Since the completion of this work (the experiment in 1979 and initial publication in 1981), several authors have discussed the role of down-slope enhancement and wind generated ambient noise on the midbasin ambient noise field. Dashen [R. Dashen and W. Munk, “Three Models of Global Ocean Noise,” J. Acoust. Soc. Am. 76, 540–554 (1984)], surveys three possible mechanics: scattering, down-slope transmission, and ducted transmission from high latitudes. Bannister [R. W. Bannister, “Deep Sound Channel Noise from High Latitude Winds—The ‘Missed’ Component?” (to be published)], discusses the role of high-latitude wind-generated noise and ducted transmission on the vertical arrival structure of the midbasin noise field. Finally, a summary of transmission characteristics and measured noise horizontal-vertical directionality was prepared [W. M. Carey, R. A. Wagstaff, B. Brunson, and M. Bradley, “Low Frequency Noise Fields and Signal Characteristics,” Proceedings of the Symposium and Ocean Seismo-Acoustics, 10–14 June 1985 (Plenum, New York, 1985)], by this author, stressing the contribution from both surface-shipping and wind-generated noise.
