Figure 7.

Sound pressure levels at a depth of 21 m as received from a virtual source placed at the recorder's position at 210 m depth (SL = 180 dB between 18 and 22 Hz) using sound speed profile #30 (winter) of Argo float WMO 7900409. This set-up serves as a model proxy for the real, reverse situation, i.e. a source at 21 m and the recorder at 210 m depth. Map created using Arndt et al. [30,31] and Greene et al. [32].
