Sound velocity and sound absorption data are presented. The data support the notion that some refraction of ultrasound will occur in the melon as the sound velocity of the head oil, comprising 80% of its weight, is lower than that of sea water. Deducing from these results the lens action of the melon seems not to be strong enough to explain the high directionality of the sound emitted in echolocation along, but suggests a cooperative refraction and reflection model. The data furthermore indicate a strong dependence on water temperature of the refractivity of the melon. An attempt is made to correlate the chemical composition with the sonic properties of the oil.<\/jats:p>\n               <jats:p>Subject Classification: [43]80.45, [43]80.50; [43]80.20.<\/jats:p>","DOI":"10.1121\/1.381119","type":"journal-article","created":{"date-parts":[[2005,10,3]],"date-time":"2005-10-03T22:15:53Z","timestamp":1128377753000},"page":"755-758","update-policy":"http:\/\/dx.doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":16,"title":["Ultrasonic studies on the head oil of the North Atlantic pilot whale (Globicephala melaena melaena)"],"prefix":"10.1121","volume":"60","author":[{"given":"Jonas","family":"Blomberg","sequence":"first","affiliation":[{"name":"Department of Biochemistry, Faculty of Medicine, University of G\u00f6teborg, S\u2212400 33 G\u00f6teborg 33, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bo Nordy","family":"Jensen","sequence":"additional","affiliation":[{"name":"Kemiskt Laboratorium III, H.
