... measured in the 0.89–2.24 kHz band for each transmission in the DTAG acoustic recording ( Table 2 ) ( Miller et al., 2011 ). Table 2. List of data variables Four response variables were considered: probability of (1) NF active (potential disturbance) and (2) LRS behaviour (nf_prob...

...: Echolocating dolphins can use three modes of range-dependent click rate adjustment during long-range target approaches, and adjust click intensity with range, but not to perceive constant echo levels. Biosonar Click packet Dtag Interclick interval Source level Toothed whale Toothed whales...

... and accelerometer data from digital acoustic recording tags (DTAGs). Over the course of three austral summers (2014, 2015 and 2016), seventeen tags were deployed, yielding 124 h of data. We report the occurrence of Southeast Pacific type 2 (SEP2) calls, which exhibit peak frequencies, durations and timing...

... contributions of flow and ambient noise. The uncorrelated part of the noise measured in digital acoustic recording tag (DTAG) recordings related well to swim speed of a humpback whale ( Megaptera novaeangliae ), thus providing a robust measure of flow noise over a wide frequency bandwidth. By removing...

... taxa. Here, we report the first detailed quantification of echolocation behaviour during prey capture in the most studied delphinid species, a false killer whale and a bottlenose dolphin. Using acoustic DTAGs, we demonstrate that just prior to prey interception these delphinids change their acoustic...
