Both sources are generally considered separately, yet their effects on the biological carbon pump could interact. Using a global ocean-sea-ice-biogeochemical model with a representation of both continental and sea ice iron sources, we find them to have an overall additive effect on phytoplankton activity, increasing carbon export by +13.9% of the Southern Ocean total, with continental ice contributing +4.5% and sea ice +8.0%. The +1.4% residual is due to a coupled fertilization effect: When the iron source from continental ice is activated, iron in sea ice increases by 16%, so does iron transport toward low production areas. Overall, this increases phytoplankton activity: Fertilization is more efficient where sea ice melts than at locations of initial iron release by continental ice.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Continental and sea ice iron sources fertilize the Southern Ocean in synergy","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-10 01:32:48.401537","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"iron; cryosphere; Southern Ocean; fertilization; biological carbon pump; modeling","OtherDescriptors":null,"Notes":null,"AnaPub":2021,"MonPub":null,"DateUpdate":"2023-03-20","DateCreate":"2023-03-17","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000730019700010","VABBcode":null,"OpenAcc":1,"DOI":"10.1029/2021GL094761"},"refs":null,"anarec":{"AnaID":362273,"PubliDate":2021,"Pagination":"e2021GL094761","XtraPublOfAnaID":null,"ISBN":null,"Volume":"48","Issue":"23","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42920,"SerRR":"Geophysical Research Letters.
