DATA & FILE OVERVIEW

1. Description of dataset

These data were used to scale 3D models of humpback whales constructed in Blender, an open source modeling software.
	a. New York Bight: Morphometric measurements of humpback whales were collected in the New York Bight using a DJI Phantom Pro+ (V1.0) Unoccupied Aerial Vehicle (UAV). UAV flights and detailed methods for obtaining morphometric measurements in cm are described in Stepanuk et al. (2021). We obtained measurements of total body length (TL) and body widths at 5% intervals along the body axis of the whale (Fig. 1A) using the open-source platform MorphoMetriX (Torres & Bierlich 2020) and summarized the output data for all individuals into a single output file using CollatriX (Bird & Bierlich 2020). 
	b. Australia: Field studies of humpback whales in Australia described in Christiansen et al. (2020) and subsequent sampling efforts provided dorsal and lateral images and TL, height, and width measurements at 5% intervals of TL. These data were used to produce mean height to width (HW) ratios at 5% intervals of TL.

DATA-SPECIFIC INFORMATION FOR: 0215_morphs_58-whales.csv

1. Number of variables: 23

2. Number of cases/rows: 58

3. Variable List:
	Animal_ID: Animal identification number; format TLXXXX
	rep_class: Reproductive class of the individual, assigned where animals < 12 m are juveniles and animals >=12 m are adults
	Image: Image ID entered into MorphometriX to generate measurements in meters
	WL: Total length of the animal; meters
	5-95: Width measurements as output by MorphometriX; the column number corresponds to the percentage along the body from the rostrum to the fluke notch



4. Missing data codes:
	None

5. Abbreviations used:
	None



DATA-SPECIFIC INFORMATION FOR: Dorso.lateral.data.2017.2020.2021.txt

1. Number of variables: 41

2. Number of cases/rows: 32

3. Variable List:
	Frame.name: Image ID used in the measuring process
	Rep.class: Reproductive class assigned based on relative size (e.g., calves were identified as being much smaller than their mothers) and total length. See Christiansen et al. (2020) for details.
	Location: Sampling location for the individual; "WA" for Western Australia or "NSW" for New South Wales
	Width.5.proc.rel - Width.95.proc.rel: Width measurements of the individual as a proportion of the total length of the animal, where for column Width.XX.proc.rel, XX is the the percentage along the body from the rostrum to the fluke notch
	Height.5.proc.rel - Height.95.proc.rel: Height measurements of the individual as a proportion of the total length of the animal, where for column Height.XX.proc.rel, XX is the the percentage along the body from the rostrum to the fluke notch



4. Missing data codes:
	None

5. Abbreviations used:
	None
