Guadalupe Island ’12

Project type: Expedition
Dates: October 18-26, 2012
Location: Guadalupe Island, Mexico
Base: Liveaboard
Project target: placing acoustic tags on Great white sharks (Carcharodon carcharias), particularly large pregnant females
Lead scientist: Dr. Edgar Mauricio Hoyos Padilla
Tagging team: William Winram & Fred Buyle
Participants: fourteen from age 21 to 70
Sea life: abundant

The main challenge of this tagging expedition is simply the great white sharks. Paying attention at all times and making eye contact with these apex predators is what is required. Knowledge of the behaviour of great white sharks is paramount to alleviate social hierarchy behaviours toward the divers.

Eleven great white sharks, mostly large pregnant females, were tagged over the course of 5 days on site.

Here is a tagging sequence:

Participants to this expedition were witness to science in action. They enjoyed evening talks on the boat given by Dr. Mauricio Hoyos about sharks, his research and the particulars of Guadalupe island. Many thanks to them as their coming together to support sharks conservation is what made this expedition possible.
