Solinst Biofoul Screen
- Delrin sleeve wrapped with copper wire
- Slips onto the sensor end of the Levelogger or AquaVent
- Designed to reduce buildup of microorganisms, plants, algae, etc.
The Solinst Levelogger Biofoul Screen is an affordable option to lengthen the time a Levelogger can be deployed before maintenance is required. When a Levelogger is deployed for extended periods, especially in coastal and saltwater environments, there is the risk of biofouling. Biofouling on the pressure sensor or conductivity cell can compromise the reliability of the readings. Using the natural anti-fouling characteristics of copper, the Biofoul Screen is designed to reduce the unwanted buildup of microorganisms, plants, algae, or organisms such as barnacles and mussels.
The Biofoul Screen consists of a Delrin sleeve wrapped with copper wire. The Biofoul Screen simply slips onto the sensor end of the Levelogger, where it is held in place by friction fit. The screen allows water to freely enter the pressure sensor of any Levelogger, and the conductivity cell of an LTC.

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
As climate change lifts the sea level in the Gulf of Mexico, it’s lifting levels of enterococci bacteria on Texas’s beaches, too.
New research out of the Gulf shows that high levels of enterococci bacteria, which come from humans and other animals and can cause disease, are correlated with proximity to large human populations and sea level rise and are increasing over time.
The research highlights an area of growing concern for public health and safety on popular recreational beaches. While sea level is projected to continue rising, it’s not a guarantee that bacteria levels will as well.Read More
