FIG. 1.

The spatial layout of the AUTEC hydrophones that were recording during the collection of the primary survey data, represented by small crosses. Also shown as dots (perceived as solid lines) are the locations of the tagged Blainville’s beaked whales when each click recorded on the DTag was produced.

FIG. 2.

Click counts per minute, summed over the 82 recording hydrophones, for the period of the primary dataset. Time is indexed as minutes since recording started. For operational reasons the data were divided into sets, and some sets (2, 5, 7 and 11) were not used. A standard lowess smooth of click counts over time is shown for the sets used. The small black vertical dashes (“∣”) are scattered minutes within the 8 sets used which were faulty and hence removed from the data. The sample periods used for the estimation of the false positive proportion are represented by “”. The limits of each day and set are represented by dotted and dashed lines, respectively.

The estimated detection function. Partial plots (on the response scale) of the fitted smooths for a binomial GAM model with slant distance and a 2D smooth of hoa and voa. For the top left plot, the off-axis angles are fixed at 0, 45, and 90° (respectively the solid, dashed, and dotted lines). Remaining plots are two-dimensional representations of the smooths, where black and white represent respectively an estimated probability of detection of 0 and 1. Distance (top right panel) and angle not shown (bottom panels) are fixed respectively at and .
