The behavioral reactions of bowhead whales to distant seismic vessels not under our control, a controlled approach by a seismic vessel, and controlled tests with a single airgun were observed. On 21 occasions in the summers of 1980-84, general activities of bowheads exposed to pulses of underwater noise (107-158 dB re: 1 mu Pa) from seismic vessels 6-99 km away were observed. Activities were indistinguishable from those without seismic noise; there was no detectable avoidance. Hints of subtle…

Blue and fin whales observed on a seafloor array in the northeast pacific.

Call tracks, call patterns, call character, and swimming speeds were examined during periods with and without the presence of noise, and whale responses associated with these noises remain arguable.

Seismic operations have variable effects on dive-cycle behavior of bowhead whales in the Beaufort Sea

The surfacing, respiration and diving (SRD) behavior of bowhead whales Balaena mysticetus changes upon exposure to seismic operations. However, it is unknown whether these changes differ by season,

The behavioural response of migrating humpback whales to a full seismic airgun array

Changes in respiration rate were of a similar magnitude to changes in baseline groups being joined by other animals suggesting any change group energetics was within their behavioural repertoire, and the reduced progression southwards in response to the active treatments, was below typical migratory speeds.

Male sperm whale behaviour during exposures to distant seismic survey pulses

The behaviour of adult, male sperm whales in polar waters (69$ 20% N, 15$ 40% E) during exposure to pulses from ar emote (>2 0k m) seismic survey vessel and artificial codas is described and

Bowhead Whale ( Balaena mysticetus ) Migration and Calling Behaviour in the Alaskan Beaufort Sea, Autumn 2001–04: An Acoustic Localization Study

The westward migration of bowhead whales (Bering Sea stock) was studied during autumn 2001–04 as part of an oil industry monitoring program. An array of Directional Autonomous Seafloor Acoustic

Response of humpback whales (Megaptera novaeangliae) to ramp-up of a small experimental air gun array.

Harbor Porpoise (Phocoena phocoena) Reaction to a 3D Seismic Airgun Survey in the North Sea

The most common cetacean in the North Sea is the harbor porpoise (Phocoena phocoena). Underwater noise is increasingly recognized as a source of impact on the marine environment and seismic airguns

Effects of airgun sounds on bowhead whale calling rates in the Alaskan Beaufort Sea

This study assesses effects of airgun sounds on bowhead calling behavior during the autumn migration. In August–October 2007, 35 directional acoustic recorders (DASARs) were deployed at five sites in

Behavioral responses affect distribution analyses of bowhead whales in the vicinity of seismic operations

Aerial surveys are sometimes used to assess the densities of wide-ranging whales, as well as changes in their distributions in response to human activity. Such surveys also provide data used to




Behavior of bowhead whales summering in the Canadian Beaufort Sea was observed from an airplane and occasionally from shore during 1980-82, mainly during August, and it is hypothesized that coordinated movement may increase the efficiency of feeding on concentrations of small invertebrates.

Passive acoustic location of bowhead whales in a population census off Point Barrow, Alaska.

A sonobuoy array placed in the nearshore lead was used for locating bowhead whale sounds to determine if whales migrated past census stations beyond visual range and were uncounted, finding that most whale sounds originated beyond 2 km (CPA), where only 1% of the 242 whales were sighted.

Underwater sounds recorded from migrating bowhead whales, Balaena mysticetus, in 1979

Bowhead whale sounds were recorded from sonobuoys in the course of conducting aerial surveys of the Beaufort Sea during spring and fall migrations in 1979. Sounds were recorded over 28 day (spring)

Characteristics of marine seismic survey sounds in the Beaufort Sea

Geophysical survey vessels emit very intense pulses of underwater sound at intervals of several seconds; these noise pulses are sometimes detectable at very long ranges. Sound pulses from geophysical

Investigations of the potential effects of underwater noise from petroleum-industry activities on migrating gray-whale behavior. Phase 2: January 1984 migration

The study supplements work performed during 1983 in the Monterey, California region in determining the degree of behavioral response of migrating gray whales to acoustic stimuli associated with oil

Hearing in extinct cetaceans as determined by cochlear structure

The bony cochlea is described in representative Odontoceti, Mysticeti and Archaeoceti, with special emphasis on adaptations to high-frequency echolocation. The latter include (a) a small distance

The Noisiness of Impulsive Sounds

Four experiments were performed in an anechoic chamber to investigate the effects of duration, intersignal interval, repetition, and frequency on the perceived noisiness of impulsive signals. All


Abstract Seismic survey activities in the western Beaufort Sea, involving ships and sound production, were monitored in autumn 1982 for their possible effects on migrating Bowhead whales Balaena
