Summary

Description
English: Patterns of acoustic pressure variance as a function of the elevation angle θa for an ocean wave period of 10 s, given by the different theories without ocean bottom, in cartesian (A), and polar (B) representation. Note that when the radiated power is considered, these patterns must be multiplied by sin θa before integration over θa , as given by eq. (52). In general, as given by eq. (30) the radiated power is also a function of the relative azimuth of the first ocean wave train φ and the azimuth of the radiated acoustic power φ2 . The same figure is shown in Brekhovskikh et al. (1973, here BGKN73). The WG06 curve corresponds to Waxler and Gilbert (2006), and "this paper" is De Carlo et al. (2020 https://doi.org/10.1093/gji/ggaa015 ) for more details.

Acoustic power per solid angle radiated as microbarom by ocean waves. Left: log scale as a function of the elevation angle (zero is vertical). Right: linear scale in polar coordinates. DIfferent theories give different curves.
