Evaluating whale and vessel detection methods in and around the Saturna Island Interim Sanctuary Zone (ISZ) This research compares whale and marine vessel detection methods through performance metrics adapted from machine-learning models. Monitoring whale habitat use and vessel infractions in exclusion zones can inform adaptive management for whale recovery efforts. Land-based cetacean observation (LBCO) surveys and dedicated vessel surveys (DVS) were conducted during the summer of 2023 and are considered the gold standard methods for this study. Data collected for comparison from alternative detection methods include a citizen science network, thermal imaging, acoustic, radar, and automatic identification systems (AIS). The citizen science network was the most reliable method for whale detection of all species observed. Vessel detection methods demonstrated similar overall detection reliability, as radar consistently had higher recall values while AIS consistently had higher precision values. Differing scenarios where human observation is unlikely to be the gold standard are discussed and are recommended as a topic for continued research. 2024-06-05 English Young, Mikayla Joy, Ruth Joy, Ruth Chara Serna, Ana British Columbia Institute of Technology School of Construction and the Environment 2492 PDF British Columbia Institute of Technology Text This license enables reusers to copy and distribute the material in any medium or format in unadapted form only, for noncommercial purposes only, and only so long as attribution is given to the creator.
