Fig. 6

Detection probability in function of the distance between receiver and transmitter for different hourly tidal phases. The tidal cycle was subdivided in hourly tidal phases. Each plot represents a subsequent hourly tidal phase. No distinction was made between neap tide, spring tide or intermediate tide. The detection probability was estimated using the developed logistic submodel of the pSEM under median conditions of noise, water depth and tilt angle for all the considered tidal phases. For each tidal phase the distance at which the detection probability was 50% was given (D50). HW and LW stand for high water and low water, respectively. R code to create this figure was adapted from [50]
