"General taxonomic coverage description: All waterbirds (and mammals) were identified to their lowest taxonomic classification. Observations that could not distiguish between Murres and Razorbills were classified as "Uria or Alca" in the ECSAS collection. Observations that could not distiguish between Arctic or Common Tern were classified as "Sterna hirundo or Sterna paradisaea". Landbirds are not included." "Study extent description: Survey data were collected primarly in coastal and offshore waters of Eastern Canada, including the Gulf of St. Lawrence and western North Atlantic. Survey data were also collected in the eastern North Pacific, Arctic, and in international waters beyond Canada's Exclusive Economic Zone. We conduct surveys from ships and stationary platforms, targeting areas where data are lacking or are of interest for conservation and management purposes.” Sampling description: We record birds observed along a line transect, typically 300m in width, scanning a 90° arc to one side of the ship, and use the snapshot approach for flying birds (intermittent sampling based on the speed of the ship). Distance sampling methods are incorporated to address the variation in bird detectability. Marine mammals observations are also included, although surveys were not specifically designed to detect marine mammals."
