Illustrative programme entry. Still North and this programme are fictional. The dates demonstrate a native calendar; no real session, registration, or booking is offered.
Listen with provenance in mind: recording conditions, sampling effort, and the limits of turning a detected sound into a statement about animals.
One question, worked carefully
A hydrophone records pressure changes at a particular place, depth, and time. What becomes audible also depends on the instrument, gain, sample rate, environment, and listening conditions. This example session asks what needs to accompany a recording before a sound can support a useful claim.
How the session is structured
- Read the provenance of a public example before listening. Note the source, instrument, setting, duration, and any limits on reuse.
- Separate an annotation from an identification. Record what is heard, what is uncertain, and which further evidence would support a species claim.
- Compare effort rather than treating a gap in recordings as a quiet sea. Explain why detections are not automatically animal counts.
What you can take away
A listening and annotation worksheet with room for uncertainty and effort. No new recordings, spectrograms, or species detections are claimed by Still North. The resources page points to a worksheet that links to real public examples and keeps their provenance visible.
Prepare with a source
Read Missing observations are not zeroes, then explore the guides and worksheets. The programme is associated with the fictional work of Noor Rahman; their profile explains the perspective behind the topic.
This is an invitation to practise careful reading, not a report that an event took place. Follow the linked primary sources and keep their definitions, dates, and limitations with any claim you reuse.
