In September 2008 we were part of an expedition on board the DEEPSEE submersible to discover the deep sea life of Guadalupe Island (www.jatay.org). Several species never seen in the island (rat fishes, skates, electric rays, nudibranchs, octopuses, squat lobsters, and several different species of fishes) were witnessed by the submersible scientific staff. Also we recorded diverse behaviors of great white sharks at different depths and potential preys for this species that were unknown for the island.
During the last season the scientific staff tagged several white sharks with coded transmitters and set underwater receivers (VR 2) in specific locations around the island known for their importance as aggregation sites for juveniles and adults. With these underwater monitors the movements of the sharks will be recorded on a year basis helping to understand the nature of their presence at the island.
In August 2009, Greg Marshal from National Geographic, will help us to set a crittercams in white sharks in Guadalupe Island. Crittercam is a research tool designed to be worn by wild animals. It combines video and audio recording with collection of environmental data such as depth, temperature, and acceleration. Safely worn by wildlife, crittercam gives us rare views of the private lives of animals. By allowing us this animal's-eye view, crittercams help to solve scientific mysteries. In Guadalupe Island we will set critercams in juveniles and adult White sharks in order to discover the differences in their habitat use while they are around the island.
Thanks to the gracious support of the WWF-Telcel alliance, we will release a new book on the great white shark: The great white shark, amuakua of the oceans". It will be available for sale later in the year.
The book has excellent illustrations, paintings, and photographs. But more importantly, this book does a good job of summarizing aspects of the biology, ecology, and behavior of the White shark in Guadalupe Island.
