Acoustic surveys
High resolution acoustic surveys with diving gliders come at a cost of aliasing moving targets
... The most obvious reason for the difference between the sampling performance are the diving behavior of the glider, which allows for deep targets to be sampled at close ranges, thus limiting the loss of precision in the ...

Assessing and correcting for the effects of species misclassification during passive acoustic surveys of cetaceans
... Given the general availability of cetacean species and the cost and time necessary to obtain data, obtaining more precise information regarding the true number of detections can quickly become challenging and costly. ...
