Phosphorus Offsets

phosphorus-offset-classes
Phosphorus offset classes based on the data distribution

Total Phosphorus (TP) had site-specific targets that used medians and geometric means, and the results are reported as offsets from the established target by year and twenty years for each sublagoon. The central tendencies (median and geometric mean) for each station was calculated from time-series data for each individual year as well as the twenty years.

Offsets from the target data were calculated from the central tendency and data were averaged for each sublagoon annually and for the entire twenty years. The frequency distribution of the data, as shown in the figure, provided guidance to create TP scores.
