REPS Periphyton Productivity & method comparison

Monitoring periphyton indicates short term impacts on the system and provides a measure of productivity in these aquatic systems over the open water season of 2012 (May, June, July, August, September, October) and 2013 (July, August, September). This study was designed to test previously un-utilized techniques of periphyton collection in the AOSR. Sample sites are on a gradient moving closer in proximity to industry to delineate effects of natural and anthropogenic contaminants. The three measures of periphyton productivity are compared through standard chl-a and AFDM values: standard area-delimited, artificial substrate, and whole rock. Whole rock data is only collected in 2013 and so formal method comparison is focussed on samples collected within this year.

Usage Considerations or Constraints This periphyton data is sampled three different ways in sites to compare sampling methods. The whole-rock method is only tested in 2013 so a full comparison of data is only possible in 2013. Samples were not taken in all months listed for all methods each year. All samples, except whole-rock samples, were processed in the Saskatoon NLET facility.
