Abstract: The Divers Alert Network (DAN) is developing an observational field study called Project Dive Safety that will collect data on about one million open-water dives with the objective of prOViding information to assist divers in making informed decisions about the risks of decompression sickness (DCS). Recording dive computers will be used to document depth-time profiles, and trained Field Data Coordinators (FDC's) will interview divers concerning medical signs and symptoms. FDC's will use custom Data Acquisition Software to document these data and data on the divers and dive conditions. This information will be sent to DAN for analysis by statistical correlation of dive profile, dive conditions, and diver characteristics. Project hypotheses are that the DCS probability increases with the severity of the dive and is not the same for all divers. An index of decompression stress will be computed for each dive by estimating the DCS probability with statistical decompression models. While the project was initially conceived for recreational diving, scientific diving data are equally useful, and scientific diving FDC's will be trained as interest demands. The methods of Project Dive Safety will be used beginning in 1995 by the Institute of Nautical Archeology to document the introduction of a new set of in-water oxygen decompression tables for the excavation of an early shipwreck off the coast of Turkey. The background and development of these tables is described, and the tables are presented.
