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.

Cross-Border Sewage Contaminated Flows: Monitoring the Tijuana River
The Tijuana River runs across the US-Mexico boundary, flowing into and throughout southern California, carrying with it nutrients and contaminants throughout the estuary. In recent decades, the flows have been heavily polluted with untreated sewage from the City of Tijuana. The wastewater enters the greater Tijuana River estuary, impacting coastal communities and disrupting the natural environment. In order to better understand these cross-border flows, researchers out of San Diego University sought to monitor the waterway test the capabilities of in-situ sensors to measure the contaminated water. Natalie Mladenov and Trent Biggs were two of the researchers involved in the project, deploying a real-time monitoring system in May of 2021.

Using Data Buoys to Track Sharks in Cape Cod
Despite the bad rap sharks often get in the media, they are incredibly important to marine ecosystems. Still, sharks residing in coastal, high-traffic areas can pose a risk to public safety—as a result, shark tracking and monitoring projects are often conducted in these waters. Regardless of the bad press, biologists like Gregory Skomal, a Senior Fisheries Scientist with the MA Division of Marine Fisheries, have always been interested in learning more about shark behavior for the sake of informing conservation efforts. “I was passionate about sharks as a child. I wanted to be a marine biologist, and pursued it through my education and ended up where I am today,” recalls Skomal.
