“…The radio signal from sono buoys was adequate for monitoring and localisation out to a typical range of 12 to 15 nmi. Received signals were digitised via a sound board (Fire face UFX, RME), and signals were recorded on a personal computer using the software program PAMGuard (Gillespie et al 2008). Three models of sono buoys were used during the voyage: 79 were AN/ SSQ-53D (Ultra Electronics), 81 were AN/SSQ-53F (Ultra Electronics: Sonobuoy TechSystems), and 200 were AN/ SSQ-955-HIDAR equipment (deployed in DIFAR compatibility mode; Ultra Electronics Sonar Systems).…”

The growing interest in generating electrical power from tidal currents using tidal turbine generators raises a number of environmental concerns, including the risk that marine mammals might be injured or killed through collision with rotating turbine blades. To understand this risk, information on how marine mammals use tidal rapid habitats and in particular, their underwater movements and dive behaviour is required. Porpoises, which are the most abundant small cetacean at most European tidal sites, are difficult animals to tag, and the limited size of tidal habitats means that any telemetered animal would be likely to spend only a small proportion of time within them. Here, an alternative approach is explored, whereby passive acoustic monitoring (PAM) is used to obtain fine scale geo-referenced tracks of harbour porpoises in tidal rapid areas. Large aperture hydrophone arrays are required to obtain accurate locations of animals from PAM data and automated algorithms are necessary to process the large quantities of acoustic data collected on such systems during a typical survey. Methods to automate localisation, including a method to match porpoise detections on different hydrophones and separate different vocalising animals, and an assessment of the localisation accuracy of the large aperture hydrophone array are presented.

“…Once calls were annotated and extracted from Raven, they were imported into PAMGUARD version 1.11.12 (Gillespie et al, 2009;Gillespie et al, 2013). We traced the fundamental frequency contour of each whistle, that is, the lowest frequency band associate with a whistle and its harmonics.…”

Divergence in acoustic signals used by different populations of marine mammals can be caused by a variety of environmental, hereditary, or social factors, and can indicate isolation between those populations. Two types of genetically and morphologically distinct short-finned pilot whales, called the Naisa-and Shiho-types when first described off Japan, have been identified in the Pacific Ocean. Acoustic differentiation between these types would support their designation as sub-species or species, and improve the understanding of their distribution in areas where genetic samples are difficult to obtain. Calls from two regions representing the two types were analyzed using 24 recordings from Hawai'i (Naisa-type) and 12 recordings from the eastern Pacific Ocean (Shiho-type). Calls from the two types were significantly differentiated in median start frequency, frequency range, and duration, and were significantly differentiated in the cumulative distribution of start frequency, frequency range, and duration. Gaussian mixture models were used to classify calls from the two different regions with 74% accuracy, which was significantly greater than chance. The results of these analyses indicate that the two types are acoustically distinct, which supports the hypothesis that the two types may be separate sub-species.
