AUGUST SPEAKER: A Deep Dive into Diving Fatalities
Dr. Craig nelson - science behind diving fatality investigations
Dr. Craig Nelson
This program offers a rare behind-the-scenes look at the science of diving fatality investigations and provides valuable knowledge for every diver committed to making the sport safer.
Join SFDI Wednesday, August 5 for an Extraordinary Evening with Dr. Craig Nelson.
What really happens when a diving fatality is investigated? When news of a diving accident spreads, online discussion forums quickly fill with rumors, speculation, and theories—but they rarely provide the facts.
Our club is honored to welcome Dr. Craig Nelson, a long-time diver and forensic pathologist in Raleigh, North Carolina. He will take us beyond the rumors and into the science behind diving fatality investigations.
In this presentation, Dr. Craig Nelson will explain how diving fatalities are investigated, how forensic pathologists determine the cause and contributing factors of a fatal dive, and how those findings are used to improve diver safety. Drawing on his unique background as both an accomplished diver and practicing forensic pathologist, he will share real-world insights into accident investigation, the role of the medical examiner, and how lessons learned from these tragedies contribute to safer diving through the work of Divers Alert Network (DAN).

Photographing some of the most challenging locations imaginable with the goal of bringing back images that inspire and show the history and beauty of these remote locations.

Jeff Lindsay
ABOUT JEFF LINDSAY
Growing up on the shores of the Great Lakes fostered a natural curiosity about the unexplored for Jeff Lindsay; learning to dive in 1990 led to a lifelong desire to visit and photograph the unknown and forgotten.
With an almost limitless number of shipwrecks nearby, a natural progression into technical diving was required for the deeper and more remote locations.
He’s been invited on numerous projects as team photographer around the world as well as being a keynote speaker at Diving Talks, Portugal and DivExpo, Antwerp.
His biggest thrill is still visiting a shipwreck or cave and capturing some small part of its essence in a photograph.
