The Gedotech Geosub Controller is designed specifically for use with Geotech's Geosub 2 Stainless Steel Pump. It provides a safe, conditioned variable DC output power from an AC power source. Built-in sensing gives the operator accurate and precise control over the pump during sampling events.

Battery Life
An average 1000-watt gasoline generator with 1 gallon of gasoline will operate the Geosub Controller and Geotech's sampling pump at full power for 18 hours continuously. Generally, much longer run times can be expected as the controller is used to reduce water flow for low-flow sampling.

An easy-to-use programmable user interface with a bright display offers precise control over flow rates during groundwater sampling events. Site-specific settings and conditions can easily be stored and recalled for more efficient, repeatable sampling events. Rugged construction and easy-to-connect cables make setup and portability a breeze. In addition, the controller includes a user-set dry run protection feature.


  • Converts AC Voltage to variable up to 300-watt DC voltage output
  • Short circuit protection for your safety
  • Heavy duty rated power cable for years of service
  • 2-line x 16-character wide temperature range alpha-numeric digital display
  • Push button Up/Down control
  • Internal processor saves individual well parameters
  • Optional DC to AC Inverter can be connected to a vehicle battery
Questions & Answers
Does the controller need to be grounded?
Yes, the controller must be wired to a negative ground system. If using a generator larger than 2000 Watts, a grounding rod driven into moist earth must be installed and electrically connected.
What kind of power source is this compatible with?
The SS Geosub controller can be connected to any AC power source, such as an AC gasoline powered generator. A DC to AC inverter is available under the Accessories tab to connect the controller to a DC source such as a car battery.
Is the controller field serviceable?
No, The SS Geosub controller has no field serviceable components and should never be opened by an unqualified person.

Current Monitoring after the Francis Scott Key Bridge Collapse

On March 26th, according to The Baltimore Sun , a 984-foot, 112,000-ton Dali lost propulsion and collided with a support column of the Francis Scott Key Bridge, collapsing the structure. Soon after the event, search and rescue, salvage crews, and other emergency responders were mobilized after the collision. As salvage efforts progressed in early April, NOAA’s Center for Operational Oceanographic Products and Services (CO-OPS) responded to a request for real-time tidal currents data and deployed a current monitoring buoy—CURBY (Currents Real-time BuoY)—into the Patapsco River north of the Francis Scott Key Bridge.

Soundscapes of the Solar Eclipse: Citizen Science Supporting National Research

On April 8, 2024, millions of people around the world had their eyes glued to the sky to witness a historic cosmic event. The total solar eclipse captured the headlines and the minds of many who became eager to gaze at the heavens as the sky went dark for a few minutes. However, not everyone used their sense of sight during the eclipse, some were listening to the sounds of the natural world around them as the light faded from above. The Eclipse Soundscape Project is a NASA-funded citizen science project that focuses on studying how the annular solar eclipse on October 14, 2023, and the April 8, 2024 total solar eclipse impacted life on Earth.  The project revisits an initiative from the 1930s that showed animals and insects are affected by solar eclipses.

Applied Research and Innovative Solutions: Creating CHNGES at Western Kentucky University

Long-standing environmental monitoring programs have the power to support a large number of research initiatives and policy changes—however, actually starting these networks can prove challenging. Not only is starting the program difficult, but keeping things operational for decades to come has also been challenging for environmental professionals hoping to make an impact with applied research. Jason Polk, Professor of Environmental Geoscience and Director of the Center for Human GeoEnvironmental Studies (CHNGES) at Western Kentucky University, is all too familiar with this process.
