    • A seismic source for marine seismic acquisition is described, comprising an outer cylinder having one or more apertures, an inner cylinder having one or more apertures configured to align with the apertures of the outer cylinder at one or more predetermined rotational positions of the inner cylinder, wherein an outer wall of the inner cylinder is flush with an inner wall of the outer cylinder, an axis bar coupled to the inner cylinder, wherein the axis bar rotates the inner cylinder, an actuator coupled to the axis bar, wherein the actuator controls a rate of rotation of the inner cylinder, and a gas supply coupled to the inner cylinder, wherein the gas supply provides a compressed gas inside the inner cylinder, wherein the compressed gas is released out of the seismic source such that a volume of water surrounding the seismic source is displaced at less than a predetermined rate, thereby attenuating an out of band frequency emitted by the seismic source.
    • 描述了用于海洋地震采集的地震源,其包括具有一个或多个孔的外圆筒,具有一个或多个孔的内筒,其被配置为在内筒的一个或多个预定旋转位置处与外筒的孔对准, 其中所述内筒的外壁与所述外筒的内壁齐平,所述轴杆与所述内筒联接,其中所述轴杆旋转所述内筒,所述致动器联接到所述轴杆,其中所述致动器控制所述内筒 内筒的旋转速率和与内筒联接的气体供应,其中气体供应在内筒内部提供压缩气体,其中压缩气体被释放出震源,使得围绕 地震源以小于预定的速率移位,从而衰减由地震源发出的带外频率。
