AFSC/NMML/CCEP: California Current Ecosystem Program and Cascadia Research Collective: Aerial and small boat line transect data in waters of OR/WA/BC from 1989, 1990, 1991, 1996...

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.

Distance estimation experiments for vessel surveys.

Some data not collected on pinnipeds which were often too abundant to collect data from the air.

Wild value checks, internal consistency checks, duplicate record checks

Data are quality controlled by checking all entered information collected during that day. Duplicate records are removed, Data are checked for errors in formatting, consistency, and spelling.

Data not automatically processed

IT Security and Contingency Plan for the system establishes procedures and applies to the functions, operations, and resources necessary to recover and restore data as hosted in the Western Regional Support Center in Seattle, Washington, following a disruption.

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.
