Whales--are they destined for immediate extinction or will a workable method of controlling their harvest soon appear? In an attempt to answer these and other biological questions related to whaling, the U.S. Department of the Interior, New York Zoological Society, Smithsonian Institution, International Biological Program, and several other organizations sponsored an international conference on the biology of whales in June 1971. The conference brought together experts on cetacean biology and population dynamics of whale stocks and relevant aspects of their biology. This volume collects papers written for that conference by nineteen authors representing eight nations. The topics discussed include cetacean biology and natural history; methods of estimating the numbers of whales; population counts before, during, and after intensive whaling; recovery rates as whaling diminishes or stops; improved ways of managing whales as a resource; and suggestions for further research. There is in addition a historical chapter on the International Whaling Commission, its failures and its positive accomplishments

Whale and porpoise voices by William Edward Schevill( Recording )

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

Right whale, Eubalaena glacialis, sightings in Cape Cod waters by William Edward Schevill( Book )

2 editions published in 1981 in English and held by 9 WorldCat member libraries worldwide

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

Radio-tagging of whales by William Edward Schevill( Book )

4 editions published in 1966 in English and held by 9 WorldCat member libraries worldwide

The authors recount 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. (Author)
