The methane (CH<sub>4</sub>) concentration in under–ice surface water before and during the storm event was 8–12&nbsp;nmol&nbsp;L<sup>−1</sup>, which resulted in a potential sea–to–air CH<sub>4</sub> flux ranging from +0.2 to +2.1&nbsp;mg CH<sub>4</sub> m<sup>−2</sup> d<sup>−1</sup> in open leads. CH<sub>4</sub> ventilation between seawater and atmosphere occurred when both open water fraction and wind speed increased. Over the nine days after the storm, sea ice grew 27&nbsp;cm thick. Initially, CH<sub>4</sub> concentrations in the sea ice brine were above the equilibrium with the atmosphere. As the ice grew thicker, most of the CH<sub>4</sub> was lost from upper layers of sea ice into the atmosphere, implying continued CH<sub>4</sub> evasion after the leads were ice–covered. This suggests that wintertime CH<sub>4</sub> emissions need to be better constrained.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Methane release from open leads and new ice following an Arctic winter storm event","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":"Methane; Arctic ocean; Sea ice; Wintertime; Storm","OtherDescriptors":null,"Notes":null,"AnaPub":2022,"MonPub":null,"DateUpdate":"2023-02-28","DateCreate":"2023-02-27","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000860965700001","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.polar.2022.100874"},"refs":null,"anarec":{"AnaID":361581,"PubliDate":2022,"Pagination":"100874","XtraPublOfAnaID":null,"ISBN":null,"Volume":"33","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":199698,"SerRR":"Polar Science.
