Questions & Answers
Which type of pressure transducer is best for monitoring water level in a well, vented or non-vented?
There are two types of pressure sensors that are typically used in monitoring wells. These are absolute and gauged pressure, or PSIA and PSIG. Absolute pressure is measured by non-vented sensors and gauged pressure is measured by vented sensors. As such, the non-vented, PSIA sensors will need to be compensated for barometric pressure changes using an external device, where PSIG sensors will vent to the atmosphere to compensate. 
What is the lifespan of the hydrophobic filter used in the Solinst LevelVent 5 Wellhead?
There is no need to replace the desiccant or filter—they are designed to provide protection from moisture over the lifetime of the instrument, while still allowing air to vent to the transducer.

Current Monitoring after the Francis Scott Key Bridge Collapse

On March 26th, according to The Baltimore Sun , a 984-foot, 112,000-ton Dali lost propulsion and collided with a support column of the Francis Scott Key Bridge, collapsing the structure. Soon after the event, search and rescue, salvage crews, and other emergency responders were mobilized after the collision. As salvage efforts progressed in early April, NOAA’s Center for Operational Oceanographic Products and Services (CO-OPS) responded to a request for real-time tidal currents data and deployed a current monitoring buoy—CURBY (Currents Real-time BuoY)—into the Patapsco River north of the Francis Scott Key Bridge.

Soundscapes of the Solar Eclipse: Citizen Science Supporting National Research

On April 8, 2024, millions of people around the world had their eyes glued to the sky to witness a historic cosmic event. The total solar eclipse captured the headlines and the minds of many who became eager to gaze at the heavens as the sky went dark for a few minutes. However, not everyone used their sense of sight during the eclipse, some were listening to the sounds of the natural world around them as the light faded from above. The Eclipse Soundscape Project is a NASA-funded citizen science project that focuses on studying how the annular solar eclipse on October 14, 2023, and the April 8, 2024 total solar eclipse impacted life on Earth.  The project revisits an initiative from the 1930s that showed animals and insects are affected by solar eclipses.

Applied Research and Innovative Solutions: Creating CHNGES at Western Kentucky University

Long-standing environmental monitoring programs have the power to support a large number of research initiatives and policy changes—however, actually starting these networks can prove challenging. Not only is starting the program difficult, but keeping things operational for decades to come has also been challenging for environmental professionals hoping to make an impact with applied research. Jason Polk, Professor of Environmental Geoscience and Director of the Center for Human GeoEnvironmental Studies (CHNGES) at Western Kentucky University, is all too familiar with this process.
