ACCF Data Protocols

Sample ACCF data protocol

ACCF’s field-based science education program, an important part of Our Place on Earth, trains and empowers students to make a difference with the science they do. We accomplish this by modeling how professional scientists actually collect, store, and analyze scientific data, using consistent protocols, or standards and procedures.

Below is a summary of ACCF data protocols effective 2016-17, divided into GLOBE-based protocols ACCF has adopted (organized by GLOBE earth system; ACCF is an official GLOBE Partner), protocols ACCF has developed for our nine Landsat plots, and other ACCF-based protocols. Links are provided where relevant.

  • GLOBE protocols
  • Landsat plot protocols
    • Land cover: Site characteristics, canopy/mid-level/floor vegetation, and count/map of all canopy tree species within 5m radius sample site located within nominal 90 x 90m Landsat plots. Selected numerical data are uploaded via Survey 123 app to our ACCF ArcGIS Online group for storage, mapping, and visualization.
    • Microclimate: Air temperature and relative humidity, stored at 15 minute intervals, are collected near the centroid of the 5m radius sample site via Kestrel Drop devices, with data downloaded to Kestrel Connect device app. Maximum/minimum temperature and humidity over collection period are uploaded via Survey 123 app to our ACCF ArcGIS Online group for storage, mapping, and visualization.
    • Wildlife: Via Bushnell 24 hr trail cameras placed near the centroid of 5m radius sample sites, wildlife sightings will be collected and entered into an iNaturalist.org project for the ACCF site. (Note: wildlife sightings via mobile devices will also be entered into iNaturalist, and sightings via our permanent ACCF saddle trail camera are entered into the iNaturalist project for the ACCF saddle.)
    • See also surface temperature and soil temperature GLOBE protocol above, to be performed on 5m radius sample sites.
  • Other ACCF protocols
    • Riparian trees: Trees in the Alder Creek riparian area, with initial data attributes following the Portland Parks and Recreation Tree Inventory Project, and additional attributes added to include information of interest to students such as adopt-a-tree friends, birdhouse presence, etc. These data are uploaded via Survey 123 app (with geolocation determined via grid to improve accuracy) as a special layer to our ACCF ArcGIS Online group for storage, mapping, and visualization.
    • Stream discharge: Streamflow in gallons per minute on the Alder Creek and Jordan Creek streams (and selected comparison streams), following Georgia Adopt A Stream measurement protocol as adjusted for smaller-discharge streams on the ACCF site. Data entered into Google Form for storage and analysis via Google Sheet, and compared to ACCF GLOBE hydrosphere data noted above, as well as ACCF GLOBE atmosphere data such as precipitation events.
