  • Dataset Abstract
    Periphyton assessments were conducted and recorded for each throw. Periphyton volumes, cover, type and composition were recorded, along with some general observations of the area. Periphyton samples were brought back for processing, and archived for soft algae, diatom, chlorophyll a, biomass and nutrient analysis.

  • Methods
    Sampling Description
    Water properties was measured using a pH meter. Soil and mat type is assessed, and periphyton is measured using a graduated cylinder. Periphyton type and composition (benthic, epiphytic, floating, green and floc) are recorded, along with coverages. A 120mL sample is brought back in either a nutrient cup or whirlpac and processed in the lab for chlorophyll a, soft algae and diatom, biomass and nutrient analysis.

    Description
    Water pH and temperature were collected in the field. Soil and mat type is assessed, and periphyton is measured using a graduated cylinder. Periphyton type and composition (benthic, epiphytic, floating, green and floc) are recorded, along with coverages. A 120mL sample is brought back and processed in the lab for chlorophyll a, soft algae and diatom, biomass and nutrient analysis. A large graduated cylinder is used to measure periphyton volume, which is then brought back in either nutrient cups or whirlpacs. Samples are picked through for vegetation, after which they are homogenized using a hand blender. Samples are then archived as five subsamples for later analysis: chlorophyll a (vacuum-filtered on GF/F filter, frozen, then run through a spectrofluorometer), dry weight/ash weight (placed in labelled aluminum boat and dried in an oven for 3 days at 80 degrees C, weighed, then ashed at 500 degrees C for an hour and a half and weighed again), soft algae (placed in labelled microvial and frozen until counting and identification using light microscope), diatoms (placed in labelled tube and frozen until acid digestion, slides are made and diatoms are identified and counted under light microscope), and nutrients (placed in labelled plastic cup, dried in oven at 80 degrees C, then ground and run for TP using a spectrophotometer)

    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.
