| Summary: | Progress Code: completed Purpose Individual identification allows the production of sightings histories required for a mark-recapture approach to estimating abundance. These data will also provide information on blue whale population structure and movement. Individual blue whales are identifiable from unique patterns of mottled pigment on both sides of the body, and also from variations in dorsal fin shape and any permanent scars that may be present. All photos taken during the Antarctic blue whale voyage in an attempt to get a best photo identification image of Antarctic blue whales, pygmy blue whales, killer whales, right whales and humpback whales. Image collection location and other details such as photographer, species, date (UTC) can be found in excel spreadsheet.
