• A new IFCB has been built and was deployed at UTMSI in August 2012
• The new design is smaller and lighter and more robust
• Deployed “in the can” in pier lab for improved stability.
a continuous, automated phytoplankton imaging system
Dr. Lisa Campbell, Texas A&M University
Early detection of HABs with IFCB• IFCB has provided early warning
of 6 HAB events: no illnesses reported– Dinophysis ovum in 2008, 2010,
2011, 2012– Karenia brevis in 2009 and 2011
• Campbell Lab has implemented automated downloading, processing, and classification
• Early warning email notifications* are sent to TPWD and DSHS within 4 h of sampling if cell counts > 2/mL
*not manually verified
Dinophysis ovum Karenia brevis

Drinking Water Quality:Huron Erie Corridor Waterways Forecast System
(HECWFS)Goal: • Reduce health risks and
costs associated with pollutant spills in the Lake Huron to Lake Erie Corridor
Major Elements:• Link 2d model for corridor
to NOAA Great Lakes Forecasting System
• Generate 3d public domain model
• Use 3d model to support water intake risk assessment work

Supporting Beach Swimming Advisory Decision Making
Issue: Exposure to beach swimming waters with elevated bacterial levels is a public health concern and one of economic vitality.
Goal: Develop and implement scientifically-justified, decision-support tools for accurate and defensible preemptive advisory issuance decisions.
Process:1.) Data integration and fusion
2.) Ensemble model development
Who is doing it: A partnership among beach managers, tourism interests, public health officials and the general public including…
