Between 2014 and 2021, a total of 18 white sharks received accelerometer packages. These sharks were outfitted at the Neptune Islands and Liguanea Island . Then, came the prediction models. “A random forest model was built to assign behaviours based on known behavior profiles. These profiles are built using movement data from known behaviours across several sharks. The model can then use these profiles to assign behaviours to movement data for which animal-borne camera data is unavailable.
