TL;DR: Three tracks of whale activity using real data from one or two hydrophones have been created, and three are provided to demonstrate the method, including one simultaneous visual and acoustic localization of a sperm whale actively clicking while surfaced.

TL;DR: Timing and tracking analyses of sperm whale acoustic activity during three encounters indicate that cavitation arising from changes in ship propeller speeds is associated with interruptions in nearby sperm whale dive cycles and changes in acoustically derived positions.

TL;DR: A vector sensor module attached to the end of a 800 m towed array is used to detect and localize 1813 sperm whale "clicks" off the coast of Sitka, AK, providing unambiguous bearing estimates of two sperm whales over time.

TL;DR: The results suggest that depredation efforts might be measured remotely with passive acoustic monitoring at close ranges with significantly different acoustic behavior than naturally foraging whales.

TL;DR: An acoustic estimate of spermaceti organ size was obtained by measuring the inter-pulse interval of clicks detected from the animal and using empirical formulas to convert this interval into a length estimate, which matches the visually-derived length to within experimental error.
