Predicted detectability at a distance of 800 m as a function of ΔT or ambient noise at the nearshore (white/orange) and mid-shelf (white/blue) sites, and with the effect of site removed (black/gray). Envelopes indicate 95% confidence intervals. Panels show scenarios of a the effect of ΔT at median levels of ambient noise (c. 220 mV); b the effect of ΔT at a masking level of ambient noise (300 mV); c the effect of ambient noise under moderate stratification (ΔT = 5 °C); and d the effect of ambient noise under no stratification (ΔT = 0 °C). Rugs denote the distribution of observations within 1 °C (a, b) or 10 mV (c, d) of the given scenario
