Relative effects of received CSEL_10-min on call localization rate, for all five sites.

(A), (B), and (C) (sites 1, 3, and 4, respectively) show the data for sites with nearby airgun use, while (D) and (E) (sites 2 and 5, respectively) show the data for sites that only received relatively distant airgun pulses (see text). All four years of data are combined. Each point represents a cell-time interval, and shows the number of localized calls detected during that time window as a function of the received CSEL_10-min. The two thresholds are shown with black vertical lines and the crosshatched areas are the 95% confidence intervals. The orange and purple numbers in each plot are the numbers of cell-time intervals with zero versus one or more localized calls per 10-min period, respectively. See text for more information.
