“…Although cetacean sounds were apparently well known to historic whalers (Aldrich ), the early scientific community concluded that cetaceans were mute based upon the discovery that they did not possess vocal chords (Schevill and Watkins ). It was not until after the confirmation of sound production by odontocetes (Fraser , Kullenberg , Schevill and Lawrence ) that scientists began to realize that mysticetes also produced vocalizations.…”

Consistent and well‐defined criteria for the classification and measurement of humpback whale song features are essential for robust comparisons between investigators. Song structure terminology has been well‐established and used by many authors, though at times inconsistently. This review discusses the development of the nomenclature describing humpback song and explores the potential significance of the often‐overlooked variation in song patterns. Within the hierarchical definition of humpback song, the most problematic issues arise from the inconsistent delineation of phrase types, and the use of the metric of song duration without regards to variability in thematic sequence. With regards to the former, a set of guidelines is suggested to facilitate consistent delineation of phrases. With regards to the latter, current research demonstrates that the “song duration” metric has resulted in the disregard of variability at this level, which is more widespread than traditionally reported. An exemplar case is used to highlight the problem inherent in defining and measuring song duration. Humpback song is evaluated within the framework of avian songbird research, and a shift in analysis paradigm is recommended, towards phrase‐based analyses in which sequences of phrases are treated as a salient feature of song pattern.

The present report is concerned with one of the oceanic biology subjects designated by the Navy for investigation. In compliance with the assignment the objective has been (1) to assemble, analyze and where possible correlate with environmental factors, available information from Pacific waters, and (2) upon completion of this work to prepare recommendations for further field research designed to fulfill Navy requirements. A proposed program will be presented in a separate report. Considerable interference encountered by underwater acoustic gear is now known to be of biological origin. In coastal areas, especially along coral and rocky shores, much background noise can be attributed to fish (Fish, 1948) and invertebrates (Johnson et al., 1947). But beyond the influence of land there are certain characteristic sounds which have repeatedly been associated with marine mammals. Numerous visual observations of whales and porpoises coincident with the reception of such sounds have been made, and the charting of Submarine Patrol records (Charts VII to X, pages 56 to 59) reveals that all similar unidentified contacts have occurred within the known seasonal and geographical range of common marine mammals.
