YSI's Mike Lizotte and Tom Moeggenberg present an informative webinar about making accurate pH measurements in sampling and monitoring applications.

Topics include:
• Choosing the right sensor for your application
- Sampling vs. long-term sensor options
- Glass bulb, flat glass, and hemispherical bulbs
-  New Amplified pH sensor technology
-  Replaceable vs. refillable probes
• How to make good pH measurements
- Calibration procedures
- Using millivolts to estimate sensor life and anticipate replacement
- How to recondition and service a pH sensor
- Field measurements in Low Ionic Conditions
- Preventing biofouling on sensors

Who should attend:
• Those using submersible field sensors for water quality sampling and monitoring
• Those measuring pH for water quality concerns, including climate change, ocean acidification, acid mine drainage, aquaculture and fisheries, and NPDES compliance

Topics covered include:

■ New platforms and technology that eliminate biofouling from sensors by pumping sample water
■ Platforms that are quickly deployed with minimal resources, perfect for grassroots monitoring programs
■ Best practices for tough environments, including high-energy river deployments with bi-directional flow

Also:

■ Long-term monitoring program and the watershed process affecting Kentucky Lake, presented by Susan Hendricks of Murray State University

You should listen to this webinar if:

■ You use submersible field sensors for continuous water quality monitoring
■ You are interested in monitoring long-term water quality trends in lakes, estuaries, bays, and rivers
■ You are interested in new floating platforms as an alternative to stationary deployments

This webinar has been recorded and made available to registrants.

YSI's Mike Lizotte and Tom Moeggenberg present a free, informative webinar about making accurate turbidity measurements in marine and fresh waters.

Topics include:
•  YSI Turbidity Sensor Technology
•  Choosing the right calibration standard
•  Turbidity probe calibration procedures, and the use of offsets
•  Best practices for long-term measurements
•  Anti-fouling techniques
•  Post-calibration techniques for sampling and long-term studies
•  Q&A

Who should listen:
•  Those using submersible field sensors for water quality sampling and monitoring
•  Those measuring turbidity for storm water, construction run-off, flood events, TMDLs or other water quality concerns

Join us to learn about optical BOD technology.  This webinar will focus on optical dissolved oxygen technology and the new ProOBOD probe from YSI.

If you conduct BODs, this webinar is for you!

Tips for Selecting Monitoring Sites, Deploying Instruments, and Developing SOPs

It takes effort to collect good field data that is of known and documented quality. While it can be challenging, continuous water monitoring provides critical data for improving understanding of the natural world, protecting water resources, providing warnings, and informing water policies.

Presentation of how to improve monitoring techniques to collect the best quality data possible.

Topics covered:
• Understanding sites and installations
• Instrument functionality and quality assurance
• Data management and standard operating procedures

You might be interested in this webinar if:
• You are transitioning from a sampling program to a continuous monitoring program
• You are new to continuous monitoring
• You conduct continuous monitoring and would like to learn about procedures recently developed by the Aquatic Sensor Workgroup.

Slides are now available.

The CastAway-CTD provides instant temperature, salinity and sound speed profiles. Oceanographers, hydrologists and surveyors now have the ability to quickly collect data from any dock, bridge or boat. Simply drop the CastAway in the water, pull it up, and have conductivity, temperature and depth measured in minutes!

Webinar includes a Software Demonstration - See Actual Data

This free webinar discusses low flow purging to obtain representative samples.

Gathering a representative sample helps ensure more accurate data and results in better sample repeatability over the course of a study.

This free webinar discusses two case studies for monitoring run-off and turbidity in streams and rivers during construction projects and stormwater events.

- Review new US EPA discharge regulations and erosion control rules and how these affect water quality monitoring and storm water compliance at various sites.

- Learn how to easily set up and collect in-situ, real-time turbidity data for monitoring sediment at upstream and downstream of construction sites and before, during and after storm events.
