Whale and porpoise voices : a phonograph record

(Woods Hole Oceanographic Institution, 1962) Schevill, William E. ; Watkins, William A.

The vocal sounds of cetaceans are a little known and even less understood feature of the complex adaptation of these animals, whose ancestors lived on the dry land, to an entirely aquatic existence. Even in the clearest surface waters, sight is limited to about a hundred feet or less in daytime, and visibility ranges are mostly negligibly short for fast-swimming animals, so that they are effectively partly or wholly blinded. Therefore sound and hearing have an especially important place in their lives. Sound is used not only in direct communication, but also to a large degree in navigation and hunting (echo-location). The excerpts presented here are samples of such sounds made by eighteen species, all obtained by eavesdropping in the open sea (except for the Inia selection, which was made in captivity). These recordings have not been speeded up or slowed down, and so are true in natural frequency and time; there has been no editing or filtering except as noted.

Four hydrophone array for acoustic three-dimensional location

(Woods Hole Oceanographic Institution, 1971-10) Watkins, William A. ; Schevill, William E.

This report describes a non-rigid, floating, four-hydrophone array that can give accurate three-dimensional locations for certain underwater sound sources, particularly for those that are close. For more distant sounds, the array can indicate good directions (bearings) but range is liable to be uncertain. A system for concurrent calibration permits periodic reassessment of hydrophone positions. Appendix: Programming and mathematics for computer analysis of the array data are by Donna Ekstrand and Mary Hunt.
Sound Cut, Record Number 5702100L

(Woods Hole Oceanographic Institution, 2003-05-15) Schevill, William E.

Recording of two Short-finned pilot whales made by RG AX58 Hydrophone, WHOI battery amp, Magnemite recorder. Whistles; series of squeals.
Right whale, Eubalaena glacialis, sightings in Cape Cod waters

(Woods Hole Oceanographic Institution, 1981-06) Schevill, William E. ; Moore, Karen E. ; Watkins, William A.

Sightings of right whales, Eubalaena glacialis, in Massachusetts waters have been recorded by workers at Woods Hole Oceanographic In stitution since 1955. These observations do not represent a census, because emphasis was placed on studying the whales' underwater sounds and other activities. The number of yearly sightings varied from 2 to 165. Observations were made from aircraft, boats, and occasionally from shore.

A phonograph record of the underwater calls of delphinapterus leucus

(Woods Hole Oceanographic Institution, 1950-01) Schevill, William E. ; Lawrence, Barbara

DelphinaplMus leucas (Pallas), variously called white porpoise, white whale, or beluga, has long been known as a vociferous species. It is an arctic form, generally restricted to waters north of N. Lat. 60°, except along the coast of eastern Asia, where it ranges as far south as the offing of southeastern Sakhalin, and along the coast of eastern North America, where it is normally abundant to about the same latitudes in the St. Lawrence estuary. It was in this region, in the lower Saguenay River, Quebec, that our records were made, in July 1949. In these restricted waters we have been fortunate in finding concentrations of Delphinapterus with no other aquatic sound-makers in evidence. For this and other reasons detailed before (1949, Science, Vol. 109, pp. 143-144, Feb. 11 ), we are convinced that all the sounds heard on this record were made under water by DelphinaplMus. This particular cetacean makes a very good subject, as it is especially conspicuous both optically and acoustically, and is easy to identify at sight--and, we now submit, likewise by ear.

Sound Cut, Record Number 5402400b

Radio-tagging of whales

(Woods Hole Oceanographic Institution, 1966-05) Schevill, William E. ; Watkins, William A.

We recount here a series of attempts to tag and track whales at sea without catching them. Radio transmitters of 140 Mc were attached to the backs of whales from helicopters. Tracking the tagged whales was attempted by ship and by airplane receiving systems.
