EDUCATION

SOCIALIZATION
Meeting begins at 5:30 at the Elks Lodge
I have been a diver since 1965. I learned to dive in the Channel Islands off the California coast near Santa Barbara and Ventura. After a long layoff for work and family, I became a Dive Master in the late 90’s and an instructor at the start of the new Millennium and have been an Instructor since then. I have taken and taught many Rescue classes and CPR/First Aid classes as part of my instructor duties. I became a Dan, HSI and American Heart instructor before COVID and started teaching for the Red Cross in 2018.
Crazy, right?
I am now focusing on teaching American Red Cross classes and training instructors for ARC.
This program will focus on what to do once the injured diver is out of the water, unresponsive and not breathing. Something you never want to have to use, but it is always better to be prepared.
Our MISSION is to bring together diving enthusiasts to promote marine and dive
education, conservation and community.

Tym Catterson
Tym grew up in the central Oregon high desert town called Sisters. At first the population was about 500 counting the cats and dogs, but that has changed. In this desert he wanted to be an Oceanographer, probably from watching all those episodes of “Sea Hunt” and “Jacques Cousteau”. Go figure!
Years later when living Hawaii I did manage to get into ocean research but is was quite different than he expected. His goal of being a scientist didn't pan out but hhis trade skills as a machinist did. He started out working for a small engineering company developing a very deep diving remote operated vehicle (ROV). This later lead to another job with the University of Hawaii's manned submersibles program aptly, named HURL. For many years HURL sailed the Hawaiian waters counting fish, retreiving military things that got lost overboard, and then to diving into undersea volcanos.
He later went to New Zealand with a submersible project in Milford Sound south island, then to working with James Cameron filming “Aliens of the Deep”. After this he did several other undersea documentaries that needed sub pilots and technicians, (think NHK/Discovery, Sharks, and Search of the Giant Squid).
In 2023 he was involved with the Ocean Gate expeditions when it ended in tragedy. He was contracted to be safety diver and LRT operator, After the implosion he participated in the search, and after the remains were found he stayed on site to join Pelagic Research Services to help with recovery. A very sad time.
Now, he designs and builds science packages sampling devices for various operations. He was honored to share his experiences with such a harsh yet amazingly wonderful and place.
Cheers,

“Scuba Storyteller: How I Turned Four Decades of Dive Logs into a Book” By Gil Zeimer
I’ve been diving for 40 years and publishing stories about it for more than 30. Along the way, He amassed more than 300 scuba articles, blogs, and newsletters that have appeared in over 25 magazines and websites, with 65 of his favorites in his first book. The presentation show how one can turn a dive log entry into stories––both for personal blogs and for possible publication as articles or even as a book.
He share his favorite story titles, such as “Warm Memories of Hypothermia”, “Waterlogged Proposals”, “Low Anxiety: Getting Narked in Belize’s Great Blue Hole”, “The Sun Also Burns”, “Maui March Madness––Honeymooning With Humpbacks”, “Jaws at 50: This Shark Still Has Legs”, and “My Dive Buddy Wears Diapers”––and how he got them published in various magazines and websites.

The heart of any organization is its purpose for existing. Promoting education is a major driving force in our club. Ocean education is important. Captain Jacques Cousteau said "that people protect what they love". While Captain Cousteau's comment was absolutely true, people have a difficult time loving things they do not know about. This is why our focus on education is incredibly important. The club engages in providing educational opportunities for students, community groups and club members.
In addition to educational outreach and internal presentations by club members, we actively provide financial support to conservation groups and businesses that engage in educational activities and projects aligned with our mission. Links to these activities and projects are provided above. Please take some time to virtually visit the programs we support. If you know of another resource, project or program worth our attention, let us know at education@desertdolphins.org
The Desert Dolphins Scuba Diving Club has a long tradition of providing ocean education presentations and activities in Tucson-area schools. Club members have presented and provided workshops in classrooms and during science night types of activities.
