Data coverage

Where vShark knows little is as important as where it knows more. Missing coverage does not mean low risk.

Shark observation coverageNONE
SharkSmart WA / DPIRD detections are not machine-connected. No live tagged detections in vShark.
Ocean coverageMODERATE
Open-Meteo marine SST and wave height at a regional centroid — not a beach sensor.
Weather coverageMODERATE
Open-Meteo forecast weather at a regional centroid.
Ecology coverageLOW
No live prey, whale, seal or productivity feed. Seasonal notes are hypotheses or climatology.
Human exposure coverageLOW
Estimated from popularity class, weekday/weekend and swell. Not a head-count.
Sensor coverageNONE
No acoustic, camera, drone or eDNA adapters connected.
Historical coverageLOW
Incident reconstructions are added as frozen validation cases, not a complete history.
