Abstract
An automated system for periodically sampling water bodies, such as lakes, and delivering the test results to a remote computer using a communication system. In particular, the system has a variable buoyancy profiler with a dynamic buoyancy compensator responding approximately linear to a water pressure created by an external water body so as to actively or passively interact with an external force or pressure thereby moving the profiler to a target depth.

- 27. A dynamic buoyancy compensator responding approximately linear to a water pressure created by an external water body, comprising at least one sealed rigid compartment with one sealed elastic chamber having a valve and containing pressurized air therein, wherein said sealed rigid compartment is connected to each other, and a volume between an inner wall of said rigid compartment and an outer surface of said sealed elastic chamber is filled with water and connected to the external water body through at least one electrical valve.
- 30. A dynamic buoyancy compensator responding approximately linear to a water pressure created by an external water body, comprising a sealed compartment with at least one sylphon having a spring member therein, wherein a volume between an inner wall of said sealed compartment and an outer surface of said sylphon is filled with water and connected to water body through at least one electrical valve.
- 33. A dynamic buoyancy compensator responding approximately linear to a water pressure created by an external water body, comprising a sealed rigid compartment with a piston moving therein and being urged by a spring member, wherein a volume between an inner wall of said sealed rigid compartment and an outer surface of said piston is filled with water and connected to the external water body through at least one electrical valve.

36. A method for controlling a depth of a variable buoyancy profiler in a body of water comprising the steps of:
-
attaching the variable buoyancy profiler with a dynamic buoyancy compensator responding approximately linear to an external pressure created by the body of water;
connecting the dynamic buoyancy compensator to the body of water to receive the external pressure therefrom;
moving the profiler to the depth with an external force;
maintaining the profiler at the depth for a period of time to equalize an internal pressure of the dynamic buoyancy compensator with the external pressure at the depth;
terminating the external force; and
isolating the dynamic buoyancy compensator from the body of water to disconnect the external pressure. - View Dependent Claims (37, 38, 39, 40, 41, 42)

43. A method for controlling a depth of a variable buoyancy profiler in a body of water comprising the steps of:
-
attaching the variable buoyancy profiler with a dynamic buoyancy compensator responding approximately linear to an external pressure created by the body of water;
connecting the dynamic buoyancy compensator to the body of water to receive the external pressure therefrom;
pumping water inside or outside of the buoyancy compensator to equalize an internal pressure of the dynamic buoyancy compensator with a predetermined pressure or the external pressure at the depth; and
disconnecting the dynamic buoyancy compensator from the body of water to insulate the external pressure. - View Dependent Claims (44, 45, 46, 47, 48, 49, 50)
