<p>The invention provides a seismic transmitter source system which includes a flotation device (10) that contains a plurality of air tight chambers (12a-c) in a serial connection. A separate one-way check valve (22a-c) is placed between each adjacent pair of the chambers. Pressurized air is continuously supplied to an end chamber. The one-way check valves enable the air to pass to the remaining chambers in one direction. A transmitter subarray containing a plurality of spaced apart transmitters (52) is suspended from the flotation device by means of several pivotly connected links (72a-n). The front end of the transmitter array is connected to a point near the front end of the flotation device. During operation, the seismic transmitter source system is pulled from a tow point (99) located at the front of the flotation device, pulling both the flotation device and the transmitter subarray in substantially a horizontal straight line position while maintaining the transmitter subarray at a near constant depth below the water surface.</p> |
