  • Dataset Abstract
    Once per year, at TS/Ph-4 and TS/Ph-5 we incubate periphyton from each site in water from each site in a complete factorial design. We quantify metabolic rates of periphyton assemblages using standard oxygen change techniques in 300mL light and dark BOD bottles in triplicate. Using YSI dissolved oxygen probes and meters, we measure dissolved oxygen change as the difference of initial and final oxygen concentrations over a two hour incubation. We calculate net primary productivity and respiration rates in units of oxygen and carbon, then normalize to the organic content (ash free dry weight) of the incubated periphyton.

  • Methods
    Sampling Description
    Once per year, at TS/Ph-4 and TS/Ph-5 we incubate periphyton from each site in water from each site in a complete factorial design in triplicate. We quantify metabolic rates of periphyton assemblages using thirty-six 300mL light/dark BOD bottles. From each site, approxiamately 500 mm^2 of periphyton is added to water from each site in a matrix design, the remaining 12 bottles are controls. Combinations for the matrix design that are used with both light and dark bottles include: TS/Ph4 Periphyton x TS/Ph4 Water ; TS/Ph4 Periphyton x TS/Ph5 Water; TS/Ph5 Periphyton x TS/Ph4 Water; TS/Ph5 Periphyton x TS/Ph5 Water; then controls soley have ambient water. Using YSI dissolved oxygen probes and meters, initial and final dissolved oxygen concentrations and times for all bottles is measured during incubation (approxiametely two hours). Incubated periphyton is brought to the lab and dried at 70 C for a minimum of 24 hours then ashed at 500 C for 3 hours. We calculate net primary productivity and respiration rates using standard oxygen change techniques to units of carbon, then normalize to the organic content (using the difference of dry weight and ash free dry weight, AFDW) of the incubated periphyton.
