Reading these numbers
- Single source of truth. Deployment figures come only from AusMT per-station runs records. The instrument registry’s field-survey DOIs (coverage windows, component lists) are deliberately not used for deployment accounting — they remain as PID-graph links.
- Coverage grows as runs are populated. — Every figure on this page grows as AusMT metadata is populated — the register is a floor, not a ceiling.
- Hours measure acquisition, not campaign commitment. An instrument’s recording-hours exclude transport, setup and idle time between stations, so these are conservative utilisation figures.
- Scope: AuScope-funded instruments (DataCite fundingReferences). Instruments without an AuScope funding tag are excluded from all totals here.
- Electrodes are invisible. Electric-channel hardware carries no identifiers in the source metadata, so only recorders and magnetic coils are countable.
- Whole models still wait on runs metadata. An instrument whose surveys have no populated runs block does not appear here at all — a metadata backlog, not idle hardware. Each survey enters the register automatically once populated.
Sources. Run records: ausmt.auscope.org.au /data/products/<survey>/<station>/station.json — snapshot fetched — (feed ausmt-data.json, regenerated weekly by src/ausmt-inventory.js; upstream build —). Fleet scope: DataCite instrument registry, prefix 10.82388, AuScope-funded units via fundingReferences.
Method. One occupation = one instrument (recorder or coil) at one station for one run’s time_period. Recording-hours sum the acquisition windows; days are hours ÷ 24. Every figure is recomputed from the feed at page load — nothing on this page is hand-entered. Explore: Impact overview · Instrument Registry · AusMT Portal
