The Edge of Extinction

I WAS HOOKED THE FIRST TIME I saw a southern sea otter bobbing in the surf off the coast of California’s Big Sur. I didn’t know then that I would be as spellbound by these rare creatures decades later as I was at that very first sighting.

The Ocean Less Traveled

TALK TO ANY HUMAN UNDER THE AGE OF 13, and they have probably been asked, “What do you want to be when you grow up?” I was just 3 years old when I knew I wanted to be a veterinarian. Growing up on coasts — first Cape Cod, Massachusetts, and then Southeast Florida — I […]

Not in Denial

HAVING DONE THOUSANDS OF DIVES since I started in 1964, primarily off the coast of North Carolina, the shipwrecks and dive profiles there are familiar. Overall conditions couldn’t have been much better on this particular day — calm, clear seas with barely a current. We planned on two reverse profile decompression dives at an offshore […]

When History Seemingly Repeats Itself

IN 1983-84, REEFS THROUGHOUT THE CARIBBEAN, FLORIDA, AND BERMUDA experienced one of the greatest mass mortalities of a marine species ever recorded when an unknown waterborne pathogen killed more than 98 percent of the Diadema sea urchin population.1 In February of this year, divers in St. Thomas noticed many of the Diadema were suddenly no […]

Diving After Brain Surgery

I RECENTLY UNDERWENT BRAIN SURGERY. The surgery was successful, but now part of my skull has been replaced with mesh.
