Propagation Loss Assessment of the BEARING STAKE Exercise

Bearing Stake Acoustic Assessment

“…Figure 2.2.1 of Pedersen and Yee (1979) indicates that these noise levels were within 0.5 dB of each other over the frequency range from about 15 to 100 Hz.…”

“…Our overall assessment of the ranking of events is Al, S2, P3, S1 or P1, A3, and I A2. The more detailed analyses of Pedersen and Yee (1979) indicate that the propagation losses for events A2, A3, S1, and P1 are generally larger than those of the highest loss events at any of the other BEARING STAKE sites.…”

“…Within length constraints, data and analyses are provided to support conclusions. The principal investigators' report (Pedersen and Yee, 1979) provides more data, a more detailed discussion of the analyses, and a number of additional topics of relatively minor importance. The second major section of this chapter treats the various BEARING STAKE sites on an individual basis while the last section makes assessments based on all the sites.…”

“…Chapter I includes an outline of the exercise. Chapters II through VII contain condensed statements of the major environmental and ocean acoustic observations which are presented in detail in individual, separate reports by the principal investigators (Fenner and Cronin, 1978;Hamilton and Bachman, 1979;Mitchell et al, 1979;Pedersen and Yee, 1979;Wagstaff and Aitkenhead, 1979;Neubert, 1978a, b,c,d;. This chapter represents a final stage of condensation and amalgamation of the material.…”

“…(U) Chapters II through VII are condensed statements of material presented elsewhere in greater detail by the principal investigators (Fenner and Cronin, 1973;Hamilton and Bachman, 1979;Mitchell et al, 1979;Pedersen and * Yee, 1979;Wagstaff and Aitkenhead, 1979;Neubert, 1978a,b,c,d; . The material prepared for these chapters by the principal investigators was edited to bring some degree of conformity to the style of presentation (to assist the reader), but the sections were allowed to retain a great deal of their individuality.…”
