ABSTRACT:
An apparatus and method for supporting an oceanographic sensor system employing a frame indirectly attached to a vessel so as to follow the forward motion of the vessel, one or more floats independently supporting the frame, and one or more sensors mounted on the frame. In one embodiment the apparatus is used as a hydrographic survey system and includes an A-frame attached to and projecting over the bow of a vessel, a boom, two or more catamarans rotatably attached to the boom, two or more Kevlar lines extending from the apex of the A-frame to tow points above the point where the catamarans are attached, two or more nylon lines attached at one end to the tow points and at the other end to the side of the vessel such that the Kevlar and nylon lines act in conjunction to pull the boom along the vessels path and one or more transducers rotatably mounted on said boom. In another embodiment, a data processor and a computer are linked to the transducers of a hydrographic survey system so as to produce a sounding including a depth measurement for each position on the bottom and a display linked to the data processor and computer such that the depth of each position is identified by a unique color.
