Localisation of sperm whales using bottom-mounted sensors. (In special issue: Detection and localization of marine mammals using passive acoustics)
This paper describes the results of applying acoustic localisation methods to data from a free ranging sperm whale (Phyester macrocephalus) recorded using an array of five bottom-mounted hydrophones. The data analysed were supplied as part of the 2nd International Workshop on Detection and Localisation of Marine Mammals, Monaco, 2005. The localisation technique employed is based on a weighted least squares optimisation procedure applied to estimated delays. The method by which these delays are estimated in a robust manner is detailed. Three analytic acoustic models for the environment are explored and the effects of noise and model mismatch are considered.

Abstract

This paper describes the results of applying acoustic localisation methods to data from a free ranging sperm whale (Phyester macrocephalus) recorded using an array of five bottom-mounted hydrophones. The data analysed were supplied as part of the 2nd International Workshop on Detection and Localisation of Marine Mammals, Monaco, 2005. The localisation technique employed is based on a weighted least squares optimisation procedure applied to estimated delays. The method by which these delays are estimated in a robust manner is detailed. Three analytic acoustic models for the environment are explored and the effects of noise and model mismatch are considered.
