Fig. 4

Modeled daily distance at 50% detectability (D₅₀, lines) at mean values of noise and ΔT observed in the mid-shelf and nearshore sites. 95% confidence intervals are indicated by the shaded areas. Red lines show the posterior distribution of the estimated D₅₀ change points. Rug denotes periods of winds greater than 6 (short black lines) and 8 (tall black lines) on the Beaufort Wind Scale (> 10.7 m/s and > 17.2 m/s, respectively), as well as dates in which receiver tending occurred (dashed red lines)
