Abstract
A method for measuring the velocity and direction of currents in the ocean nd other bodies of water. A first vehicle travels through water and leaves behind a trail of dye. A second vehicle travels, at a later time, the same path as that traveled by the first vehicle, and measures the distance and direction to the trail of dye. The vehicles may travel either from the surfaces downwardly or from the bottom upwardly.
Claims6
A method for measuring velocity and direction of currents in a body of water comprising the steps of,
- first depositing a vertical trail of dye in a body of water having a current, said trail of dye being deposited from a moving vehicle traveling a path through said body of water, and
- then, after a time period, traversing a second moving vehicle over the same path said first moving vehicle traveled and measuring from said second moving vehicle the positions of said vertical trail of dye at a plurality of depths to determine speed and directions of currents at a plurality of depths.
