<p>The present invention relates to a bathymetry device which enable a determination of water temperature as a function of the depth of the water. The invention includes a ballastically shaped plummet which has a known sinking rate and which is connected by a wire to a vehicle, such as a ship. the wire is coiled within the plummet and is connected at its probe end to an electrical temperature response means such as a thermistor. The wire may also be coiled aboard the ship and may be connected at the ship end to a sensing and indicating means which plots a temperature profile. As the ship and the plummet both move in the water the wire therebetween will remain substantially motionless.</p> |
