Guggenheim has worked in Cuba for more than 20 years leading collaborative research and conservation efforts in Cuba focused on coral reef ecosystems. His 2022 book, The Remarkable Reefs of Cuba: Hopeful Stories from the Ocean Doctor, details his two decades of experiences in Cuba, working in collaboration with Cuban scientists to explore that country’s unique underwater ecosystems and to understand why the world has lost half of its coral reefs while they continue to thrive in Cuba.  As an ocean explorer, Guggenheim piloted the first manned submersible dive into the world’s two largest underwater canyons, which are located in Alaska’s Bering Sea.
