Analysis of Florida Keys Canal Remediation Diel Results
The analysis focuses on the diel results of a canal remediation project in the Florida Keys as of 11/01/2016. It includes measurements of %DO saturation above 42% and the average %DO saturation over a full day, with data points on control and remediated surfaces. Significant improvements are observed in the remediated section. The impact of storm events on DO concentrations is also discussed but not plotted. The comparison between control C28 and remediated C29 shows a decoupling after backfilling, indicating improvements in %DO saturation.
