Dear Eric,

For descriptions of echolocation clicks, you may wish to consult:

Schotten, M., Au, W. L., Lammers, M. O. and Aubauer, R. (2004). Echolocation Recordings and Localization of Wild Spinner Dolphins (Stenella longirostris) and Pantropical Spotted Dolphins (S. attenuata) using a Four-Hydrophone Array. In Echolocation in Bats and Dolphins, eds. J. A. Thomas C. F. Moss and M. Vater), pp. 393-399. Chicago: University of Chicago Press.

for whistles:

Oswald, J. N., Barlow, J. and Norris, T. F. (2003). Acoustic identification of nine delphinid species in the eastern tropical Pacific ocean. Mar. Mammal Sci. 19, 20-37.

As a supplement for a recently published open access article (see link) on managing bioacoustic information, my colleagues and I compiled a list of entry points into the literature for a wide variety of species that we work on.  These references are the ones that we provided for pantropical spotted dolphins.

Best regards,

Marie

Thank you all.

Many thanks, Marie! Your info was great help.

Best,

Eric

There are two more papers dealing with Stenella sounds, even though not S. attenuate:
