Southeast Alaska Network water quality monitoring SOP 2: Data Evaluation and Grading, version 2.0
Sergeant CJ, Johnson W, Moynahan B, Nagorski S. 2013. Southeast Alaska Network water quality monitoring SOP 2: Data Evaluation and Grading, version 2.0. NPS Southeast Alaska I&M Network, Juneau, Alaska.
This reference is for standard operating procedure (SOP) 2 from the FQ-2013.1 protocol package, in effect between 2010 – 2020. After raw measurements are collected in the field, water quality data are evaluated by the Park Lead and Project Leader to ensure accurate transfer from the sonde to the handheld display to the computer (SOP 3). After this initial review, erroneous values are flagged and remaining data are quality-graded (Poor/Fair/Good/Excellent). This SOP defines data outliers and prescribes grading criteria and methods. Generally, USGS guidelines and standard procedures (Wagner et al. 2006) are followed, with some modifications required by logistical constraints.
