    • Southeast Alaska Network water quality raw sonde data for monitoring year 2021 (FQ_E)

    Metadata Updated: October 23, 2025

    Water quality sensor data are logged by YSI EXO3 multiparameter sondes starting in the 2021 monitoring season. YSI’s KorEXO software is used to read and graph raw (BIN format) data files. A season cumulative raw data file is uploaded from the sonde during each monthly maintenance visit. The FQ_E deliverable includes all BIN files from all monthly visits from all monitoring sites in the sampling year, zipped into a single archive file. No corrections or quality control are applied at this stage. Sondes log data cumulatively during the season and are not erased, thus typically only the final file for each site is of interest; all other BIN files are retained in event of data or sensor loss. The details of FQ_E are in SEAN protocol package FQ-2022.1, SOP 5.
