Currently displayed models were developed using data from YSI 6-series sonde. Equipment was upgraded to YSI EXO sonde on 8/17/20. This will introduce additional uncertainty that may not be reflected in the computed confidence limits.
The data used to produce this plot are provisional and have not been reviewed or edited. They may be subject to change.
Data pulled 11-21-24 16:03.
The chart is interactive: you can mouse over to highlight individual values. You can click and drag to zoom. Double-clicking will zoom you back out. Shift-drag will pan.
Notes
The statistical (regression) model used to compute total nitrogen is site specific. Gaps in data occur either when data are not available or their values are outside of the range for the regression model. Users should consider these factors, as well as uncertainty associated with regression-model computed data, when applying this information to specific issues.
