A Hole in My Heart

I HAVE BEEN A CERTIFIED DIVER since 1986 and have logged hundreds of recreational and technical dives. Since 2014 I have primarily been doing technical rebreather diving with a close group of experienced rebreather divers from Northern California.

Building Better Balance

DIVING TAKES PLACE in an environment that is dynamic both in and out of the water. Challenging and changing situations can happen even while traveling to a dive site. Balance exercises can help improve your ability to maintain or regain stability on a rocking boat. Wearing scuba gear changes your weight distribution and center of […]

Short but Beautiful Lives

MY FELLOW DIVERS WERE ECSTATIC AFTER A TWILIGHT DIVE on the Okinawa wreck near Pompano, Florida, in early June 2019. I was shooting wide angle and hadn’t paid much attention to small creatures during the dive, but they had found the holy grail for macro photographers: nudibranchs — in this case, regal sea goddesses (Felimare […]

More Than a Sore Shoulder

I REMEMBER SITTING AT MY COMPUTER while thinking about all the ibuprofen I had been popping for the past 18 hours and wondering why I still had the dull, aching pain in my shoulder. Could this be more than soreness from carrying gear back and forth from our shore entry point or exertion from a […]
