Abstract
A method and apparatus for measuring profiles of ocean properties. The apparatus includes a stationary surface buoy to which a weight and cable are attached, the sensors traverse the cable by means of a hydrofoil the pitch of which is varied by a pressure activated sensing system. The apparatus is adapted for use under pack ice or ice bergs. The method is that of moving the sensors in a vertical direction along a guide cable beneath a surface buoy. The cable can hang from the pack ice or be buoyed upward from an anchor on the sea floor.
