A data transmission from a control device to a load is carried out via a load line. The fluid conduit may be used for processing and treatment of fluids which must be treated to remove materials so that the resultant treated fluid may be reused andor returned to the earth and particularly to the water table. The seismometer or surface support vessel contains a navigation unit for directing the control unit to a desired location on the ocean bottom. The user interface builder includes a graphics generator and a display screen formatter. Area values may be generated along a longitudinal axis of the vessel, and a one-dimensional profile fit to the generated area values. A pump is fluidly connected between the mixing valve and the dispensing nozzle and includes a pump priming valve that operates on negative air pressure to clear air from the fluid lines during pump operation.
