Description
Return deficit = suppliedSaturation-measured and saturationFraction = measured/suppliedSaturation.
Environmental measurements can require background subtraction, recovery correction, calibration or a common reference basis. Corrected values can be signed; a numerical correction is separate from detection, analytical validity and health interpretation.
Return deficit = suppliedSaturation-measured and saturationFraction = measured/suppliedSaturation.
When to use this tool
Use Dissolved Oxygen Saturation Deficit Term when checking a supplied measurement correction, comparison or calibration term.
How to use the tool and how it works
- Enter measured, suppliedSaturation. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read deficit, saturationFraction. Use the output convention below.
Require positive suppliedSaturation and nonnegative measured. Return deficit = suppliedSaturation-measured and saturationFraction = measured/suppliedSaturation. Use the same dissolved-oxygen concentration unit; a fraction above one indicates supersaturation relative to the supplied reference.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| measured | Measured | Required. Finite number; minimum 0. |
| suppliedSaturation | Supplied Saturation | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| deficit | Deficit | Required. Finite number. |
| saturationFraction | Saturation Fraction | Required. Finite number. |

}Limitations and assumptions
- Temperature, pressure, salinity and the saturation model are not computed. A negative deficit is retained and does not independently determine ecological condition or water safety.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use the relevant analytical method, quality-control records and uncertainty model before classifying a corrected measurement.
