Distances from the M/V Gilavar at which various threshold levels are reached.

a See Fig 3.19 in [36]b See Fig 3.21 in [36]c See Fig 55 in [31]d See Fig 57 in [31]e These distances were visually interpolated or extrapolated from the figures listed above. They are very coarse and only intended to provide a rough-order estimate of distances.This table uses empirical data collected during sound source characterizations (SSCs) in the same study area in 2007 and 2008 [36, 31]. Note that regressions for sound exposure levels were not included in the reports, so the distances in this table are estimated visually from data plotted in the listed figures. CSEL = cumulative sound exposure level, SEL = sound exposure level.
