Abstract:
1. A method for deploying a sensor array on an ocean floor, said array including a cable and a plurality of sensors attached to said cable, said method comprising the steps of: A) providing a semi-cylindrical frame, said semi-cylindrical frame having a float end and a plow end, said semi-cylindrical frame further defining a longitudinal axis, and being formed with a storage space for receiving said array; B) attaching a plow assembly to said plow end of said frame, said plow assembly including a sensor chute portion and a blade portion, said blade portion extending below a plane that is coincident with said longitudinal axis, said chute portion extending above said plane; C) inserting said array into said storage space for deployment, said array, said plow assembly and said frame combining to establish a weight W; D) pivotably attaching a float to said float end, said float having a buoyancy force F E) providing a propulsion force F F) dragging said plow assembly along the ocean floor so that said blade portion digs into the ocean floor to establish a trench therein, while the chute portion remains above the ocean floor; G) routing said payload through said plow assembly during the accomplishment of said step D), so that said cable passes through said blade portion and said sensors pass through said chute portion; and, H) burying the cable in the trench.
