Calling blue and fin whales have been tracked using relative travel times and amplitudes from both direct and multipath arrivals to a seafloor array of seismometers. Calls of three fin whales swimming in the same general direction, but several kilometers apart, are believed to represent communication between the whales because of signature differences in call character, an alternating call pattern, and coordination of call and respiration times. Whale call tracks, call patterns, call character…

An automated method has been developed to identify arrival times based on instantaneous frequency and amplitude and to locate calls using a grid search even in the presence of a few bad arrival times.

Blue and fin whale call source levels and propagation range in the Southern Ocean.

Blue and fin whale populations in the Southern Ocean have remained at low numbers for decades since they became protected; using source level and detection range from passive acoustic recordings can help in calculating the relative density of calling whales.

Tracking fin whale calls offshore the Galicia Margin, North East Atlantic Ocean.

Data recorded during a temporary deployment of ocean bottom seismometers (OBSs) are used in this study to monitor the presence of fin whales around the array. In the summer of 2003, ten OBSs were

Tracking blue whales in the eastern tropical Pacific with an ocean-bottom seismometer and hydrophone array.

Low frequency northeastern Pacific blue whale calls were recorded near the northern East Pacific Rise on 25 ocean-bottom-mounted hydrophones and three-component seismometers during a 5-day period; no correlation in vocalization or movement with airgun activity was observed.

Source levels of fin whale 20 Hz pulses measured in the Northeast Pacific Ocean.

No consistent increase or decrease in source level was observed over the duration of a dive and calls within these sequences that immediately followed gaps of 27 s or longer were classified as backbeat calls and were consistently lower in both frequency and amplitude.

Long-range acoustic detection and localization of blue whale calls in the northeast Pacific Ocean.

Analysis of acoustic signals recorded from the U.S. Navy's SOund SUrveillance System (SOSUS) was used to detect and locate blue whale calls offshore in the northeast Pacific to develop a simple matched filter for detecting such calls in noisy time series.

Singing fin whales tracked acoustically offshore of Southern California

Author(s): Varga, Leah McLean | Advisor(s): Hildebrand, John A | Abstract: Fin whales (Balaenoptera physalus) produce a stereotyped low frequency call (15-30 Hz) that can be detected at great range

Temporal separation of two fin whale call types across the eastern North Pacific

The 40-Hz call may be associated with a foraging function, and temporal separation between 40- and 20-Hz calls may indicate the separation between predominately feeding behavior and other social interactions.

BLUE WHALE, BALAENOPTERA MUSCULUS, VOCALIZATIONS FROM THE WATERS OFF CENTRAL CALIFORNIA

Low-frequency calls produced by blue whales, Balaenoptera musculus, were recorded in the northeastern Pacific Ocean off central California during a vessel-based marine mammal survey and when sonobuoys were subsequently deployed, blue whale calls were recorded.

Reactions of bowhead whales, Balaena mysticetus, to seismic exploration in the Canadian Beaufort Sea.

Tests with one 0.66-1 airgun showed that some bowheads move away from sources of strong seismic impulses even in the absence of boat noise, and that bowheads can detect the direction from which seismic impulses arrive.

Characteristics and seasons of blue and finback whale sounds along the U.S. west coast as recorded at SOSUS stations

Blue whale sounds were doublets, each member lasting about 19 s. ‘‘A’’ sounds mostly occurred at 19.7 Hz; ‘‘B’’ at 22.2 with a short tail at 19.8. A few individual whales appeared to call for hours

Underwater sounds from migrating gray whales were recorded from a bottom‐mounted hydrophone array and no characteristic behavior could be associated with sound production other than blow sounds during exhalations.
