The Expedition White Shark app for iPhone, iPad and iPod is the awesome product of the Marine Conservation Science Institute that lets you track white sharks as they swim in the sea from the palm of your hand. Every week can be shark week with this app that tracks the animals the Institute has tagged, and even gives a little bit of background information for each shark, which are all named.
The system uses a satellite orbiting earth that follows the movements of the shark when its dorsal fin is out of the water, meaning the shark needs to be at the surface. While some of this may cause errors, it's the price paid to get the data at the same time as the American institution. The Expedition White Shark app also features a game, so it really can be shark week every week.
