Overview
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.
Design
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.
Benefits
- 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

Lake Erie Volunteer Science Network: Building Trust in Citizen Science Programs
Citizen science programs have popped up across the United States, focusing on connecting local communities with nearby water resources and building a trustworthy data pool over the sampling period. While commonly utilized as a means of ensuring that large watersheds or lake regions are adequately sampled, the credibility and success of such programs have been called into question.

Stream velocity measurements can be combined with water level measurements to calculate stream flow and chemical parameter loads.

In the eastern basin of Lake Erie, off the coast of Dunkirk, New York, a data buoy collects valuable water quality, weather, and wave data that inform residents and regulatory groups of conditions on the water. 
 
Since 2011, Buffalo State University’s Great Lakes Center has maintained and operated the Dunkirk buoy with funding from the Great Lakes Observing System (GLOS) and field support from the NYSDEC Lake Erie Fisheries Research Unit.

Lightweight and easy to use, the SonTek CastAway offers a convenient 3-in-1 solution for measuring conductivity, temperature, and depth profiles. At a 5 Hz sampling rate, the CastAway is designed for up to 1 m/s free-fall through the water column. 
 
 With fast response and accurate conductivity, temperature, and depth measurements, the CastAway is ideal for thermocline and halocline profiling. The unit also reports salinity and speed of sound.
