Technical Scuba Diving
To bring you this important announcement... Just in case you have been wondering what I have been up to and why there has been a dearth of postings in the past couple months. There will be no diving for the foreseeable future. I think I've had 3 days of diving in the past 70+ days. [...]
I am very honored to be awarded the Winner in the Wreck Category for the 2023 Underwater Photographer of the Year (UPY) contest. The "photo" that won is a screen capture of the final photogrammetry model I built of the F8F-1 Bearcat that sits 230 feet deep off Point Loma, California. To date, there have [...]
Background I have been trying for quite some time to find a good solution for listening to music underwater while on deco. It can get very boring and I love music so it seems like a good idea. However, it hasn't been easy to find a solution which meets all my needs. In the previous [...]
Background We have had absolutely horrible conditions since Christmas. Between the large swells, wind, rain and resulting run-off, diving has been non-existintent for weeks. I snuck in a couple dives to teach a photogrammetry class, but that is about it until this week. Dive 1 - 275' Target (South of Pt Loma) Tyler found a [...]
As the saying goes "I"m hard to shop for." This Christmas, my wife was creative and very thoughtful when she arranged for a Gyotaku art class -- with a world class artist who happens to live very close to us. I've always really enjoyed the look of Gyotaku art and admired the prints during my [...]
Background I held my first photogrammetry class between Friday, Jan 20th through Sunday, Jan 22nd. This the first time I held the workshop and the results were very good given the conditions we had for the dive day on Saturday, Jan 21st. After a day of lecture and building a model on land, we dove [...]
I recently gave a presentation on the Zoom Seekers series. It was focussed on Southern California Wrecks and coves some of the tools we use to find and identify new wrecks. It provides details on how photogrammetry can be used for multiple purposes in wreck identification. I hope this presentation provides a peek into what [...]
Intro The adventure continues! Here is a snapshot of the project status after Dive #7 and before this dive. Obviously, still missing a few areas on the starboard amidships to hull area. After the results from dive #7 (Cave Line & Cookies), I had one more possible way to align photos for the stern section. [...]
Intro I published a Top 10 Diving Recap in 2020 and then again in 2021. This year I am making it a "Top 10 Dives and Projects" list since quite a bit of my diving this year has been working on more longer-term projects that involve multiple dives on the same wreck. It has been [...]
Intro I first dove the Bearcat back in June 2022 and it is an amazing wreck. It is very rare to find an almost completely intact single engine airplane wreck. When I first dove it, I was concentrating on getting photos for identification and documentation and not for building a photogrammetry model. I was alone [...]
