In a three-year study combining experimental and digital archaeology, Greer Jarrett has reconstructed Viking Age seafaring itineraries along the Norwegian coast, highlighting aspects of risk and opportunity, and identifying four potential harbours which may have been used during long-range sailing voyages. Greer conducted experimental voyages onboard traditional clinker boats from Åfjord, Trøndelag, covering over 5,000 km from the Arctic Circle in the north to the Danish islands in the south.
