First known study, identification, and characteristics of fin and blue‐whale vocalizations in the Northeast Pacific with historical notes and anecdotes

Autor: Paul O. Thompson, William C. Cummings

Publikováno v: The Journal of the Acoustical Society of America. 108:2612-2612

In 1964 we were tasked by the Navy to identify and describe low‐frequency, high‐level noise mainly in the 1/3rd‐octave frequency band containing 20 Hz. Due to AGC and other presently antiquated processing then used at Northeast Pacific sound su

Autor: Paul O. Thompson, William C. Cummings

Publikováno v: The Journal of the Acoustical Society of America. 108:2634-2634

Underwater vocalizations from a small group of fin whales were recorded from the U.S. National Science Foundation’s (NSF) research vessel ‘‘Hero’’ in Golfo de Penas, Chile, May, 1970. The most outstanding and frequent vocalizations were pat

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

Autor: William C. Cummings, Paul O. Thompson

Publikováno v: The Journal of the Acoustical Society of America. 95:2853-2853

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 or perhaps days within hydrophone ra

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

Autor: Donald K. Ljungblad, Paul O. Thompson, Sue E. Moore

Publikováno v: The Journal of the Acoustical Society of America. 71:477-482

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) and 12 day (fall) investigations. Most bowhead sound

Temporary Threshold Shifts from Tones and Noise Bands of Equivalent rms Sound‐Pressure Level

Autor: Robert S. Gales, Paul O. Thompson

Publikováno v: The Journal of the Acoustical Society of America. 33:1593-1597

In order to compare the temporary threshold shift (TTS) produced by bands of thermal noise with that produced by pure tones, eight ears (four subjects) were exposed to pure tones of 500 and 3200 cps, and to noise bands 5 cps, one‐third octave, and

Underwater Sounds from the Blue Whale, Balaenoptera musculus

Autor: Paul O. Thompson, William C. Cummings

Publikováno v: The Journal of the Acoustical Society of America. 50:1193-1198

Powerful low‐frequency sounds were recorded from blue whales, Balaenoptera musculus, off the Chilean coast. These three‐part sounds lasted about 36.5 sec, and ranged in frequency from 12.5 to 200 Hz. The sounds occurred in a repetitive pattern th

Underwater Sounds of Migrating Gray Whales, Eschrichtius glaucus (Cope)

Autor: Paul O. Thompson, William C. Cummings, Richard K. Cook

Publikováno v: The Journal of the Acoustical Society of America. 44:1278-1281

Underwater sounds from migrating gray whales were recorded from a bottom‐mounted hydrophone array. Sound‐source locations were based upon arrival‐time differences and received levels. Visual tracking corroborated sound data. Moans were the most
