A dental surgeon by profession, Mark has been an avid ocean diver and underwater photographer since 1975. In that time, Mark has been published in many major journals, including National Geographic, Australian Geographic, and BBC Wildlife magazine. His assignment to photograph manta rays for a major feature on that animal won him Australian Geographic’s “Best Photographer” award for 2002.
In 1997, he was elected a Fellow International of the Explorers Club in New York. This honour mainly reflected his efforts to document various diving projects with respected journals such as Sportdiving magazine and Australian Geographic. His subject material covered shipwreck exploration, marine wildlife and cave diving.
In 2007, Mark was honoured by his peers in the diving community at an Australian Diving Technologies Conference with an “Outstanding Achievement Award” for his “Outstanding contribution, commitment & success in underwater photography and in cave & wreck exploration”.
In 1981 Mark learned the Transcendental Meditation technique and in 1985, the TM-Sidhis advanced meditation technique. The incorporation of meditation into his daily routine allowed him to experience the peaceful silent depths of consciousness not normally entertained at the superficial levels of wakefulness. He quickly recognized the qualities of consciousness experienced in meditation reflected those qualities he experienced in his deep-sea diving. The correlations deserved their own exploration and after years of research, the book Ocean of Self examines the nature of consciousness using the ocean as a metaphor.
