The high-Arctic Young Sound in north-east Greenland is characterized by a short ice-free period (July–October). The system is influenced by high run-off, mainly from glacial meltwater during summer (June–September) affecting the turbidity. Our analysis showed that Young Sound has experienced a longer period without sea ice since 1950 due to global warming and increased run-off due to melting of the land-terminating glaciers. We applied a 3D ecosystem model for Young Sound to estimate present-day primary production and potential future change (25 and 50&nbsp;years) in different scenarios of future sea ice-free periods and run-off. The light model was improved by including suspended particulate matter (SPM) released with the freshwater sources. A shorter period with sea ice coverage gave an increase of annual primary production due to a longer productive season in the model. Increased glacial run-off was found to decrease annual primary production due to more light attenuation from SPM. However, a spatial displacement of primary production was observed in the water column and between areas due to changes in light and nutrient availability. When longer ice-free periods and higher run-off were combined, primary production showed a modest increase overall except for areas with a deep productive layer suffering from stronger light limitation. The present study can contribute to a better understanding and generalization of future productivity of Greenland fjords.</span>","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Longer ice‐free conditions and increased run‐off from the ice sheet will impact primary production in Young Sound, Greenland","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-19 01:32:32.863034","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Greenland; climate change; fjord; light; primary production; sea ice cover","OtherDescriptors":null,"Notes":null,"AnaPub":2025,"MonPub":null,"DateUpdate":"2026-01-28","DateCreate":"2026-01-28","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1,"DOI":"10.1029/2024jg008468"},"refs":null,"anarec":{"AnaID":437425,"PubliDate":2025,"Pagination":"e2024JG008468","XtraPublOfAnaID":null,"ISBN":null,"Volume":"130","Issue":"5","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":272090,"SerRR":"Journal of Geophysical Research-Biogeosciences.
