The National Marine Mammal Laboratory (NMML) a division of NOAA's Alaska Fisheries Science Center (Seattle, WA) and Cascadia Research Collective (Olympia, WA) conducted aerial and small boat line transects to estimate the abundance of harbor porpoises in waters of Oregon, Washington, and British Columbia, Canada. This dataset contains line transect survey data with effort (line length) and sighting data (species, group size, distance/angle) and associated covariate data. This dataset provides information used to estimate harbor porpoise abundance in Oregon, Washington, and British Columbia, Canada waters.

Completeness Report Some data not collected on pinnipeds which were often too abundant to collect data from the air. Conceptual Consistency Wild value checks, internal consistency checks, duplicate record checks Aerial line transect from Partenavia with 2 side window observers and a belly window observer. Inclinometer used to measure angle and with altitude used to get perpendicular distance. For vessel surveys, radial distance estimated visually and angle board used for horizontal angle.
