Overview
The LDI ROW (Remote Optical Watcher) is a non-contact sensor for detecting oil on water. Highly accurate and easy to maintain, the ROW detects and alerts you to unsuspecting oil spills. It provides 24/7 industrial and environmental water monitoring, whether at effluent discharge or influent intake points.
Applications
Detectable oils include motor oils, turbine oils, vegetable oils, lubricant oils, hydraulic oils, mineral oils, fuel oils, marine diesel oils, crude oils, heating oils, gas oils, bunker fuels, diesel, gasoline, kerosene, and aviation fuels.

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.
