Alert Levels

AI1SAD estimates environmental and surveillance-relevant shark encounter conditions. It does not predict individual attacks or guarantee safety outcomes.

Alert levels are operational labels for review, monitoring, and communication. They are not attack-probability categories.

Levels

advisory

Conditions deserve awareness, but the signal is limited, uncertain, or event-specific.

watch

Conditions support increased attention by lifeguards, beach managers, drone teams, researchers, or API users.

warning

Environmental/live-condition signals are elevated enough to support active operational review.

urgent_surveillance

Search-zone priority is high enough that drone, lookout, or patrol teams should consider prioritizing the area even if the general environmental warning is low.

Alert Types

  • general_warning: environmental/live-condition warning score is elevated above baseline.
  • surveillance_priority: search-zone priority is high for safety teams.
  • activity_hazard: human activity context increases encounter hazard.
  • biological_event: carcass, prey, stranding, fish kill, or related biological signal is active.
  • sighting_cluster: multiple recent public sightings are active near the area.
  • post_incident_surveillance: a recent interaction supports time-limited post-incident monitoring.

Confidence

Confidence is lowered when data sources are stale, missing, conflicting, or low quality. Alerts should expire rather than silently assume old data is still current.
