Description
Calculate nominal filtered volume from supplied mean flow and sampling duration.
Ecological records need explicit sampling units, detection states, effort denominators, interval geometry and trait/abundance bases. Nondetection differs from absence, and shared sampling-unit labels do not alone diagnose pseudoreplication. A one-axis overlap or single weighted contribution is only a limited component of a broader ecological analysis.
Calculate nominal filtered volume from supplied mean flow and sampling duration.
When to use this tool
Use Aquatic Drift Sample Filtered Volume Term when you already have meanVolumeFlow, samplingDuration and need to calculate nominal filtered volume from supplied mean flow and sampling duration.
How to use the tool and how it works
- Enter meanVolumeFlow, samplingDuration. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read filteredVolume. Use the output convention below.
Require meanVolumeFlow and samplingDuration>=0; multiply them.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| meanVolumeFlow | Mean Volume Flow | Required. Finite number; minimum 0. |
| samplingDuration | Sampling Duration | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| filteredVolume | Filtered Volume | Required. Finite number. |

}Limitations and assumptions
- Flow must already be interval-mean volume/time with compatible duration. No clogging, effective filtration, sample recovery or actual net flow is modeled.
- 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
Review original survey records, sampling design, specimens and calibration definitions for an ecological conclusion. Use complete detection, population, community or process models as appropriate; local count rates and source labels do not infer unobserved states or ecological mechanisms.
