This downward flux is reduced by more than 70% in the mesopelagic zone (100 to 1000 meters of depth), but this loss cannot be fully accounted for by current measurements. For decades, it has been hypothesized that the missing loss could be explained by the fragmentation of large aggregates into small particles, although data to test this hypothesis have been lacking. In this work, using robotic observations, we quantified total mesopelagic fragmentation during 34 high-flux events across multiple ocean regions and found that fragmentation accounted for 49 ± 22% of the observed flux loss. Therefore, fragmentation may be the primary process controlling the sequestration of sinking organic carbon.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Major role of particle fragmentation in regulating biological sequestration of CO<sub>2</sub> by the oceans","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-05-15 01:33:07.056403","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2020,"MonPub":null,"DateUpdate":"2021-03-25","DateCreate":"2020-02-14","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000514105000035","VABBcode":null,"OpenAcc":0,"DOI":"10.1126/science.aay1790"},"refs":null,"anarec":{"AnaID":321635,"PubliDate":2020,"Pagination":"791-793","XtraPublOfAnaID":null,"ISBN":null,"Volume":"367","Issue":"6479","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43776,"SerRR":"Science (Washington).
