SPECIAL LECTURES
Kronheim Lecture: June 3: 1300-1400
Guest Lecturer: Emory Kristof
Topic: "20,000 Bytes Under the Sea"
The National Geographic Magazine has been doing stories on the deep sea since William Beebe went “One Half-Mile Down” in 1934. The discovery of new life forms around volcanic vents, huge deep-dwelling sharks a mile down, shipwrecks such as the Titanic, Bismarck, and Edmund Fitzgerald have been covered by Emory Kristof in the pages and videos of the National Geographic. For over 30 years, submersibles and remotely operated vehicles (ROVS) have given him the access. In a talk illustrated with spectacular underwater imagery, Kristof will recount the challenges and solutions encountered in bringing back striking images from miles down in the world’s oceans.
About the Lecturer:
Emory Kristof
Principal Film Director
Emory Kristof has been a National Geographic photographer ever since working for the magazine as an intern in 1963. He is a specialist in scientific, high-tech and underwater subjects, including Deep Ocean work beyond normal diver depths. Throughout his career Kristof has been a pioneer in the use of submersibles and remotely operated vehicles. He created the preliminary designs of the electronic camera system for the Argo vehicle, which found the TITANIC. Including the TITANIC, he has documented many historic, deep, or challenging wrecks, among them the EDMUND FITZGERALD, the HAMILTON & SCOURGE, the BREADALBANE, the 16th Century Spanish Galleon, SAN DIEGO, and the interior of the USS ARIZONA.
His innovative photography also uncovers the heretofore-unexplored worlds of deep sea animals. He was on the 1977 expedition which discovered the deep hot water volcanic vents of the Galapagos Rift, and has done photography for six stories on the vents and their unusual life forms. He recently teamed with Stephen Low Productions to do the IMAX Film “Volcanoes of the Deep Sea.” He founded the Beebe Project with Teddy Tucker and Dr. Eugenie Clark in Bermuda to bring baited deep water sharks, and other animals to submersibles to be filmed and studied. Emory has worked for years with Chris Nicholson of Deep Sea System/Oceaneering to bring about the 10,000 foot Max Rover he used in the Arctic and Celebes Sea.
Bangasser Lecture: June 4; 1300-1400
Guest Lecturer: Robert Marx
Topic: "Hyperbaric Oxygen: Established and New Evidence Based
medicine in Radiation Injured Jaws"
The established and now time proven efficacy of Hyperbaric Oxygen (HBO) in radiated jaws is that of two protocols: The first is 20 sessions of HBO at 2.4 ATA for 90 minutes on 100% oxygen prior to surgery, followed by 10 such sessions after surgery referred to as the 20/10 protocol. This protocol addresses improved healing in the ares of the jaws that have received 6,000 cGy or greater. it is often termed an osteoradionecrosis (ORN) prevention protocol. However, although it may prevent ORN, it is actually a treatment protocol that established studies have shown creates a capillary angiogenesis that improves the radiation damaged tissue in a dose dependent fashion. The second protocol is 30 sessions of HBO followed by 10 sessions after either an assessment or a surgery termed the 30/10 protocol. This protocol pertains to the treatment of actual osteoradionecrosis with exposed bone. New data documents the safety in placing dental implants in radiated jaws and reduction in flap complications when flaps are placed into radiated tissue. In additon, our comprehensive study of 240 surgeries in head and neck radiated tissue documented statistically significant reductions in wound dehiscence, infections, and the need for revision surgeries in patients pretreated with HBO compared to those who were not.
