(1) QC — glidertest diagnostics
Profile number: No issues detected. Profile duration: 10 profiles have abnormal duration.
glidertest diagnostics — run on the fly, not written to the file. Thresholds are glidertest's own (hardcoded for the Baltic), shown so the verdict can be reproduced.
| Variable | Test | Suspect range / threshold | Fail range / threshold |
|---|---|---|---|
| TEMP | gross-range | [0, 30] | [-2.5, 40] (not applied) |
| TEMP | spike | |Δ| > 2.0 | |Δ| > 6.0 |
| TEMP | flat-line | flat ≥ 1 s (tol ±0.001) | flat ≥ 3 s (tol ±0.001) |
| TEMP | hysteresis | > 5% dive–climb error per depth bin | > 5 bins exceed |
| PSAL | gross-range | [5, 38] | [2, 41] (not applied) |
| PSAL | spike | |Δ| > 0.3 | |Δ| > 0.9 |
| PSAL | flat-line | flat ≥ 1 s (tol ±0.001) | flat ≥ 3 s (tol ±0.001) |
| PSAL | hysteresis | > 5% dive–climb error per depth bin | > 5 bins exceed |
Test × variable: flagged-sample counts (per-sample tests show a small dashed bar). Gross range applies the suspect span only — the fail span above is not yet evaluated. Hysteresis counts depth bins with >5% dive–climb error; a variable is flagged when more than 5 bins exceed it.
| Test | TEMP | PSAL |
|---|---|---|
| Gross range | clean | clean |
| Spike | clean | 6 susp 1 fail |
| Flat line | 79,711 fail | 77,856 fail |
| Hysteresis (mean) | 18/988 bins | 0/988 bins |
| Hysteresis (range) | 46/988 bins | 15/988 bins |
(2) Gross range (T–S)
Current gross-range limits (applied)
- TEMP — suspect [0, 30], fail [-2.5, 40]
- PSAL — suspect [5, 38], fail [2, 41]
Suggested gross-range limits (this deployment)
- TEMP — suspect [2.62, 7.1], fail [2.44, 7.28]
- PSAL — suspect [32.68, 35.27], fail [32.58, 35.37]
Each span is the central 99.9% of the finite values padded by 1% (suspect) and 5% (fail) of that span. Descriptive of this mission, not a physical range.
(3) QC — TEMP
Current limits (applied)
- TEMP flat line — suspect ≥ 1 s, fail ≥ 3 s (tol ±0.001)
Suggested limits (this deployment)
- TEMP flat line — suspect ≥ 20 s, fail ≥ 30 s
TEMP is sampled about every 10 s; a flat-line window needs to span a couple of its samples, so use suspect ≥ 2× and fail ≥ 3× that interval (a window shorter than the sampling flags every point). Descriptive of this mission, not a physical range.

(4) QC — PSAL
Current limits (applied)
- PSAL flat line — suspect ≥ 1 s, fail ≥ 3 s (tol ±0.001)
Suggested limits (this deployment)
- PSAL flat line — suspect ≥ 20 s, fail ≥ 30 s
PSAL is sampled about every 10 s; a flat-line window needs to span a couple of its samples, so use suspect ≥ 2× and fail ≥ 3× that interval (a window shorter than the sampling flags every point). Descriptive of this mission, not a physical range.
