Detection probability time series estimated for 1000 m transmitter–receiver distance (DP ₁₀₀₀) in Lake Huron. DP ₁₀₀₀ was estimated for weekly intervals using logistic regression. Dashed and solid lines represent paired acoustic transmitters within each receiver line. Two transmitters (tag) were moored approximately 250 m apart at each line (panes). See Fig. 1 for locations
