Abstract:
PURPOSE: A boomer for marine seismic survey is provided to improve the efficiency of the marine seismic survey by properly dealing with situation according to a work condition, a work space, a water depth, and a survey purpose. CONSTITUTION: A transducer combining unit(31) is located on the lower side of a board floating on the surface of water and combines or separates a transducer(10a). The transducer combining unit is formed according to the left and right weight center of the board. A transducer combining device(40) mounts the transducer on the transducer combining unit. A holder(30) is mounted on the lower side of the board and controls the distance from the lower side to the transducer combining unit.
