol m<sup>-2</sup> d<sup>-1</sup>). The European heatwave of 2018 seems to have led to a major increase of CH<sub>4</sub> concentrations in surface waters and CH<sub>4</sub> emissions to the atmosphere in the BCZ.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Response of marine methane dissolved concentrations and emissions in the Southern North Sea to the European 2018 heatwave","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-23 01:32:57.601390","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"European 2018 heatwave; Belgian coastal zone","OtherDescriptors":null,"Notes":null,"AnaPub":2019,"MonPub":null,"DateUpdate":"2023-09-04","DateCreate":"2019-11-06","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000504520600005","VABBcode":null,"OpenAcc":1,"DOI":"10.1016/j.csr.2019.104004"},"refs":null,"anarec":{"AnaID":317762,"PubliDate":2019,"Pagination":"104004","XtraPublOfAnaID":null,"ISBN":null,"Volume":"190","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42769,"SerRR":"Continental Shelf Research.
