Bottlenose dolphin abundance CA coastal stock: Estimates from mark-resighting analysis; see Dudzik 1999, Weller et al. 2016. Abundance is calculated from closed population models and averaged over 2 or 3 year intervals. X-axis last year used for each period. Abundance of short-beaked common dolphin, Dall's porpoise, Fin whale, Blue whale, Humpback whale: Estimates from ship-based line transect surveys; see Barlow 2016. Gray whale abundance: Estimates from shore-based counts using baysian model; see Durban et al. 2015, Durban et al. 2017. Southern resident killer whale abundance: Estimates from vessel and shore-based surveys. No error; counts have no error assoicated with them
