dune2_1_2026Summary

(1) Processing pipeline

Raw = file present in raw directory • Read = format check passed • Stage 1–3 = processed NetCDF files exist • Stack = mooring-level _stack.nc • Grid = pressure-gridded _grid.nc

Instruments marked skip: true in the YAML are excluded from all processing and are shown with a skipped note in the Note column. Stack and Grid pills are grey for any instrument that did not reach Stage 3. See the instrument summary for skip reasons where given.

(2) Instrument summary

Variables and record length are read from stage 3 files where available, otherwise stage 2. The P badge is shown as present whether pressure was directly measured or interpolated from neighbouring instruments — see the QC flag summary to distinguish. Instruments marked skip: true are listed with the skip reason where provided.

Recommended pressure range for oceanarray process --stage grid, derived from the min/max pressure across all instruments (rounded outward to the nearest 20 dbar):

--pmin 80 --pmax 820

(3) Deployment timing

Stage 1 and Sugg. (raw) columns are in the raw instrument clock (uncorrected). Sugg. UTC columns apply the constant clock offset (and drift, for the end) and are safe to paste into the YAML deployment_time / recovery_time fields. Suggested UTC cells are highlighted amber when the pressure-derived suggested time differs from the YAML time by more than 2 Δt (indicating a sinking/rising transient was detected). The Stage 1 last cell is highlighted orange when the raw record ended more than 2 Δt before the YAML recovery time (instrument may have stopped early). Serial numbers link to the per-instrument report; the 6 h link jumps directly to the start/end window plots.

Spot-check recommended: open the 6 h start/end window plots for each instrument (click 6 h) and visually confirm that the orange suggested line (or green YAML line if they match) sits at a plausible transition in the pressure (or temperature) record before updating the YAML times.

(4) Clock corrections

Positive drift/offset = instrument was slow (behind UTC); correction shifts times later. Negative = instrument was fast (ahead of UTC); correction shifts times earlier.

Clock alignment check. Overlaid temperature records zoomed to the first and last 30 minutes of the deployment. If instrument clocks are misaligned the temperature curves will appear shifted in time. Data are from stage 3 (or stage 2 if stage 3 is not yet available). Instruments with no temperature data are omitted.

Nominal HAB (x) vs. measured pressure (y). The dashed line shows expected pressure (water depth − HAB). Instruments below the line were knocked down. Interpolated pressure (QC flag 8) excluded.

IQR of pressure anomaly (measured − nominal) per instrument. Positive = deeper than design depth. Green < 100 dbar, yellow 100–200, amber 200–300, red > 300 dbar.

Estimated horizontal displacement (m) vs. measured pressure. Left: scatter per instrument; right: normalised 2-D density across all instruments. Displacement derived from the rigid-pendulum approximation: x = √(hab_nom² − hab_meas²).
