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 during a two hour incubation period. 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.

We quantify metabolic rates of periphyton assemblages using 12 300mL light/dark BOD bottles per site. Ambient water is placed into six light and six dark BOD bottles. Then approxiamately 500 mm2 of periphyton is added into three light and three dark bottles, the remaining six bottles are controls. 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.

At TS/Ph5 on DATE 08-Dec-98, the Periphyton Resp STD has changed since the previous submission (v1 to v2). For TS/Ph2, no data was colleced for the following Month-Year (ex. Jan-04 = January 2004): Sep-01, Nov-01, Jan-02, Sep-02. Collections in 2005 and 2006 did not occur. Dataset Anomalies Only 2 replicates for dark control on Aug 98 sampling event at TS/Ph4. Information Management Notes This is a short-term primary production dataset and research sites have been decommissioned so there will be no subsequent data addtions to this file. This dataset replaces all previous versions of LT_PP_Iwaniec_002 original and (v1-v2). The FCE program is discontinuing its practice of versioning data as of March 2013.
