Submarine Eruption Depth Suppression Checker
Audit independently established gas/ambient pressure contrasts against caller matched suppression-model evidence bands, no eruption-depth safety guarantee or hydrostatic-only forecast. Unknown criterion indices distinguish zero placeholders from known zero margins. Caller independently establishes units, regime, calibration and applicability; this does not establish design-code compliance, authenticity, operational safety, treatment efficacy or a validated forecast.
Description
Water depth alone does not establish whether a submarine eruption is suppressed.
Water depth alone does not establish whether a submarine eruption is suppressed.1
This tool compares independently established gas and ambient pressure contrasts with your matched model bands, while retaining unknown criteria.
When to use Submarine Eruption Depth Suppression Checker
Use this tool when you need to identify observed values outside a supplied band and keep unknown evidence visible. Prepare matched observations and independently established site, specimen, units, datum, and calibration context.
How to use Submarine Eruption Depth Suppression Checker and understand its results
- Prepare matched observations and independently established site, specimen, units, datum, and calibration context.
- Enter observedSubmarineObservedGasPressureContrastPa, callerVerifiedSubmarineObservedGasPressureContrastPaLower, callerVerifiedSubmarineObservedGasPressureContrastPaUpper, knownSubmarineObservedGasPressureContrastPaCriterionFlags, following the field table and rules below, then run the tool.
- Read signedKnownBandMargins, knownReviewIndices, unknownCriterionIndices. Use the output meanings below to interpret units, signs, flags, and any nested result fields.
- Correct reported input issues and run again. For a successful result, check the stated evidence coverage and assumptions before using it in your review.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| observedSubmarineObservedGasPressureContrastPa | Observed submarine observed gas pressure contrast pa | list of number | Required |
| callerVerifiedSubmarineObservedGasPressureContrastPaLower | Caller verified submarine observed gas pressure contrast pa lower | list of number | Required |
| callerVerifiedSubmarineObservedGasPressureContrastPaUpper | Caller verified submarine observed gas pressure contrast pa upper | list of number | Required |
| knownSubmarineObservedGasPressureContrastPaCriterionFlags | Known submarine observed gas pressure contrast pa criterion flags | list of number | Required |
Use aligned nonempty observation, lower-bound, upper-bound, and known-flag lists. Flags are binary zero or one and every lower bound must be at most its upper bound, including unknown entries. For known observations, return the smaller signed distance to the two bounds. A positive margin is inside the band, zero is on a boundary, and a negative margin is outside. Return zero-based review indices only for known values strictly outside the band. Unknown entries receive zero margin placeholders and separate unknown indices; these zeros do not confirm compliance.
margin_i=known_i?min(observed_i−lower_i,upper_i−observed_i):0 Symbols follow the input and output meanings and the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| signedKnownBandMargins | Signed known band margins | list of number |
| knownReviewIndices | Known review indices | list of number |
| unknownCriterionIndices | Unknown criterion indices | list of number |

}Limitations and assumptions
The bands and applicability are supplied by the user. Unknown evidence is not a passing test, and the tool does not validate the source or the suitability of a criterion.
Missing required fields, unknown fields, wrong types, and violated calculation rules are input issues. Numeric values must be finite; nonfinite results are rejected. Evidence arrays must be dense, with no missing cells. Numeric observation lists allow at most 10,000 entries, subject to any smaller bounds stated above.

This checker reviews your positive evidence requirements and preserves classes that remain possible when observations are missing. For a complementary step, use Hydrothermal Boiling Point Depth Curve Calculator: Hydrothermal boiling temperature depends on the pressure and fluid branch being used. This tool reads a supplied pressure–temperature calibration after composition, pressure, and datum have been resolved independently.
