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

Site Characteristics

The spatial extent of the dataset site coverage, and descriptions of the spatial extent and context for the data collection

  • Site Description

    The two sampling sites are located in the upper reaches of the Brown's River watershed- one on Stevensville Brook and one on the Brown's River upstream of its confluence with Stevensville Brook. Both sites are at an elevation of 1400 feet.

    Minimum Altitude: 1400

    Maximum Altitude: 1400
