Overview
The Onset differential air pressure transducer sensor measures either air pressure or velocity with the flip of a switch. Available in three installation configurations (duct, panel, or universal). Duct and panel models have two pressure and velocity range options: 0-1" WC / 0-3,000 ft/min or 0-10" WC / 0-7,000 ft/min, with seven field-selectable sub-ranges for pressure and eight for velocity. All variants are available with and without display. This sensor has an IP65/NEMA 4 environmental rating.

Carbon and Nutrient Monitoring in the Great Lakes Using Satellite Observations
Carbon and nutrients are the foundation of lake food webs and play an important role in the chemical and physical processes that shape aquatic ecosystems and various lake dynamics. Studying these cornerstones can help improve understanding of other lake conditions like harmful algal blooms, hypoxia, and phytoplankton community composition. The way in which these characteristics are monitored varies, though many rely on a proxy approach wherein parameters are extrapolated from the measurement of a different parameter. An assistant professor at Cleveland State University, Brice Grunert, is working to improve current strategies and take a satellite approach to monitoring the Great Lakes.

Restoring North Texas Streams to Historical Flows
North Texas is one of the fastest-growing regions in the state, an area that is expected to face increasing water needs. In order to meet these demands, the Upper Trinity Regional Water District ( UTRWD ) is building Lake Ralph Hall near Ladonia in southeast Fannin County, Texas. The lake has been in the works since 2003, with construction finally beginning in 2021. The population of the UTRWD is expected to grow 5-fold over the next 50 years, leading to increased water use. Ed Motley, Program Manager with the UTRWD stresses that even with conservation and reuse, new sources like Lake Ralph Hall are essential to meeting near-term and long-term water needs to support regional growth.

Science for Science’s Sake: Monitoring Ocean Energy Availability and Gulf Stream Dynamics
Scientific research often begins with a question, sometimes driven by a specific goal or application, but many scientists believe in science for science’s sake. Marine environments and physical dynamics like the Gulf Stream are popular fields of research due to their complexity and importance, presenting a unique opportunity to learn more about previously unexplored phenomena. Environmental researchers, in particular, see the value in these ecosystems, but many also grew up with a passion for the natural world, and choosing a field that allows them to interact with and learn about the environment around us is an easy choice.
