Heron barLog Barometric Pressure Logger
- Can be with synchronized with multiple dipperLogs at the same site
- dipperLog program compensates with the barLog according to time and date matches
- Fully automated interaction

The Heron barLog barometric pressure logger is designed for long-term, automatic barometric pressure compensation with the Heron dipperLog. The barLog can be used in conjunction with multiple dipperLog water level loggers at the same site.
The fully automated operation ensures that there is no need for elevation correction or post processing of any data. The dipperLog program will coordinate the barLog pressure logger with matching dipperLogs at the same site and will compsenate according to the time and date matches.

For several decades, a wetland along the Twisp River in north-central Washington has been used as a re-regulating irrigation reservoir by a landowner looking to support their crops.
“Water was diverted from a small stream into the wetland, then pumped out of the wetland to irrigate about 35 acres of hay and pasture,” said Brian Fisher, ecologist and project manager at the Methow Salmon Recovery Foundation . “The irrigation system was diverting the majority of the stream during low flows, and was creating barriers that blocked fish migration for part of the year.”
Fisher and others at the foundation worked with the landowner to change things up and use water from a well instead of continuing to divert surface water.Read More
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.Read More
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.Read More
