— Underwater acoustic harassment devices (AHDs) are designed to deter seals from attacking fin-fish aquaculture cages. They may also be unintentionally disturbing non-target marine mammals. As the distance from the sound source increases, the rate

Underwater vocalisations of Weddell seals Leptonychotes weddellii were recorded approximately 1400 km apart at Casey and Davis, Antarctica. Recordings were made during the 1992 and 1997 breeding seasons at Davis and during the 1997 season at Casey. T

Seal interference with Atlantic Salmon (Salmo salar) aquaculture cages is a financial burden to the industry. Harbor seals (Phoca vitulina) on haul-out sites along portions of the New Brunswick coastline of the Bay of Fundy, Canada, were counted duri

Pure-tone hearing thresholds of a harbour seal (Phoca vitulina) were measured in air and underwater using behavioural psychophysical techniques. A 50-ms sinusoidal pulse was presented in both white-noise masked and unmasked situations at pulse repeti

Aerial surveys of hauled-out harbour seals (Phoca vitulina)were conducted along the mainland New Brunswick coast of the Bay of Fundy, 1–2 times monthly from January to mid-December 1987. A gradual summer increase and autumnal decrease in seal numbe

The effects of signal onset/offset envelope on the underwater hearing thresholds of a harbor seal (Phoca vitulina) were measured. Pure-tone, 540-ms pulses at 2, 4, 8, and 16 kHz were presented as test signals. An ANOVA revealed that there were no sig
