From page 74...
... The total yearly energy in a 1-Hz band produced by 10 typical oceanographic experiments would be about 66 dB higher than the average sound level [10 log (60x600xlOOxlO)

From page 75...
... . The entire sonic energy generated by the fleet of supertankers is, therefore, about 283 dB near 50 Hz and about 328 dB near 2 Hz (dB re 1 pPa water standard)
