Provenance information | Passive Acoustic Monitoring (PAM) was carried out using a towed hydrophone at a distance approximately 200m astern of the survey vessel and at a depth of c. 2 to 5m beneath the sea surface. The towed hydrophone array consisted of a 200m-long cable containing two high frequency hydrophone elements (HP-03) situated 25cm apart in a fluid filled tube at the end of the cable. The hydrophone connected to a MAGREC HP-27 buffer-box which was connected to a National Instrument DAQ-6255 USB soundcard run through a laptop computer. The track-line of the acoustic survey effort was recorded using an external GPS receiver, which provides NMEA data to PAMGUARD (version 1.6.01 Beta) software. A dedicated acoustic observer continuously monitored the incoming audio stream both visually (audio-spectrogram) and aurally using PAMGUARD. Acoustic detections of cetacean vocalisations (both clicks and whistles) were noted, described and their time and GPS locations recorded. Raw recordings were saved continuously as .WAV files and backed-up daily on an external hard-drive. |
