Abstract Passive acoustic surveys are becoming increasingly popular as a means of surveying for cetaceans and other marine species. These yield large amounts data, the analysis which is time consuming can account substantial proportion survey budget. Semi‐automatic processes enable bulk processing to be conducted automatically while allowing analyst reserved validating correcting detections classifications. Existing modules within Acoustic Monitoring software PAMGuard were used process (25.4...
Abstract Research in the western Mediterranean has shown that sperm ( Physeter macrocephalus ) and Cuvier's beaked whales Ziphius cavirostris are present as small, globally distinct populations face numerous threats. The eastern is not well studied, few surveys have investigated composition of cetacean communities. In this study, visual‐acoustic were conducted off coast Israel during April–May 2022 to characterize community. Sperm (three encounters), (one encounter), bottlenose dolphins...
Passive acoustic monitoring (PAM) is an increasingly popular tool to study vocalising species. The amount of data generated by PAM studies calls for robust automatic classifiers. Deep learning (DL) techniques have been proven effective in identifying signals challenging datasets, but due their black-box nature underlying biases are hard quantify. This compares human analyst annotations, a multi-hypothesis tracking (MHT) click train classifier and DL-based classify recordings based on the...
Abstract Cetaceans in the eastern South Atlantic Ocean are poorly studied. We present results from a 2 week ship-based survey Cape Town to Vema Seamount (980 km west) during October–November 2019, including visual and towed-hydrophone observations vessel, 10 days of acoustic monitoring on seamount. Fifty-two hours surveys resulted 39 encounters whale groups seven humpback, six fin one sei whale, as well four unidentified baleen whales, 18 balaenopterid whales odontocetes. Two humpback at...
The banks of Saya de Malha and the surrounding Mascarene Plateau in Indian Ocean are among least studied shallow sea water regions world. steep sloping bathymetry this region is thought to drive high levels primary productivity support a diverse range marine species. Until now, no surveys for cetaceans have been conducted waters Malha, so diversity unknown. Opportunistic visual acoustic were onboard platform opportunity, MY Arctic Sunrise, which was involved wider project document life...
The Mediterranean Sea provides habitat for globally threatened cetaceans. Hellenic Trench is an Important Marine Mammal Area, providing core sperm whales Physeter macrocephalus and Cuvier’s beaked Ziphius cavirostris . Surveys have characterized distributions of these species in near-shore areas (<2000 m deep). Sparse survey effort deeper waters during winter has allowed speculation that it not important winter. We used passive acoustic monitoring from towed arrays to document cetaceans...
