Technical Scuba Diving
After publishing our story about the Sea King, we were contacted by many friends and family of Gus Herrmann who had died in the helicopter crash on that fateful September day in 1968. Tyler, Lora, and I spent yesterday on the Marissa visiting the site of the Sea King helicopter crash with a special group [...]
Background More than any other photogrammetry project, getting a complete and good model of the stern section of the UB-88 has vexed me. It has been very frustrating and my first attempt failed. Below is a screenshot of the model I made in November 2020 that was only able to resolve the starboard side: Starboard [...]
Background Tyler and I first dove the PBM Mariner a couple weeks ago. During that dive, we had very limited visibility so taking pictures was challenging and I built a photogrammetry model based on those photos. It came out relatively well but was incomplete and I didn't get all of the pictures needed to "link [...]
Background I had first heard about a PBM Mariner wing section from Steve Lawson last year. Since then, Tyler Stalter and I had spent quite a few days and dives trying to find the elusive wing and ended up empty handed on all of those dives. Tyler had been at it a lot longer trying [...]
Diving and taking photos at the bell on the Typo wreck 180' deep in 40F water (Photo Credit: Mel Clark) Background Quite a few people have asked about the equipment needed to safely dive and photograph wrecks that are 200 feet deep in 38-40F water at the bottom and with reasonably long (75-90 minute) decompression [...]
Background During my ill-fated trip to Bikini Atoll, we ended up diving quite a few WW II airplanes that had been dumped near Kwajalein Atoll. Tyler and I had seen some ROV footage of something similar off Point Loma and we decided to charter the Marissa with Lora and Chris to investigate and perform a [...]
Background In the ongoing project of building a complete, detailed photogrammetry model of the UB-88, Drew Wilson and I went back with Ray Arntz on the Sundiver for two more dives. On my previous dive, I completed the port and starboard hulls to complete the front half of the model. My goal on these two [...]
Background It has been a long time since I dove the UB-88 and I had definitely missed it. I think it is one of the coolest wrecks in Southern California. My previous dive on the UB88 was December 10, 2020 and the visibility was soooo bad at depth that Justin and I couldn't even find [...]
Background I dived the Cape Charles a few months in July 2021 on the Marissa with Lora & Chris. I had dived the wreck once before but it was one of my early tech dives here in SoCal so I only took a GoPro and didn't get any photos. I had a chance to return [...]
The Tale of the Tail Code This is a tale of hope, frustration, and persistence during our dives to find and identify a new helicopter wreck off Imperial Beach, California. The final identification was the result of a LOT of research and a somewhat obfuscated tail code that we uncovered on the second dive. We [...]
