Here, we assess the vulnerability of the North Water polynya, a unique seaice ecosystem that sustains the world's northernmost Inuit communities and several keystone Arctic species. We reconstruct mid-to-late Holocene changes in sea ice, marine primary production, and little auk colony dynamics through multi-proxy analysis of marine and lake sediment cores. Our results suggest a productive ecosystem by 4400-4200 cal yrs b2k coincident with the arrival of the first humans in Greenland. Climate forcing during the late Holocene, leading to periods of polynya instability and marine productivity decline, is strikingly coeval with the human abandonment of Greenland from c. 2200-1200 cal yrs b2k. Our long-term perspective highlights the future decline of the North Water ecosystem, due to climate warming and changing sea-ice conditions, as an important climate change risk.</dcterms:abstract> <dc:rights>Attribution 4.0 International</dc:rights> <dc:contributor>Larsen, Nicolaj K.</dc:contributor> <dspace:isPartOfCollection rdf:resource=""/> <dc:creator>Grønnow, Bjarne</dc:creator> <foaf:homepage rdf:resource="http://localhost:8080/jspui"/> <dc:contributor>Giraudeau, Jacques</dc:contributor> <dc:contributor>Wengrat Ribeiro, Simone</dc:contributor> <dcterms:hasPart rdf:resource=""/> <dspace:hasBitstream rdf:resource=""/> <dcterms:isPartOf rdf:resource=""/> <dc:creator>Larsen, Nicolaj K.</dc:creator> <dc:contributor>Nuttall, Mark</dc:contributor> <dc:contributor>Mosbech, Anders</dc:contributor> <dc:creator>Ribeiro, Sofia</dc:creator> <dc:creator>Wengrat Ribeiro, Simone</dc:creator> <dc:creator>Nuttall, Mark</dc:creator> <dcterms:rights rdf:resource=""/> <dc:creator>Giraudeau, Jacques</dc:creator> <dcterms:issued>2021</dcterms:issued> <dcterms:title>Vulnerability of the North Water ecosystem to climate change</dcterms:title> <dc:contributor>Grønnow, Bjarne</dc:contributor> <dc:contributor>Davidson, Thomas A.</dc:contributor> </rdf:Description> </rdf:RDF>
