A combination of visual observations and recent advances in passive acoustic technology were used to locate Antarctic blue whales, whilst simultaneously using active underwater acoustics to Habitat use, movement and residency of bull sharks Carcharhinus leucas were determined using satellite pop-up archival transmitting (PAT) tags throughout coastal areas in the U.S., Gulf of Mexico Satellite tagging field work for the first field session of was conducted from May and resulted in deployment of 14 SLTDRs (5 Cuvier’s beaked whales and 9 short-finned pilot whales) in preparation for a CEE during the week of 22 May, and all preparations are in A small towed beamforming array to identify vocalizing resident killer whales (Orcinus orca) concurrent with focal behavioral observations.

A reliable aggregation of whale sharks (Rhincodon typus) takes place in waters surrounding the remote South Atlantic island of St. Helena from December to May each year, peaking in January. Using photographic identification (photo-ID), a total of individual sharks were identified over the course of the study, consisting of a sex ratio of male and female sharks, ranging from 5 to 12 m Using a small biopsy dart, samples of living dermal tissue were collected from individually identified humpback whales (Megaptera novaeangliae) in southeastern Alaskan :// Acoustic telemetry is particularly useful for investigating short term fine-scale, and long term meso-scale patterns on individual movement and behavior (Heupel et al., ; Meyer et al., ). The longer battery life of acoustic tags and often internal implantation allows individuals to be tracked over longer time scales (years rather than   Detailed information about animal location and movement is often crucial in studies of natural behaviour and how animals respond to anthropogenic activities. Dead-reckoning can be used to infer such detailed information, but without additional positional data this method results in uncertainty that grows with time. Combining dead-reckoning with new Fastloc-GPS technology should provide good

Passive acoustic monitoring (PAM) PAM using an array of hydrophones that can detect (to species level) and track vocalising animals (primarily toothed whales - especially porpoises and dolphins) could be used to track fine resolution behaviour around tidal turbines. A static, accurately positioned array of hydrophones around a   However, for low-frequency-producing baleen whales, although sound and movement (or hereafter, “acoustic”) tags provide a general acoustic context for behaviors, it is a challenge to definitively identify the individual producing a recorded sound based on the acoustic record alone when more than one animal is present (Johnson et al., This technology has broadened the range of species that have been studied, but the expense of using satellite-linked tags often places limits on the number of individuals studied. A new generation of tags, using fastloc GPS, is providing more accurate locations to permit finer scale studies of foraging behavior and habitat use (Lidgard et al Exploring movement patterns and changing distributions of baleen whales in the western North Atlantic using a decade of passive acoustic data Article Full-text available
