Abstract
A linear sensor array is deployed horizontally on the ocean floor by first deploying a vertical array, between an anchor and a float from which the array is suspended, and then decreasing the buoyancy of the float gradually as the float is carried away from the anchor by ocean currents. The float is comprised of a suitably large volume of buoyant material such as hollow glass microspheres freely floating inside a liquid filled plastic container. To gradually reduce buoyancy, the microspheres are allowed to flow out through a neck near the top of the container while water is allowed to enter the bottom of the container through a liquid permeable membrane. The diameter of the neck is selected for optimum sinking rate of the float.
