    Article Snippet: Our 50% and520 75% quantiles are encompassed in the spectrum levels presented by National Research Council et al.521 (2003) for 3 classes of tankers, as well as merchant and fishing classes, based on the RANDI model522 (Wagstaff, 1973; Breeding et al., 1994) parameterized with data from Emery et al. (2001) and Mazzuca523 (2001).

    Comparison:

    Article Title: Ship noise in an urban estuary extends to frequencies used for echolocation by endangered killer whales
    Article Snippet: Below 300 Hz, our median values524 lie between the fishing and merchant class levels of National Research Council et al. (2003); at higher525 frequencies – up to 1,000 Hz, the upper limit of their estimates – our median values are above their526 merchant class but below their intermediate tanker class (length 153-214 m, speed 7.7-9.3 m/s). .. Overall,527 this comparison suggests that our median spectra validate the RANDI model as parameterized in National528 Research Council et al. (2003) at intermediate frequencies (100-1,000 Hz), but below 100 Hz our median529 levels are lower (by about 5-30 dB re 1 μPa2/Hz @ 1 m) than the RANDI model predicts for all classes530 except fishing vessels (length and speed bins of 15-46 m, 3.6-5.1 m/s).531 Other noticeable differences between our population mean spectrum levels and those modeled in532 National Research Council et al. (2003) are the frequency of the peak power, the general slope of the533 spectra above the peak, and secondary peaks resolved in our data. .. While our spectra peak near 50 Hz,534 the peak power in the spectra of National Research Council et al. (2003) occurs slightly lower, at 30 Hz.535 Between 100 and 1,000 Hz, the slope of our median spectrum is -12 dB re 1 μPa2/Hz @ 1 m per decade,536 nearly three times less steep than the slope of -35 dB re 1 μPa2/Hz @ 1 m per decade in National537 Research Council et al. (2003).
