Picture #010 in A Day in the Life of a Tomography Mooring

010 The source package cage is laid down and dragged to the stern of the ship to prepare its deployment. The white, 4-element hydrophone array cable is zig-zagged up and down the deck for its deployment and to be attached to the electronics package in the cage. The bitter end of the mooring line is held to the cleat at lower left. The black thing on the hydrophone cable near the lower left corner of the cage is an acoustic interrogator which is used to track the position of the source cage.
