Total Chlorophyll a for I series inlets and
outlets during the summer of 1999
Water samples were collected at 0, 1, 3, 5, 8, 12, and 16-meter depths in the monitoring lakes and 0 meters in the survey lakes. The water was returned to the lab where it was filtered through a 47 mm Whatman GF/C glass fiber filter. The filters were then placed in 10 ml of buffered 90% acetone (1 mg/l MgCO-3), and extracted in the dark, at room temperature for 24 hours. The amount of chlorophyll a was determined using a Turner Designs 10-Au -005 -CE configured with a chlorophyll optical kit
Notes: The Turner Designs 10-Au -005 -CE fluorometer was calibrated using two chlorophyll a standards of known concentrations obtained from Turner Designs. Each time samples were run the Turner Designs 10-AU fluorometer solid standard was also run.
