The red icon indicates an alert. Alerts are issued when a white shark sighting is confirmed close to a public beach. A notification goes out with each alert.

The blue shark fin icon indicates a confirmed white shark sighting. These icons may appear on the app in real-time or there may be a delay based on vetting info.

The orange shark fin icon indicates an unconfirmed white shark sighting. This icon is used when a public report has been vetted but evidence is inconclusive.

The yellow icon indicates a receiver that detects white sharks tagged with acoustic tags and transmits the data in real-time. A daily summary of tagged sharks detected can be accessed by clicking on the icon.

The purple icon indicates a real-time detection of a shark tagged with acoustic tag that is less than an hour old. A daily summary of tagged sharks detected can be accessed by clicking on the icon.

The orange icon indicates detections of sharks tagged with acoustic transmitters. This information is not real-time. The data are uploaded to the app at the end of the season, providing a recap of activity at the location of specific receivers, which detect, record, and archive tag transmissions.

The green icon indicates SPOT tagged shark locations. This information is reported in real-time when the shark’s dorsal fin breaks the surface, and the tag transmits to overhead satellites. Note that the precision of the position estimates varies depending on the time at the surface and number of detecting satellites. Error around the estimates can range on the order of 50 ft to 50 miles.
