Abstract
A marine seismic housing having cleats for anchoring geophone sensors to the seafloor, and a method for placing the geophone sensor on the seafloor. The housing is attached to the bottom cable and is lowered into contact with the seafloor. The cleats puncture the seafloor upper surface to improve the coupling between the sensor and the seafloor. The cleats can have different shapes and lengths, and can be integrated within the housing or can be detachable. The housing exterior surface can comprise multiple flat surfaces for enhancing the housing coupling to the seafloor and for increasing the housing stability relative to the seafloor.
