SNAPPER'S EVENING OUT
During a particular phase of the moon in May and June dog snappers gather en mass from miles around to spawn at the same site on a deep outer reef of Belize. Although the huge aggregation of fish remains in loose groups for several days, actual spawning rushes and gamete releases occur only after sunset, at the very limits of video's light gathering capacity. Fortunately, John Halas had the use of a state-of-the-art camera when he recorded his extraordinary images. As predictable as the snapper spawn, whale sharks arrived on cue to sift fat-filled fish eggs from the sea.

John is probably responsible for saving more acres of living coral than anyone in the world. While serving as Sanctuary Biologist for the Key Largo National Marine Sanctuary, he designed, tested, and established a mooring buoy system for protecting coral reefs from anchor damage. John's methods have proven so successful that his technology is being implemented around the world, often under his supervision.

Certified in 1964, John has utilized scientific scuba diving skills throughout his career. After serving in Vietnam between 1966 and 1969, he participated in the SCORE saturation mission in Hydrolab (Lucaya, Bahamas) utilizing the Johnson Sea Link in submarine lock-out dives. In 1999 and 2000 he participated in the Sustainable Seas Program, and in Dr. Sylvia Earle's absence filled in as chief scientist for the 2001 Sustainable Seas Expedition/Mexico Leg sponsored by NOAA and the National Geographic Society.

John currently works for the National Oceanic and Atmospheric Administration in marine science conservation, research, and the management of coral reef environments. He also supervises scientific diving operations, and acts as scientific coordinator and dive supervisor for visiting scientists.
