Shark tracking

By keeping the numbers of other animals in check, their actions have a cascading effect down the food chain that helps keep both predators and those they prey upon in check, even in the face of climate change.

But the road to the marriage of science, data and technology has been a long one. Modern tags collect speed, depth and temperature data and send them via radio waves to satellites. To get around this, some tags pop off the animal after 30 to 90 days and float to the surface, where they transmit their data over satellite in one big chunk.

Shark Net relies on a tag that uses sound waves to transmit its data. Similar to how FasTrak communicates with toll booths at Bay Area bridges, an acoustic tag emits an individual high-frequency sound that is picked up by receivers floating nearby.

But the latest generation of acoustic receiver buoys are now able to transmit their data via satellite. The buoys dangle an underwater hydrophone that listens for the acoustic tags.
