A marine cable incorporating pressure hydrophones, designed for continuous towing through the water. A marine streamer (Figure S-26) is typically made up of 96 or more active or live sections which contain hydrophone arrays separated by spacer or dead sections.
Usually a streamer is nearly neutrally buoyant and depressors or depth controllers (q.v.) are attached to depress the streamer to maintain the proper towing depth. The entire streamer may be 3–8 km in length.
