Overall
The YSI ODO/T probe assembly pairs with the ProSolo Handheld to form a complete sampling system. Featuring integral, digital sensors, the ODO/T is plug-and-play which minimizes time spent on instrument setup. ProDIGITAL technology allows the handheld to automatically recognize connected sensors, so there is no need to tell the instrument what is connected.
Non-Consumptive Technology
The YSI ODO/T probe's technology is non-consumptive, meaning oxygen is not consumed during the measurement. Flow dependence is non-existent, and no stirring is required. The ODO sensor is not susceptible to interferences from other gases, drifts less and holds calibration longer than membrane-covered sensors. Maintenance is a breeze with a simple, threaded optical cap that is good for at least two years.
ProDIGITAL ODO/T Benefits
- Integral optical dissolved oxygen, and temperature sensors that are auto-recognized by Pro DIGITAL handhelds, reducing instrument set-up time
- Rugged Optical DO sensor cap with a 2-year warranty is pre-installed on new assemblies
- Military Spec (MS) connector and a weighted, stainless steel probe guard
- Fits in a 1-inch well with cable lengths up to 100 meters

Cal Poly, San Luis Obispo Manages Monitoring Efforts in Morro Bay
California Polytechnic State University, San Luis Obispo (Cal Poly, SLO), has been monitoring Morro Bay for decades, and while the monitoring program has changed over the years, the dedication to monitoring the bay has remained the same. 
 
The project started in 2006 as a Packard Foundation-funded initiative to monitor water quality flowing in and out of Morro Bay. The goal at the time was to use the data collected to develop and inform an ecosystem-based management plan in collaboration with the Morro Bay National Estuary Program (MBNEP). 
 
Since the estuary was the focus at the time, researchers were monitoring water flowing into the estuary from Chorro Creek and Los Osos Creek.

While the bay of Green Bay has been referred to as the largest freshwater “estuary” in the world, the watershed hosts intensive agriculture and contributes one-third of Lake Michigan’s total phosphorus load. 
 
 The Fox River flows into the bay, carrying excess nutrients largely the result of non-point source runoff from the watershed. With a history of deterioration extending well into the last century, the bay ecosystem suffered significant declines in water quality. 
 
 This, in turn, stimulated major clean-up and ongoing restoration efforts to improve water quality. Tracking these changes is an important aspect of ecosystem management.

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.
