Overview
The Pro-Oceanus Mini CO2 instrument uses infrared detection to measure the partial pressure of CO2 gas dissolved in liquids. With pCO2 ranges from 0-1000 ppm up to 0-100%, the Mini CO2 provides the versatility needed for any application.
Mechanics
The Pro-Oceanus Mini CO2 submersible instruments are compact, lightweight, plug-and-play sensors. The instrument also measures total dissolved gas pressure (TDGP), a useful parameter for many applications and data correction.
Applications
With resistance to most corrosive liquids, the Mini CO2 can provide reliable dissolved carbon dioxide data for many applications. Flow-through and in-line adapters are also available for simple and effective industrial solutions.

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.

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.
