Proportions of estimated daily expected acoustic transmissions detected by shallow (150-m depth; left panels) and deep (400-m depth; right panels) receivers from transmitters at acoustic tag range-test Station 2, located at the mouth of a deep passage (i.e., Chatham Strait) between protected inshore waters and the outer continental shelf. a Receptions by the 150-m receiver from transmitters placed 400 m from its base; b receptions by the 150-m receiver from transmitters placed at 800 m; c receptions by the 150-m receiver from transmitters placed at 1,000 m; d receptions by the 150-m receiver from transmitters placed at 1,200 m; e receptions by the 400-m receiver from transmitters placed at 400 m; f receptions by the 400-m receiver from transmitters placed at 800 m; g receptions by the 400-m receiver from transmitters placed at 1,000 m; and h receptions by the 400-m receiver from transmitters placed at 1,200 m. In each panel, solid lines are detection proportions from transmitters suspended 0.5 m (dark) and 5.0 m (light) off bottom. Dashed lines are mean detection proportions over the full transmission period
