Overview
Seametrics' DO2 is an optical dissolved oxygen sensor with built-in data logger for unattended DO monitoring applications. Utilizing fluorescence of a stable, immobilized ruthenium-based film matrix, the sensor provides precision optical transmission and detection to measure oxygen concentration in the fluid outside of the sensor. Equipped with integrated data logger and Aqua4Plus software, this sensor provides convenient, high-quality data to the user.
Benefits
- Sensor does not require water movement, flow, or frequent cleaning
- Does not require frequent calibration
- 1.66″ diameter—fits easily in 2-inch wells
- RS485 Modbus interface
- Measures dissolved oxygen and temperature
- Over 170,000 records in non-volatile memory
- Fluorescence sensor technology
- No membranes, fill solutions, replacement caps, or cartridges required
- Programmable warm-up time—easily set the warm-up time required by equipment
- Includes Aqua4Plus control software for setting up flexible recording sequences, retrieving data, monitoring real-time data, and viewing collected data

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.
