The highest number of flares occurs on the shelf, and the highest flare density is seen around the nutrition-rich outflow of the Juan de Fuca Strait. We determine ∼430 flow-rates at ∼340 individual flare locations along the margin with instantaneous in situ values ranging from ~6 mL min<sup>−1</sup> to ∼18 L min<sup>−1</sup>. Applying a tidal-modulation model, a depth-dependent methane density, and extrapolating these results across the margin using two normalization techniques yields a combined average in situ flow-rate of ∼88 × 10<sup>6</sup> kg y<sup>−1</sup>. The average methane flux-rate for the Cascadia margin is thus estimated to ∼0.9 g y<sup>−1</sup>m<sup>−2</sup>. Combined uncertainties result in a range of these values between 4.5 and 1800% of the estimated mean values.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Distributed natural gas venting offshore along the Cascadia margin","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-05-25 01:31:41.494579","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2018,"MonPub":null,"DateUpdate":"2018-09-26","DateCreate":"2018-09-26","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000441608900004","VABBcode":null,"OpenAcc":1,"DOI":"10.1038/s41467-018-05736-x"},"refs":null,"anarec":{"AnaID":301603,"PubliDate":2018,"Pagination":"14 pp","XtraPublOfAnaID":null,"ISBN":null,"Volume":"9","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":198717,"SerRR":"Nature Communications.
