Record view Guided workflow view Full record

Guided view follows recorded workflow branches and preserves evidence from branches you later change. Full view and print always include every field.

1. Record control and purpose

One profile ID must link metadata, readings, QA, and interpretation without overwriting the original sequence.

2. Station, time, and conditions

Record actual depths and a complete time reference. Do not assume fixed one-meter intervals.

3. Instrument and pre/post QA

Keep the instrument identity, settings, standards, acceptance criteria, and corrective actions with the readings.

4. Profile readings

One line per observed sequence. Include as-collected and canonical values, preserve replicate depths, and flag rather than erase anomalies.

Core record

5. Closeout and bounded interpretation

A descriptive layer or gradient does not establish cause, safety, internal loading, or treatment success.
