M., Tackaberry J., Hayslip C., Flynn K., New L., Baker C. S., Steel D., Martien K. K., Moore J. E., Lauf M., Wickman L., Wall A., Newell C., Torres L. G. (2025) Rates of entanglement inferred from scarring prevalence of humpback whales photographed in US Oregon waters, Endangered Species ResearchThese photos are the property of the laboratory that have collected and curated them. For questions relative to these photos datasets, please contact:WHET Lab contact: Craig Hayslip ([e-mail])GEMM Lab contact: Leigh G. Torres ([e-mail])CRC contact: Jenn Tackaberry ([e-mail] ) or John Calambokidis ([e-mail])Keywords are added to the photo metadata to code for various variables used in the study. Keywords useful for the analysis are listed and described below. All other keywords found in the photo metadata can be ignored.Keywords coding for photo sourceSource-CRC (photos contributed by Cascadia Research Collective), Source-GEMMLab (photos contributed by the GEMM Lab -Oregon State University- and their field partners), Source-WHETLab (photos contributed by the WHET Lab – Oregon State University)Keywords coding for photo qualityFrom best to lowest quality: QUA1, QUA2, QUA3, QUA4Keywords coding for photo typeDorsal tailstock, Fluke underside, Forward tailstock, Perpendicular tailstock, Ventral tailstockKeywords coding for Wall et al. (2019) categories of entanglement likelihoodFrom least to most likely: ENT4-Unlikely, ENT3-Possibly, ENT2-Likely, ENT1-Most likelyKeywords coding for Robbins & Mattila (2001) scar codes per regionPerp-code-LFlank = left flank scar codeFrom least to most likely: LFlank-S0, LFlank-S1, LFlank-S2, LFlank-S3, LFlank-S4, LFlank-S5Perp-code-RFlank = right flank scar scodeFrom least to most likely: RFlank-S0, RFlank-S1, RFlank-S2, RFlank-S3, RFlank-S4, RFlank-S5Perp-code-LFluke = left fluke trailing edge scar codeFrom least to most likely: LFluke-S0, LFluke-S1, LFluke-S2, LFluke-S3, LFluke-S4, LFluke-S5Perp-code-RFluke = right fluke trailing edge scar codeFrom least to most likely: RFluke-S0, RFluke-S1, RFluke-S2, RFluke-S3, RFluke-S4, RFluke-S5Perp-code-VP = ventral tailstock scar codeFrom least to most likely: VP-S0, VP-S1, VP-S2, VP-S3, VP-S4, VP-S5Perp-code-DP = dorsal tailstock scar codeFrom least to most likely: DP-S0, DP-S1, DP-S2, DP-S3, DP-S4, DP-S5Keywords coding for individual IDAll keywords starting with “CRC”… (eg., CRC13626, CRC11523 etc.) are unique codes given to individual whales. For most photos, these IDs are incorporated directly as keywords. For those that do not have such code, refer to the score_df dataset provided as supplementary material (https://github.com/SoleneDerville/HW_scarring_analysis) to find the unique code of individuals found in each photo.Other keywords of interest4-Fresh = keyword present if photo shows fresh / raw injuries6-Strike = keyword present if scars indicative of a potential ship strike are found on photo7-Mirrored_fluke_notches = keyword present if opposite cuts or deep indentation are found on the trailing edge of the fluke (criteria not used in the present study)8-Fluke-entirely visible = keyword present for fluke underside photos if the fluke is entirely above waterNB: Although this dataset is licensed under CC BY 4.0 due to Figshare limitations, the authors explicitly prohibit any commercial use.
