  • Dataset Abstract
    Periphyton accumulation rates were measured bimonthly at FCE LTER sites in Florida Bay and Shark Slough. Glass slides were used as artificial substrates for periphyton growth. Twenty slides were incubated for 2 months in triplicate periphytometers (flow-through plastic boxes) at the surface (SRS sites) and bottom (FB) at each site. Twelve artificial blades (made from transparency film) were incubated for 2 months in triplicate in specially constructed wire frames at the bottom at sites TS/PH 9, TS/PH 10 and TS/PH 11. Data are presented in terms of grams dry and ash-free dry mass per area per time. This is part of 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
    Accumulation rates are measured quarterly when water is present. Triplicate periphytometers, each containing 20 slides, were incubated at the water surface (SRS sites) and on top of the sediments (FB sites); artificial seagrass blades were incubated at Florida Bay sites. Periphytometers were placed near the markers for each site.

    Method Step

    Description
    Periphytometers and artificial blades were collected after 2 months of incubation and returned on ice to the lab. Periphyton was scraped from slides into beakers 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.

    Quality Control
    Field data are written in pencil on waterproof paper and photocopied upon return to the laboratory. They are then entered into the appropriate digital format. These data are reviewed in hard copy and digital format by the lab manager. Laboratory data are written in pencil on waterproof paper, photocopied prior to computer entry and then entered digitally in duplicate and cross-referenced to hard copy notes. Data outliers, determined by comparison to long-term variance in that parameter, are highlighted in resulting spreadsheets for examination by the principal investigator, who may discard the values.
