OCEAN HEALTH
Nitrogen Load (NIT)
Dissolved-nitrogen enrichment in monitored water — the fuel behind algal blooms and the hypoxia that follows. The upstream cause the dissolved-oxygen alarm only reports after the fact.
Threshold Bands
| Band | Range | State |
|---|---|---|
| Clean | < 0.3 | OK |
| Enriched | 0.3–1.0 | WARN |
| Eutrophic | > 1.0 | CRIT |
Formula
Dissolved inorganic nitrogen (nitrate + nitrite + ammonium) from in-situ analyser and lab panel.
