Advice: Installation of 24 x Acoustic Receivers, Murdoch University, Lagrange Bay
Mariners are advised that 24 x Aquatic Acoustic Telemetry instruments have been deployed in Lagrange Bay from mid June, 2023 at the following locations:
Creeks and Channel Coordinates:
1. 18° 36.4342’S, 121° 46.9842’E
2. 18° 36.4775’S, 121° 47.1721’E
3. 18° 36.5730’S, 121° 46.9091’E
5. 18° 37.0459’S, 121° 46.9509’E
6. 18° 37.2503’S, 121° 47.0932’E
7. 18° 38.8336’S, 121° 46.8304’E
The above instruments are attached to a screw anchor, approx. 70 cm from the seabed. The top of each anchor is fitted with a 10 cm diam. white polystyrene float with reflective tape. A yellow EVA apple float is attached to a 50 cm rope.

24. 18° 39.1468’S, 121° 43.1640’E
The above instruments are attached to a seabed block. Three yellow subsurface df30 EVA floats are attached at approx. 2.5 m from the seabed. One df30 EVA with reflective tape and one EVA apple floats are at the surface at all times.
Provisional recovery date: February 2026.
No vessel is to moor to or interfere with the above instruments and subsurface floats at any time.
