A test of the detection range of acoustic transmitters and receivers deployed in deep waters of Southeast Alaska, USA

Table 1 Specifications of the six range-test stations established in Southeast Alaskan waters during the current study, including the bottom depths associated with each receiver node and its five transmitter nodes, the depths below-surface and corresponding elevation above the sea floor at which each VEMCO VR2W receiver was suspended, and the nominal distances between each transmitter node and the base (i.e., anchor) of its associated receiver node

At each transmitter node, one VEMCO V16-5H transmitter was suspended 0.5 m above the listed bottom depth, and a second V16-5H was suspended 5 m above the listed depth. For station locations, refer to Fig. 1
