IDW interpolations for proportion of Bonnethead detections that occurred within the array. Interpolations are based on proportions of Bonnethead detections and represent the time periods a before the closure and construction of the rock-rubble berm at Katrina Cut, b during construction and Katrina Cut still open, and c after construction and Katrina Cut was closed off. Red circles indicate receivers wherez Bonnetheads were detected for each time period. White lines represent 50 % locations of highest activity while blue lines represent 90 % locations of highest activity
