The archaeological excavations were carried out at the historical fishing sites; Breiðavík (BRV, 24°24'45.98”W, 65°32'38.13"N) and Kollsvík (KOV, 24°21´6.19”W, 65°36´36.07”N) in north-western Iceland (Fig 1). In July 2012 we excavated two trenches; one in Breiðavík (50cm x 50cm) and one in Kollsvík (1m x 80cm). In July 2015 we again excavated two trenches; both in Breiðavík (the first 2m x 50cm, the second 1m x 50cm).
