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
Is eradicating Great Lakes sea lamprey an “impossible dream?” Researchers say no
The sea lamprey’s days in the Great Lakes could be numbered.
That’s according to one researcher who took one of the first scientific looks at the possibility of sea lamprey eradication in the Great Lakes.
So, can you remove enough sea lamprey to make them disappear?
“Well the answer is we already have,” said Michael Jones, emeritus professor of fisheries and wildlife at Michigan State University. “Then there’s the obvious question: Why are they still here?”
While multiple gaps in current management techniques, like sea lamprey poisons called lampricides, could account for sea lamprey’s persistence in the Great Lakes, new technology could help sea lamprey managers eliminate inaccessible populations.Read More
The Shasta crayfish and signal crayfish are two similar looking arthropods on two very different ecological trajectories. As one spreads in abundance, originating in the Pacific Northwest and spreading throughout the world, the other has been reduced to a handful of remaining populations spread throughout one river and its tributaries.
Pacifastacus leniusculus - the signal crayfish - has met few obstacles in its widely successful expansion from the Pacific Northwest southward in California and Nevada, as well as Europe and Japan. By some expert accounts, it has reached invader status. And while invasive species are rarely good for the surrounding food webs, it’s Pacifastacus fortis - the Shasta crayfish - that’s suffered the most at the signal crayfish’s fortune.Read More
