Metadata Updated: November 1, 2024

Gray whale (Eschrichtius robustus) survey and sightings data from 1993 - 2014 collected by the Marine Mammal Laboratories' California Current Ecosystem Program (AFSC/NOAA) personnel.

Lineage Surveys are conducted in the study area. The number of gray whales per nautical mile are recorded. Photographs (using a high-resolution camera) are taken of the left, right, and under (ventral) side of the fluke of each whale seen. These photos are compared with those from a master database (Cascadia Research Collective, Olympia, Washington) to determine each animal's identification. Photos are sent to Cascadia Research Collective and they send back the best photograph of the left, right, and ventral side of the individual. This dataset includes survey data and identifications of sighted whales but not photographs from the surveys.
