Abstract

Sonobuoys were originally designed over 50 yr ago for submarine detection (Horsley 1989, Brown 1994) and underwater monitoring (Fusillo and Richter 1988, Atkins 1994). They were built to receive underwater sounds via a hydrophone and transmit them to shore or aircraft by VHF radio. Since then, sonobuoys have been modified and developed for research on seismic activity (Houtz and Hayes 1 984) and meteorological and oceanographic parameters (Kozak and Garrad 1985,. Steele et al. 1994). Sonobuoys have also been used for acoustic research on marine mammals (sperm whales, Physetw mcrocephalus, Watkins et al. 1985; bowhead whales, Balaena mysticetus, Cummings and Holliday
1985, Clark et al. 1986; bottlenose dolphins, Ttlrsiops truncattls, Hunter and Morris 1987; humpback whales, Megaptera novaeangliae, Frankel et al. 1995). Horsley (1989) provided excellent details on the dismantling and electronic modification of sonobuoys; however, previous reports contain little information on the modification and deployment of equipment.
