Abstract: The present invention is directed to a hydrophone streamer (100) towable from a marine vessel on a body of water. The hydrophone streamer (100)comprises a plurality of hydrophones (102)electrically connected in parallel. Each hydrophone (102) further comprises a normally-closed pressure activated switch (108) connected in series with a hydrophone sensor (104). Each pressure switch (108) is calibrated to open at a predetermined depth in the body of water thereby disabling the associated sensor (104) without affecting operation of other hydrophones (102) in the streamer (100).
