Overview
The Solu-Blu dissolved CH4 probe can be used for long-term continuous in-situ monitoring to provide dissolved methane data for applications such as groundwater baseline monitoring and laboratory fermentation studies. The probe provides fully temperature and pressure-compensated data. Flow-through and in-line adapters are also available for simple and effective industrial solutions.
Mechanics
The measurement of a gas dissolved in a liquid is facilitated by a semi-permeable membrane that allows gases to transfer from water into a gas head space where the measurement is made. The simple yet rugged sensor allows for the monitoring of methane in a range of environments and liquids. The probe is configured for multiple data output formats to allow for rapid integration into most platforms for data transmission and collection with minimal time and effort.

In the Right Place All the Time: Greenhouse Gas Research and NTL-LTER
While researchers all over the globe have been studying greenhouse gases, there are still some areas in the field that have not received as much attention as they deserve. Emily Stanley, professor in the department of integrative biology at the University of Wisconsin and principal investigator for North Temperate Lakes Long Term Ecological Research (NTL-LTER), has spent a significant part of her career exploring a few of them. “Clearly we have a problem with greenhouse gases. What people may not realize is that streams and lakes are hotspots of global methane and CO2. Understanding greenhouse gas dynamics in these systems is important because they are vents all over the world and they are not insignificant,” said Stanley.
Testing CO2 Removal Strategies in the Pacific Northwest
The ocean plays a key role in carbon dioxide (CO2) removal and storage, also known as carbon sequestration. However, with increasing emissions, a large amount of CO2 escapes into the atmosphere, worsening climate change and leading to increases in surface temperatures. In order to mitigate some of these impacts, researchers like Ally Savoie at the Pacific Northwest National Laboratory (PNNL) are working hard to identify ways to safely improve the CO2 removal and storage capabilities in the ocean. Savoie started her career at Wright State University , where she worked in Silvia Newell’s lab examining biogeochemical cycling of nutrients in a river system. From there, she decided to pursue a master’s in marine science at the University of Southern Mississippi with Dr.
Smart Buoys Advance Climate Monitoring in Swiss Lakes
Lakes are sentinels of climate change . Globally, they are warming at an unprecedented but uneven rate, and in many places they also face direct human pressure, including from agriculture and recreation. In the Alps, scientists generally agree that climate change is of particular threat to remote lakes , where more pronounced warming threatens fragile ecosystems. Alpine Lakes in a Changing Climate Matteo Tonellotto is part of the team at the Environmental Observatory of the Italian-speaking region of Switzerland (OASI)–a multidisciplinary team of scientists, IT specialists, and chemical laboratory technicians committed to collecting, managing, and integrating high-quality environmental data.
Connecting with Nature in Real-Time at the Abernathy Field Station
Just five miles away from Washington and Jefferson (W&J) College is the 57-acre Abernathy Field Station . Generously donated by the Abernathy family in 2017, the field station has served as an outdoor lab to hundreds of undergraduate students over the years. Many classes use the Abernathy Field Station every week. For example, in BIO 111, students spend 15 weeks conducting their own research at the field station using a combination of sampling, field observations, and real-time environmental data, giving them a look into the world of science and a closer relationship with nature. “We like to start the students in the research process in their first Biology class.
