Shark Café camera

Great White Sharks have a yearly migration from the coast of California to Hawaii and back. On the way to Hawaii, it has been observed that the Great Whites will ‘hang out’ in a region about halfway for several weeks-this region has been called the Shark Cafe. They display interesting behavior at the Shark Cafe where they rapidly swim up and down between the surface and about 250 meters with occasional pauses at various depths. Dr. Sal Jorgensen, shark researcher at the Monterey Bay Aquarium, proposed building a video capable animal tag to try and answer the question of what they are doing-mating or feeding or ?Shark Activity Map

Event Triggered Video

Using sensor data, turn on video camera to capture specific behavior

Shark behavior of interest during Great White Shark oscillating

dive behavior at the Café.

Science+Engineering approach to Event Triggered Video:

-Scientist processes archived shark tag data, writes algorithm in Matlab that detects behavior patterns of interest in the data.-

-Engineer re-implements that algorithm to be embedded in the SharkCafeCam tag for ‘event triggered’ video recording
