Dr. Mark Legg is recognized as one of the leading experts on faulting and seismotectonics of the Southern California offshore region based on more than 30 years experience. He has mapped the major active and ancient fault systems of the area offshore southern California and northern Baja California, compiled, analyzed, and mapped the offshore seismicity and earthquake character, and is the author of more than 35 publications in scientific journals, books, and maps resulting from offshore geological and geophysical research. mark has also worked with the NASA Extreme Environments Project and helped train astronauts as to what types of rock they might find on the moon or Mars. He also studies underwater geology and faults, starting on scuba and then moving on to using underwater submersibles for his research, including the famed Alvin submersible.

UNDERWATER GEOLOGY AROUND CATALINA ISLAND
We live in an earthquake-prone area and those fault lines also ruin out into the ocean and affect things both above and below the water. Dr. Legg will tell you about some of those, describe some fascinating underwater events that have happened in spots where we regularly dive, and will leave you with a slightly different impression of what's happening geologically in our ocean than you may currently think.

Dr. Sam came to California in 1951 at the ripe age of 19 and quickly became a teen-aged free-diver. Scuba diving had just arrived in Southern California and Sam made his first dive in Laguna Beach with no wetsuit and cheap equipment. It was just a tank and regulator, fins and a mask, no snorkel. Formal diving instruction didn't exist until 1954. When you bought your diving equipment, you got a little pamphlet of about six or eight pages that you read and that was the sum total of instruction. In those days, every time you put your head underwater it was a new experience. But Sam was enamored and quickly moved up the scuba hierarchy. His instructor credentials have impressive low numbers: L.A. County OWSI #11, NAUI Instructor #27, and PADI Instructor #241. Since 1962 he ha authored numerous articles in local, national, and international publications. And he maintains what is likely the world's largest library of scuba diving books and publications. Sam was (and is) a charter member of numerous dive organizations and he also provided diving support for water impact testing on the Apollo Command Module, which included helping recover it when it sank to the bottom of the test tank.

IN THE ROOM WHERE IT HAPPENED
Dr. Sam Miller III has been around diving for a looooong time. When he talks about the history of the sport, he can do so not because he read about it in a book or magazine, but because he was likely there when it happened and knows first-hand. In this talk, he share some of those stories with you and give you a better idea of how this industry came to be created and evolved. Sam will use his personal knowledge as well as his extensive library to enlighten you on some of the history of this sport that we all love so much.

Doug and Lorenza Sloss have worked in the tourism and hospitality business for several years aboard the Aggressor liveaboards in Kona, Hawaii and Palau, Micronesia. There, they have taught hundreds of people how to dive and shoot photography. Their passion for teaching translated into the creation of a successful series of video tutorials that help photographers of all levels to effectively and professionally post-process their images. Their award-winning photography has appeared in Sport Diver, Scuba Diving, Scuba Diver Australasia, Islands, Asia Diver and many other magazines and books worldwide. Doug has been Field Editor and regular columnist for Scuba Diver Australasia magazine. They also lead photo workshops teaching photography and digital editing, both above and below the waterline.

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.
