WikiWatershed is an initiative of Stroud™ Water Research Center. The Stroud Center advances knowledge and stewardship of freshwater systems through global research, education, and watershed restoration.

2. Key Terms

Last updated on 2022-07-22

  • EnviroDIY™: A community for do-it-yourself environmental science and monitoring. EnviroDIY is part of the WikiWatershed® Toolkit (see below).
  • WikiWatershed: A web toolkit designed to help citizens, conservation practitioners, municipal decision-makers, researchers, educators, and students advance knowledge and stewardship of fresh water. WikiWatershed is an initiative of Stroud Water Research Center.
  • Leaf Pack Network®: An international network of teachers, students, and citizen monitors investigating their local stream ecosystems. Leaf Pack Network is part of the WikiWatershed Toolkit.
  • Mayfly Data Logger: A user-programmable microprocessor board that is fully compatible with the Arduino IDE software; the data logger used in an EnviroDIY Sensor Station.
  • Times Series Visualization: A component of Monitor My Watershed where raw data from sensor stations are collected, analyzed, compared, and graphed. TSV allows users to make graphs that compare several variables over customizable time periods.
  • Site code: A brief and unique text string that identifies a sampling site (e.g., “DEL_PHIL”).
  • Site name: A more descriptive name for a sampling site (e.g., “Delaware River near Phillipsburg”).
  • SL### (Stroud Logger###): Unique identifier of an EnviroDIY Sensor Station built and deployed by Stroud Water Research Center.
  • Time-series data: Data points collected over time at equally spaced intervals. For EnviroDIY Sensor Stations measurements are recorded every five minutes.
  • Continuous data: Term used interchangeably with “time-series data;” it refers to the continuous stream of data generated at specific time intervals.
  • Discharge: Quantity of water flowing in a stream over time (m3/s or ft3/s).
  • Turbidity: Measure of light passage through water (i.e., measure of the cloudiness of water). Measured in Nephelometric Turbidity Units (NTU) and others (e.g., JTU, FNU).
  • Conductivity: A measure of water’s capability to pass electrical flow; it is directly related to the amount dissolved material (ions) in the water. Measured as microsiemens per centimeter (μS/cm).
  • CTD sensor: A sensor that measures Conductivity (μS/cm), Temperature (C°),and Depth (mm).
