Fig. 4From: Characterization of acoustic detection efficiency using an unmanned surface vessel as a mobile receiver platformPartial effects of significant smoother functions on detection probability identified by the GAM considering thruster use and tether length. The left column depicts significant smooths for high-power transmissions: a distance and c tether length of 4.6 m as a function of distance. The right plot depicts the only significant smooth function for low-power transmissions, b distance. P-values are given for each effect (see Table 2). Shaded regions are 95% confidence intervals of model predictionsBack to article page
