The X2-SDL Submersible Data Logger is a rugged, self-powered remote data logging system for deploying environmental sensors in lakes, streams, rivers, wetlands, coastal waters, sewers, and culverts without fear of accidental flooding. The system is configured with three sensor ports for connection to industry-standard digital interfaces including RS-485, RS-232 and SDI-12. Additional sensor inputs are available through the use of adapters. Each sensor port offers a UW receptacle with double O-ring seal for a reliable waterproof connection. Unlike many data loggers, the X2-SDL is truly submersible. The housing and battery compartment are completely sealed and waterproof.

When it comes to field ruggedness, the NexSens X2-SDL is in a class of its own. The housing is constructed of impact-resistant PVC and includes two elastomer bumpers for long-term deployment in close-fitting pipes and buoy ports. Internal circuit boards and communication modules are shock mounted and all access ports incorporate redundant sealing. The X2-SDL withstands extreme wave action, drops, floods, periodic & long-term deployment underwater, and more. When fitted for wirelessremote communication, the radio, cellular, and satellite antennas are also waterproof.

The X2-SDL can be powered autonomously by sixteen D-cell alkaline batteries. Optional solar power kits provide long-term continuous operation and solar charging. Common sensor connections include multiparameter sondes, water quality sensors, temperature strings, Doppler velocity meters, water level sensors, and weather stations. Optional integrated cellular or satellite telemetry modules offer real-time remote communications via the WQData LIVE web datacenter. There, data is presented on a fully-featured and easy-to-use dashboard. Other features include automated reports, alarms, push notifications and much more.

Digital Mayfly Data Logger Sensor Stations Monitoring Watersheds

For most humans, mayflies seem like a nuisance, hovering over the waterways as we try to enjoy them. However, for anyone hoping to monitor the health of watersheds, mayflies are important aquatic species—and now, a digital version of the mayfly is helping some scientists keep an eye on the water. Research scientist Dr. Scott Ensign , who serves as Assistant Director of the Stroud Water Research Center , spoke to EM about how the digital mayfly technology developed. “ Shannon Hicks is the engineer who started developing the Mayfly six or seven years ago,” explains Dr. Ensign.

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.
