Questions & Answers
How does a Galvanic DO Sensor work?
In a Galvanic sensor, the cathode is silver and the anode is zinc. The two materials are dissimilar enough to self-polarize and reduce oxygen molecules without an applied voltage. This is similar to how a battery works. The system uses a meter to read the electrical signal and the signal is proportional to the amount of oxygen passing through the membrane.
Why can the Galvanic sensor be used immediately after it is powered on?
The Galvanic sensor contains silver and zinc. These two materials are different enough to self-polarize without added voltage. This allows them to be used immediately instead of waiting on the anode and cathode to polarize.
I am having trouble getting an accurate reading, what can I be doing incorrectly?
The steady-state sensor reduces oxygen, meaning it is flow dependent. The sensors require stirring or sample movement to produce accurate readings.
Is there a blue 2.0 mil cap available for the 2002 galvanic DO sensor?
Yes, part 605914, is a 2.0 mil cap that can be used with the 2002 galvanic dissolved oxygen sensor.

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. [caption id="attachment_38996" align="alignnone" width="940"] HRWC volunteers measure stream velocity across a subsection of Woods Creek, a tributary of the Huron River near Belleville, Michigan. Stream velocity measurements can be combined with water level measurements to calculate stream flow and chemical parameter loads.

Monitoring Lake Erie’s Eastern Basin: Building Long-Term Data and Real-Time Public Solutions

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. [caption id="attachment_38976" align="aligncenter" width="940"] The Dunkirk Buoy viewed from the research vessel after being deployed in early spring.

SonTek CastAway-CTD Meter Review

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.
