Variable depth automated dynamic water profiler |
摘要 |
A winch-based system is used to raise and lower a hydrological probe into a water column to automatically dynamically obtain measurement data of a water column at incremental depths over selected time intervals. The winch-based system can be powered by a relatively low-power power source to cause the electric motor to controllably operate to wind and unwind the cable at a desired rate in a manner which can pause the upward and downward movement of the probe at incremental measurement depths. The disclosure also describes related systems. Additionally, a method for enhancing the life of a hydroglogical probe by storing the probe at an immersed subsurface depth is also described.
