The data reflect 25 hours of observer effort (on transect), and 62 sightings of four identifiable species, including killer whales (Orcinus orca), sperm whales (Physeter macrocephalus), long-finned pilot whales (Globicephala melas), and bottlenose dolphins (Tursiops sp.). Numerous unidentified cetaceans and sharks were also seen.

The aircraft travelled at an altitude of 1,000 feet and a speed of 120 knots, as per widely established cetacean survey methods. Pre-determined transects were flown in passing mode (no deviation from the track line), with 'circle-backs' only permitted following encounters with killer whales (Orcinus orca; the target species). The combination of two different survey designs (A: large-scale zigzags, B: fine-scale parallel sweeps) allowed appropriate coverage of the region as a whole (i.e. park and surroundings) whilst maximising data gathering opportunities at a known killer whale aggregation site west of the area. Sightings were logged on Olympus digital recorders via headset by two trained observers each scanning either side of the aircraft. Clinometers (Suunto PM-5/360PC) and compass boards were used to record vertical and horizontal angles for each wildlife detection.
