The In-Situ RDO PRO-X Optical Dissolved Oxygen Sensor is an extremely stable, accurate, low-maintenance optical dissolved oxygen sensor for long-term environmental monitoring. The RDO PRO-X sensor measures dissolved oxygen using the latest dynamic luminescence quenching technology that offers many advantages over Clark-type DO sensors, including stir-independence and insensitivity to interferences such as hydrogen sulfide, chloride, and ammonium. A user-replaceable sensor cap with pre-loaded calibration coefficients is replaced annually, eliminating the need for bi-monthly membrane replacements.

The In-Situ RDO PRO-X Optical Dissolved Oxygen Sensor sensor includes a 10m cable terminating in bare wires for connection to data loggers and PLC's. For custom cable lengths, the sensor is available with a Twist-Lock cable connection. Using the Twist-Lock connection, sensor cables can easily be swapped or extended using a Twist-Lock cable extender, and custom lengths are available up to 4000 feet. The sensor is constructed with inert material and pressure-rated to 500 PSI, making it an ideal solution for highly saline or deep water environments. Common applications include dam discharge monitoring, multi-point dissolved oxygen profiling, and municipal process monitoring.

Restoring Native Brook Trout in North Carolina

The North Carolina Wildlife Resources Commission ’s Inland Fisheries Division has been working to restore brook trout in the state. Coldwater research coordinator Jacob Rash, who works with the brook trout team technicians on this project, spoke to EM about the work. “In North Carolina, brook trout are our only native trout species,” explains Mr. Rash. “With that come biological and ecological considerations as well as cultural importance. A lot of folks here grew up fishing for brook trout with their relatives, so it's an important species that we work to try to conserve. We've done quite a bit of work to figure out where those brook trout populations are and what they are, in terms of genetics.

Robotic Fish May Reduce Live Fish Testing Near Hydroelectric Plants

Each year in Germany, as many as 450,000 living fish undergo live animal experiments to test how fish-friendly hydroelectric power plants in the country are. The idea is to discover how readily the fish can move through hydroelectric turbine installations in order to ultimately reduce mortality rates. Of course, subjecting live fish to a potentially deadly test to save others is a bitter irony. And it's one that a team of scientists from the RETERO research project hopes to eventually mitigate with a robotic fish for testing. EM corresponded with Olivier Cleynen and Stefan Hoerner from the University of Magdeburg about the complex flow conditions that set the parameters for the project.

Mobile HAB Lab, Citizen Scientists Building Awareness

News stories about dogs getting sick from harmful algal blooms (HABs) in lakes have caused worry among members of the public this summer more than once. But Regional Science Consortium (RSC) Executive Director Dr. Jeanette Schnars and a dedicated team are bringing awareness about HABs to the public with the Mobile HAB Lab. “We just launched the HAB Citizen Scientists program this year,” explains Dr. Schnars. “It helps us work with people, especially people who spend time at marinas frequently, that are out there all season long.” The season for boaters at Presque Isle, where RSC is located, starts in mid-May and usually continues through the beginning or middle of October.
