Barkham knew from the documentation that in those ports there had to be remains of the Basque whaling presence, both on land and under water, and she wanted to find them. Backed by her research so far, she organized an archaeological survey expedition to southern Labrador in the summer of 1977, with a grant from the
Royal Canadian Geographical Society. She explored several harbours along the coast and discovered archaeological remains of Basque whaling bases, including at Red Bay, thereby confirming her historical work in Europe. The expedition was joined by, among others, archaeologist
James Tuck of
Memorial University of Newfoundland. They located a wreck in both harbours which turned out to be 16th-century whaling ships. The press conference announcing these finds was held at the
Public Archives of Canada. From then on, Barkham continued her historico-geographical work parallel to the land and underwater excavations, under Tuck and Grenier respectively, at Red Bay which was declared a National Historic Site of Canada in 1979. In 1982, she organized another expedition, this time by sailing boat from Cape Breton Island to southern Labrador and the Quebec North Shore. She identified 17th-century Basque cod fishing locations on the west coast of Newfoundland while, at Middle Bay and Five Leagues Harbour on the Quebec coast, she found further archaeological remains of the 16th-century Basque whaling presence. == Conferences, publications, recognition and UNESCO ==
