Mission
• Chlorophyll a
• Algal types
• Photo library
Sampling
• Van Dorn
• 3 depths: 0 (surface), 3, 6 feet
• 4 days: 8/4, 8/18, 8/25, 8/29
• 8 sites on Lake Eau Claire
Chlorophyll a Analysis
• Filter for Chlorophyll a• Grind filter• Extract with acetone• Measure at different wavelengths:
630, 645, 665, 750 nanometers• Equation gives Chlorophyll a parts
per billion (Chl a mg/m3)
