Methods

The methods followed in the creation of the dataset, including description of field, laboratory and processing steps, and quality control procedures

Current Methods

  • Monitoring sites
    Started: 1991-10-30

    Browns River and Stevensville Brook are monitored at 1400 foot elevation on each.

  • Sample collection

    Duplicate samples of aquatic macroinvertebrates were collected using a standardized "kick-net" procedure. A sample consists of all the organisms and detritus dislodged from the substrate during two minutes of active substrate disturbance. Temperature, pH, alkalinity, and specific conductance of the water column are measured at the time the sample is collected. Organisms from the sample are separated from detritus and sorted into taxonomic groups.

    Software: Paradox software
