2026-10-11T19:24Z stage3 pressure interpolated (pressure_qc=8) — near-neighbour from aquadopp 400118 (Δhab=1.0m, static offset=+1.0 dbar) | QARTOD gross-range+spike: conductivity_qc=[good=19635]
pressure_qc=[good=0, suspect=512, bad=4, interp=19119]
salinity_qc=[good=19119, suspect=512, bad=4]
temperature_qc=[good=19635]

(3) Time series (full deployment)

line = data; × = suspect; × = bad; + = interpolated.

(4) Start & end windows — first / last 6 h

Left panel = first 7 h (1 h lead-in + 6 h of record) | Right panel = last 7 h (6 h of record + 1 h tail). ││ orange dashed = auto-detected (pressure-based) suggested deploy/recover time • ││ green dashed = YAML deployment_time / recovery_time • ││ grey = stage 1 raw record (same variable, same units).

Reading the grey background: where the raw stage 1 record is available and uses the same physical units as the stage 2/3 data, it is shown in light grey so you can visually verify that the chosen deployment window captures the in-water period. Cases where grey may be absent:

Sensors without their own pressure (e.g. a microCAT that relies on interpolated pressure from a nearby instrument) — interpolated pressure is only added at stage 3, so stage 1 has no pressure variable and no grey trace appears.
Velocity in beam or XYZ coordinates — if an Aquadopp or ADCP was configured to record in BEAM or XYZ mode, the stage 1 file contains beam/XYZ velocity variables while stage 3 stores ENU velocities; the variable names differ so no grey velocity trace is shown.
Conductivity — raw conductivity units sometimes differ between stage 1 and stage 3 (e.g. mS/cm vs S/m) and the grey trace is suppressed automatically to avoid a misleading scale mismatch.

If the orange vline is absent from the right-hand panel, no pressure-based recovery transition was detected in the final 25 % of the stage 1 record — the suggested recovery time equals the last raw sample. Check the timing table in the mooring summary report for the suggested UTC time.

(5) T-S diagram

Coloured by pressure (or sample index). × = suspect | × = bad (QC flags).

(6) Data value distributions

Orange dashed = suspect threshold | Red dotted = fail threshold (gross-range QC). Histogram shows non-bad data only; bad-flagged count noted in red.
