Southeast Alaska I&M Network Water Quality Data Package (FQ_Q) for monitoring years 2010-2024 at Sitka National Historical Park

This data set is a comma-separated values (CSV) file containing continuous hourly water quality observations of the Indian River in Sitka National Historical Park for monitoring years 2010-2024. The core parameters collected are water temperature, dissolved oxygen, pH, and conductivity, obtained from multiparameter sondes during the ice-free season. Turbidity was added to the monitoring effort starting in 2023. Using the Aquarius Time-Series application, data have been quality controlled, graded against formal criteria specified in the protocol (SOP 7, Data Evaluation and Grading in Aquarius), drift corrected where appropriate, and certified for publication. The data set (CSV) and associated metadata are zipped into a site-specific archive (ZIP file), identified as the FQ_Q deliverable in the water quality protocol.
