Questions & Answers

| Ask a Question
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.

To Protect and Preserve: Environmental Monitoring Central to Mission of Chesapeake Bay

In her 30th anniversary article about the Chesapeake Bay (Maryland) NERR, Jenn Raulin of the University of Maryland, Chesapeake Biological Laboratory, had this to say about the NERR: “CBNERR-MD is one of twenty-nine Research Reserves across the Country and along with just a handful of other Reserves is comprised of multiple sites." Former Deputy Secretary Frank Dawson who was acting manager of CBNERR-MD at the time of designation provides some insight, "The vision of the Reserve program in Maryland was to have multiple components that would reflect the diversity of the estuarine systems of the Chesapeake Bay, allow us to monitor change, research pressing issues, and provide opportunities for hands-on educational experiences.

Sensor Array Stretching Across the North Atlantic Reveals Drivers of Global Currents

Most of us are aware that the oceans of the world play a tremendously important role in both the regulation of the global climate and the uptake of atmospheric carbon. However, one might be forgiven for being less aware of the amazing complexity of the meridional overturning circulation (MOC) of the world's oceans. Scientists around the world are still learning about these drivers of our global climate system. The AMOC, that portion of the MOC in the Atlantic, is critical to average climate worldwide. Characterized by fluctuations from north to south and back again, warmer waters move northward on the globe, allowing deeper, colder waters to circulate toward more central areas.

BRUVS Capturing Deep-Reef Fish Communities

Until recently, it's been difficult for scientists to monitor, inventory, and study deep water fishes. Yet these species are critical to understanding threats posed by climate change, fishing pressure, and pollution, among other factors impacting marine life. Now, teams are using newer technologies to access and document fish abundance and diversity among deeper reef settings. Tiffany Sih , a PhD candidate from James Cook University, has used Baited Remote Underwater Video Stations (BRUVS) with lights to sample deeper habitats (54–260 m), in the Great Barrier Reef (GBR), Australia. Sih corresponded with EM about her recent work , the first study of its kind looking deeper than 100m, and what inspired her to take the deeper dive.
