Photogrammetric measurements of humpback whales to estimate total body length and body condition.
body_condition_measurements
A data frame with 29 rows and 28 columns:
unique ID for the individual whale
total body length measurement (m)
Width of whale (m), pre-computed from pixels using the reported laser altimeter measurement. Width is taken at a cross-section perpendicular to the whale's center line, running from the middle of the rostrum (loosely, the whale's beak/nose) to the middle of the peduncle (the point where the tail connects to the rest of the body). The cross-section is taken 10 from the animal's rostrum to its peduncle.
