Karl Huggins has been the Director of the Catalina Hyperbaric Chamber Facility at the USC Wrigley Marine Science Center since 1992. He is noted for his work in decompression theory and models, which resulted in the Michigan Sea Grant (HUGI) tables and his participation in the development of the EDGE dive computer. Karl is the 1990 recipient of the Leonard Greenstone Diving Safety Award, the DAN/Rolex Diver of the Year for 1993, the 2004 Conrad Limbaugh Memorial Award for Scientific Diving Leadership and the 2008 California Scuba Service Award. And he puts up with Ken Kurtis for much of the year as they jointly shepherd the annual Chamber Day fundraiser.

WHAT YOU DON'T KNOW ABOUT YOUR DIVE COMPUTER CAN KILL YOU
You've heard the saying, "What you don't know can't hurt you." But that's NOT the case when it comes to dive computers. And few people know the intricacies of these digital information devices better than Karl Huggins. And it turns out that there ARE ways in which you can use a computer that while you may feel you're being safe, can actually put you in great danger. In this talk, Karl will outline some of those issues as well as just give some general advice about how to safely use a dive computer.

RETURN TO DIVING AFTER BEING INFECTED WITH COVID
Just because you - finally - tested negative after a bout with COVID doesn't necessarily mean you're ready to go back in the water. Charlotte has been at the forefront of medical research and studies of divers post-COVID, has helped develop protocols for when to return to diving that have been adopted by the Undersea Hyperbaric Medical Society, D.A.N., and the major training agencies. In this talk, she'll give an overview of what you need to be aware of as well as emphasize some of the risks of getting back underwater too soon, before your body is truly ready.

Steve Wertz is a Senior Environmental Scientist with the California Department of Fish and Wildlife (CDFW). Since 1991, he has served CDFW on variety of marine research and management projects. In 2008, Steve became involved in the design and implementation of California’s globally recognized network of marine protected areas (MPAs). Designed using a scientifically guided, stakeholder-driven approach, the MPA Network consists of 124 individual MPAs and 14 special closures that encompass approximately 16% of California’s jurisdictional waters, with 9% in no-take MPAs. As California approaches the 10-year anniversary of network completion, Steve and his amazing crew are preparing the first comprehensive review of the MPA Management Program and progress of the MPA Network towards meeting the ecosystem-focused goals of the Marine Life Protection Act.

MARNE PROTECTED AREAS UPDATE
One of the requirements in creating the network of MPAs was that they be adaptively managed. This means that periodically, CDFW and the various stakeholders would review the individual MPAs to see if they're working as intended and makes decisions about how to change that one way or the other to better fulfill the requirements of the Marine Life Protection Act. The first review was completed at the end of 2022 and Steve will update you on what changes and adaptations were deemed necessary moving forward.

TAKE BETTER PICTURES - IF SAM CAN DO IT, WHY NOT YOU?
Everyone who has ever held a camera in their hand wants to take better pictures than they currently do. And for those who are on that quest to be the next underwater Ansel Adams, Doug & Lorenza can help point you there. In this talk, they'll go through some of the basics and will share with you how they got their son, Sam, interested and involved in underwater photography.
