Tracking great white sharks with a drone via Iphone

Imagine floating on the empty blue Pacific Ocean, nothing but water in every direction, sunrise to sunset. Yet under the surface swim thousands of great white sharks.

That’s not a bad dream — it’s actually what happens around this time of year several thousand miles off the coast of Baja California, about halfway to Hawaii. The king predators congregate in a huge area of the ocean affectionately named the White Shark Cafe.

But why the big sharks stack up in this remote spot remains a mystery. The area is also known as “the desert of the ocean” and so far Sal Jorgensen, a research scientist at the Monterey Bay Aquarium, says there is little observable life to sustain a food chain. The sharks also assume bizarre behavior, sometimes diving thousands of feet at intervals as short as ten minutes apart. The reason white sharks travel halfway across the ocean appears to be somewhere between eating and meeting a mate, hence the idea of a “cafe” — but only better research can determine whether it’s more “restaurant” or “motel.”
