Fig. 1

Conceptual diagram outlining the key components of the vessel strike encounter risk model. Model inputs, model parameters, and model outputs are grouped together. Colors are representative of specific model parameters (e.g., model inputs that are in green boxes are used to calculate the encounter rate). Vessel speed and vessel draft are in orange because they are used in the calculation of multiple parameters. Mortality only equals 1 when a strike is equal to 1, the probability of avoidance is equal to 0, and the probability of lethality is equal to 1.
