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
Enormous amounts of excess nitrogen hit water bodies all over the globe, including the U.S., due to runoff from agricultural and other human activities. This nitrogen can cause dead zones and harmful algal growth. Before it reaches the ocean, microbes can process and remove some of it from stream sediments, connected aquifers and tidal freshwater zones. Thanks to this process, coasts can have a decreased likelihood of harmful algal blooms.
Keeping coastal waters clean is important for many reasons, including the fact that about 60% of the U.S. population lives on coasts. But despite the importance of these nitrogen processes, researchers have not fully investigated how they work.Read More
The Chesapeake Bay is the site of recurring seasonal dead zones: areas of low dissolved oxygen where aquatic life struggles to survive if it can at all. In 2020, a dead zone in the Maryland portion of the bay was one of the smallest since 1985, when record keeping began. The hypoxic area in the Virginia portion of the bay was smaller and briefer than many years previous.
But the problem isn’t gone yet, and looking forward, climate change will play a big role in determining the size and severity of dead zones throughout the bay. It could make it harder to get hypoxia under control in some places.Read More
