Isla Holbox is perhaps the best known commercial whale shark encounter sites on the planet. A surprising success story of commercial shark diving and growing site research and conservation.
With little known about these "gentle giants" a scientific expedition lead by Dr. Sylvia Earle's Deep Search Foundation chronicled it's time here from July 11th - 15th, 2009 in an in depth series of blog posts.
Great reading for those desk bound shark adventure seekers.
About Deep Search Foundation
Founded in 2008, Deep Search is dedicated to exploring and protecting Earth's ocean, the cornerstone of our planet’s life support system. More than 70% of Earth is covered by ocean, and 94% of our habitable space is in the seas. Yet, we have explored less than 5% of the ocean and protected only a fraction of 1%. These figures pale even further when one considers the deep sea.
