  • 1. Economic of Extinction in Greenland –Zooarchaeology of Vatnahverfi Region in Norse Eastern Settlement Konrad Śmiarowski PhD Program The Graduate Center CUNY 365 Fifth Avenue, New York, NY 10016-4309 zaglobax@yahoo.com
  • 2. Norse Settlements •Greenland was settled from Iceland ca. 985 AD •Two areas of permanent farms in the SW. •Eastern Settlement has ca. 400 ruin groups. •Western Settlement has ca. 80 ruin groups. Norðursetur •The Norðursetur (Northern Hunting Grounds) were in the Disko Bay area, 800 km N of the settlements. •Western Settlement becomes extinctWestern ca 1350 (switch from “Norse” settledSettlement cultural landscape to “Inuit” mobile landscape) •Eastern Settlement lasts at least Eastern another 100 years Settlement

  • 4. Midden Excavation at E172 Tatsip Ataa -2007, 2009, 2010• 3 Seasons of midden excavation – over 50m2 in main area + 2 small trenches• Long period of occupation 1000AD to 14th C.• Large archaeofauna under analysis at CUNY• Dry and wet sieving in 4mm mesh for optimal artifact and bone recovery – 100% Bone and artifact collection• Palaeobotany and Entomology sampled • Detailed Survey work, including GPR and geomagnetics • Column sample taken in a peat bog next to the dwelling • The only known site with organic preservation at the time of the excavations – Global warming severely affected waterlogged, frozen deposits in ALL of SW Greenland

  • 6. Seal Biology in Greenland Hooded Harp• Migratory Harp (P.groenlndica) and Hooded (C. crystata) seals ride the spring and summer sea ice. Number in millions.• Arctic non-migratory seals present all winter (breathing hole). Ringed (P.hispida- Nerpa) and Bearded (E. barbatus) seals.• Harbor/Common seals (P. vitulina) are driven off by heavy summer sea ice, if occurs Map: Aqqalu Rosing-Asvid
  • 7. Harbor/Common Seals•Form small concentrations at hauling out spots on sandybeaches•Vulnerable to human hunters when have pups on shore•Over-hunting, and local population extinctions or dispersal arepossible•Can not reproduce in ice filled waters

  • 10. Why Low Common Seal Numbers in the Later Phases ?• Depletion of common seal stocks in the area due to over-hunting by Norse hunters? (they survive for 300 years)• Climatic change from earlier, warmer conditions with little or no summer drift ice to a climate similar to modern conditions during the later 13th century AD ?

  • 13. • Summer drift ice affects harbor (common) seal colonies• Drift ice also cools sea level pastures, reducing growing season of the most productive plant communities and pastures• Causes intensification of migratory seal hunting after 1250-1300 AD

  • 17. • Harbor seal colonies managed successfully in both Norse settlements• Resilient Norse successfully intensify migratory seal hunting as a response to century long unpredictable, unfavorable temperature change post 1250- 1300 AD• 15th Century Conjunctures that contributed to Norse Demise High magnitude cold temperature hazards overlap with high magnitude unpredictable storminess (affecting agricultural activity & trade with Europe) Political and economic changes in Europe result in decreased contact and Ivory demand and export Cultural contact with Thule Inuit – hostile? Resource competition?
