Overview
The YSI 2003 Polarographic Dissolved Oxygen Sensor is designed for use with the Pro20, Pro20i, Pro1020, Pro2030, and Pro Plus instruments; cables must be ordered separately. The YSI 2003 can be used on 60520 (DO), 6052030 (DO/conductivity), 6051020 (DO/ISE), and 605790 Quatro (DO/conductivity/ISE/ISE) cables.

*The YSI 2003 comes with six membrane caps and a bottle of solution.

Questions & Answers
How does a Polarographic DO sensor work?
In a polarographic sensor, the cathode is gold and the anode is silver. The system is completed by a circuit in the instrument that applies a constant voltage of 0.8 volts to the probe, which polarizes the two electrodes. The sensor operates by detecting a change in this current caused by the variable pressure of oxygen while the potential is held constant at 0.8 V. The more oxygen passing through the membrane and being reduced at the cathode, the greater the signal increases.
Why is the Polarographic sensor warranted for 1 year while the Galvanic is only warranted to 6 months.
Galvanic sensors continually consume the anode, even when the instrument is off. The consumption of the polarographic sensor stops when the instrument is turned off, giving it a longer sensor life.
Is this sensor approved by the EPA?
Yes, the proven technology of the steady-state sensor is approved by the US EPA for compliance monitoring and reporting.
How often should the dissolved oxygen sensor be calibrated?
The DO readings should be verified before each use, and a YSI recommends performing a 1-point calibration before each use to maintain accurate readings. You can follow the instructions in the calibration guide for dissolved oxygen sensors. 
What is the main difference between the yellow vs blue caps for the YSI 2003 polarographic sensor?
The YSI 2003 polarographic DO sensor can accomodate either a blue or yellow cap. The yellow, 1.25 mil PE cap has an 8 second response time and requires a flow rate of 6 inches/second over the sensor membrane. The blue 2.0 mil PE cap has a 17 second response time and requires a flow rate of 3 inches/second. 
How often should the membrane cap be replaced on electrochemical dissolved oxygen sensors?
YSI recommends replacing the membrane cap every 2-8 weeks.

Mississippi Gulf Coast fish kill expected to continue

Officials at the Mississippi Department of Marine Resources say that a recent fish kill along the state’s Gulf coast is the largest they’ve seen, according to KVUE. The fish kill has brought dead crabs, eels and stingrays ashore. Beachgoers were disturbed by the large-scale kill, but experts explained that conditions this year were to blame. With higher temperatures and low dissolved oxygen near the sea floor, creatures that live there were more likely to be affected. The fish kill, beginning July 1, was the first of 2013 for the area. It was expected to last several more days, but lessen over that period.

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.

Green Water in Green Bay: Using Data Buoys to Monitor the Southern Bay

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.
