The DTAG was developed by WHOI principal investigators in 1999 with funding from ONR and WHOI endowment. This non-invasive tag records the sounds heard, and made, by the marine mammal together with its depth and orientation (i.e., pitch, roll, and heading), in a synchronized fashion throughout the dive cycle.

    Echolocation clicks of free-ranging Cuvier's beaked whales (Ziphius cavirostris)
    (Acoustical Society of America, 2005-06) Zimmer, Walter M. X. ; Johnson, Mark P. ; Madsen, Peter T. ; Tyack, Peter L.
    Strandings of beaked whales of the genera Ziphius and Mesoplodon have been reported to occur in conjunction with naval sonar use. Detection of the sounds from these elusive whales could reduce the risk of exposure, but descriptions of their vocalizations are at best incomplete. This paper reports quantitative characteristics of clicks from deep-diving Cuvier's beaked whales (Ziphius cavirostris) using a unique data set. Two whales in the Ligurian Sea were simultaneously tagged with sound and orientation recording tags, and the dive tracks were reconstructed allowing for derivation of the range and relative aspect between the clicking whales. At depth, the whales produced trains of regular echolocation clicks with mean interclick intervals of 0.43 s (±0.09) and 0.40 s (±0.07). The clicks are frequency modulated pulses with durations of ~200 µs and center frequencies around 42 kHz, –10 dB bandwidths of 22 kHz, and Q3 dB of 4. The sound beam is narrow with an estimated directionality index of more than 25 dB, source levels up to 214 dBpp re: 1 µPa at 1 m, and energy flux density of 164 dB re: 1 µPa2 s. As the spectral and temporal properties are different from those of nonziphiid odontocetes the potential for passive detection is enhanced.
