The marine mammal survey was designed for analysis using Distance sampling, and a two-team (independent observer) approach was used to correct for perception bias in resulting abundance estimates. Team 1 was stationed on the vessel's flying bridge (height above the water 13.9 m) and team 2 was located on the bridge wings (height above the water 11.2 m). Between 20 - 24 August the ship transited into the Gulf of Mexico and only team 1 was active.

Perpendicular distance to the animal is not publicly available. The dataset is accompanied by transect (effort) data which is provided as a separate file. Sightings included were detected on-effort by the flying bridge only or by both the flying bridge and bridge wing teams; you may request the full dataset and sightings including opportunistic ones directly to the provider.
