I shouted with euphoric joy through my regulator, 20 feet underwater. I can only imagine how wide my eyes were. It must have been difficult to discern between an expression of delighted surprise and a textbook example of wide-eyed diver panic. My eyes were transfixed on an old friend with a funny name whom I hadn’t laid eyes on in years. I had heard he was dead – or at least gravely ill. But there in front of me, larger than life, vibrant and embracing the sun, my friend was very much alive and healthy, clearly enjoying the good life in Cuba.
Several years earlier, I joined an expedition to explore a corner of the Gulf of Mexico I had only heard about from colleagues: The magnificent coral reef ecosystem of Veracruz, Mexico. Seated inside the DeepRover submersible with great anticipation for a vibrant reef that lay below me, I was lowered from the deck of a Mexican Navy ship into the warm blue waters below and radioed the ship that I was going to begin my descent.
