However, at night hoards of squid would swarm under the lights we even found a freshly killed giant squid ( Architeuthis sp). We saw very few seabirds and almost no pelagic fishes. First, I was able to determine that Great White Sharks in the SOFA are NOT feasting on seals, dolphin or porpoise…the SOFA was basically a huge zone with very little life at the surface.
The expedition raised as many questions as it answered. Chris Fischer and the National Geographic Channel made that expedition possible and some of the events are portrayed on two episodes of Expedition Great White. But what are the Great White’s eating in the middle of the ocean? If I had a dollar for every time I’ve been asked that question I would be taking my vacations in a private jet! But it’s a great question, one that inspired me to mount the very first expedition to the SOFA to visually characterize the SOFA habitat and creatures that live there. The SOFA is a huge area, so big that White Sharks probably rarely encounter one another while they are offshore. This is an area we have termed the Shared Offshore Foraging Area, or SOFA, because Great White Sharks from both Guadalupe Island and Central California travel the this area to feed. Adult White Sharks in the Eastern Pacific spend 6-16 months in the deep Pacific Ocean, halfway between the mainland and the Hawaiian Islands. When I recently heard rumors that a sperm whale calf had washed ashore on the shores of Montauk, and that this calf had a massive shark bite on it, I became very interested. The app displays a map with live tracking data for the sharks tagged with real-time tracking devices, so that users can follow these sharks at the same time as the research scientists! The Guadalupe Gallery shows images of all sharks in the Guadalupe Island photo-ID database and the photo gallery has photos and videos showing how the sharks were tagged.įor more information see The app, called Expedition White Shark, includes numerous features that let users learn more about these amazing animals, including the ability for users to track satellite-tagged great whites. The Marine Conservation Science Institute has launched an app focusing on great white sharks.
For more information see “Two-year migration of adult female white sharks ( Carcharodon carcharias) reveals widely separated nursery areas and conservation concerns” Amy and Kimel traveled into the Sea of Cortez while Annika and Tailscratch went to the Pacific coast of Baja. These sharks spent about 15 months in the middle of the Pacific ocean before traveling to the coast of Baja Mexico during the known pupping season. MCSI has published a new scientific paper that reveals the multi-year migratory patterns of four tagged female white sharks Amy, Kimel, Annika and Tailscratch.
