The first undisputed presence of Basque whaling expeditions in the New World was in the second quarter of the 16th century. It appears to have been the French Basques, following the lead of Breton cod-fishermen that reported finding rich whaling grounds in Terranova (Newfoundland). The Basques called the area they frequented Grandbaya (Grand Bay), today known as the Strait of Belle Isle, which separates Newfoundland from southern Labrador. Their initial voyages to this area were mixed cod and whaling ventures. Instead of returning home with whale oil, they brought back whale meat in brine. The French Basque ship La Catherine d'Urtubie made the first known voyage involving whale products in 1530, when she supposedly returned with 4,500 dried and cured cod, as well as twelve barrels of whale meat "without flippers or tail" (a phrase for whale meat in brine). After a period of development, expeditions were sent purely aimed at obtaining whale oil. The first establishments for processing whale oil in southern Labrador may have been built in the late 1530s, although it wasn't until 1548 that notarial documents confirm this.
