  • Dataset Abstract
    Periphyton biomass was measured bimonthly at FCE LTER sites in Shark Slough. Fifteen 9.8 cm2 cores were removed from the floating periphyton mat and composited into a single sample. Percent aerial cover of floating periphyton was estimated visually in the field. Data are presented in terms of grams dry and ash-free dry mass per area. Total phosphorus, nitrogen and carbon concentration in the periphyton mat is also presented on a dry weight basis. This is part of a continuous data collection to test the hypothesis that phosphorus and nitrogen limit productivity at the upstream and downstream ends, respectively, of the FCE transects. Conclusions await longer-term data collection.

  • Methods
    Sampling Description
    Three random throws of the 1m square quadrat are made at each sampling site. Site, water and vegetation characteristics are recorded. Periphyton composition and volume are also recorded, and representative volume is brought back to the lab for processing and analysis

    Method Step

    Description
    Periphyton was characterized, measured and collected from three random throws in each LTER location. Periphyton was picked through for associated macrophytes and homogenized in distilled water. Subsamples were taken for measurements of dry mass, ash-free dry mass, chlorophyll a, species composition and total nutrient (C, N, P) content.

    Instrumentation
    1m square PVC quadrat, 2000mL graduated cylinder, sampling bags
