The Atlantic White Shark Conservancy Sharktivity App was developed in collaboration with the Massachusetts Division of Marine Fisheries, the Cape Cod National Seashore, and officials from Cape Cod and South Shore towns to raise awareness of the presence of white sharks off our coast.
The App sightings are fed by researchers, safety officials, and users that upload photos for confirmation. By enabling App users to report shark sightings and upload photos for confirmation, we are effectively crowd-sourcing critical data points on where sharks are spotted so as to reduce encounters and promote safety. Data from sharks with acoustic tags and Smart Position and Temperature Tags (SPOT) are also available on the App.
Our goal is to raise awareness and help facilitate the peaceful coexistence between humans and white sharks.
Please review the icon descriptions below and note that there is only one alert icon, denoted in RED.
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 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 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.
