NEON Water Chemistry · Analyte Viewer unofficial

NEON's labs measure the chemistry of streams, rivers, and lakes across the country — hundreds of samples per site, not a handful. This app reads one aquatic site at a time and compares any two analytes over its full record. Built on the Surface Water Chemistry product (DP1.20093.001).

Tap a site on the map (coloured by the analyte you choose) to explore it, or pick one by name below. 34 aquatic sites , from desert streams to arctic lakes.

This is dense, honest water-chemistry data

You're looking at 196,856 water-chemistry samples from one NEON aquatic site, with hundreds of records per site rather than a handful. Pick a tab above, or jump straight to the relationship between two analytes.

How the stats stay honest: every statistic shows its sample size; correlations default to Spearman with an n ≥ 8 reliability flag; the seasonal view is a real STL decomposition of the monthly record, not a forecast; below-detection values are flagged, never hidden; and one per-analyte plausibility gate keeps a single artifact from driving any fit, the trend, the predictor, or the map's colour scale.

Regression
Fit statistics
OLS on date-paired samples. Correlation ≠ causation; repeated-measures p-values are optimistic.
Main analyte vs every other analyte
Show all analytes
Top 18 shown above (open Show all analytes for the full table). Teal = reliable, grey = under 8 paired samples or > 25% below detection. Computed on co-sampled dates only; screening many analytes at once inflates chance findings, so treat them as hypothesis-generating, not confirmatory. Toggle BH q for Benjamini-Hochberg false-discovery-adjusted p-values.
Monthly climatology
Seasonal-trend decomposition (STL)
Descriptive of the real monthly record, not a calibrated forecast. Needs ≥ 24 months.
Estimate the main analyte
Prediction
glm on the 3 best-correlated analytes; cross-validated RMSE shown. Interpolation aid, not a sensor.
Same analyte, two sites
vs
The main analyte at the selected site vs a second site, over the same date window.
Search the network

Find sites by their water chemistry across the whole network, then jump to one. Values are each site's average over its full bundled record, computed the same way as the map (implausible extremes excluded). This ranks sites by a within-site index, it is not an absolute ranking, and below-detection samples are kept in the count and flagged, not dropped.

Click a site code, or its Go to site button, to load it from the bundle and open it on the map. n = plausibility-gated samples at that site; below-DL = share reported below the analytical detection limit.
