This application is directed to a probe used for measuring groundwater characteristics such as temperature and conductivity, and for collecting a groundwater sample. The probe also has a shielding device that allows the probe to be driven into a hard underwater surface without damaging the probe. A deployment rig for accurately placing the probe into the underwater surface is also disclosed. The application is further directed to a method for placing a probe and measuring groundwater characteristics. An external screen membrane used with the probe allows accurate groundwater characteristic measurement by filtering particulate matter. The probe and external screen membrane allow for in situ measurement and monitoring.

Groundwater evaluation tools and methods of groundwater evaluation

A Trident Probe Groundwater Exchange System (NC#096456). The apparatus includes a groundwater conductivity sensor, designed to determine a groundwater conductivity surface; a water conductivity sensor, designed to determine a surface water conductivity groundwater; a temperature sensor, designed to determine a groundwater temperature; a surface water temperature sensor, designed to determine a surface water temperature; and a processor operatively coupled to a plurality of sensors and designed to receive information from the plurality of sensors.

An ultrasonic flow meter has been adapted for such measurements in the submarine environment. Connected to a collection funnel, the meter houses two piezoelectric transducers mounted at opposite ends of a cylindrical flow tube. By monitoring the perturbations of fluid flow on the propagation of sound waves inside the flow tube, the ultrasonic meter can measure both forward and reverse fluid flows in real time. Laboratory and field calibrations show that the ultrasonic meter can resolve groundwater discharges in both the forward and reverse directions on the order of 0.1 &#x3bc;m/s (&#x3c;1 cm/d), and it is sufficiently robust for deployment in the field for several days. Data collected with the meter elucidate the temporal and spatial heterogeneity of submarine groundwater discharge and its interplay with tidal loading and other driving forces. A negative correlation between the discharge and tidal elevation can be observed.
