YSI IDS ProOBOD Optical BOD Probe
Features
- User-replaceable, low-maintenance sensor cap with 1-year life
- Guarded sensor - the sensor guard provides protection of the sensor tip when taking the BOD probe in and out of BOD bottles
- Self-stirring to provide representative sample and increase response times
- Free ground shipping
- Expedited repair and warranty service
- Lifetime technical support

Overview
The YSI ProOBOD Optical BOD Probe is designed for use with all models of the YSI MultiLab, including the 4010-1W, 4010-2W, and 4010-3W. Optical, luminescent technology eliminates the probe warm-up period and membrane changes. The self-stirring BOD probe has a super quiet lab stirrer that helps ensure a representative sample and improves DO response times.
IDS Intelligent Digital Sensors
The IDS sensors automatically store their unique serial number and calibration data. In addition, they also digitally process the measurement signal. The sensors can be moved from instrument to instrument and maintain their calibration data and transmit this information to the new instrument.
Benefits
- 2-year warranty
- Reliable and serviceable
- Probe body tapered to fit into a standard 300 mL BOD bottle
- Extremely quiet operation
- No warm-up time required
- Self-stirring to provide a representative sample and increase response times

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.
