Actually, here's what the DAN site sez. They've got a thing...
"Project Dive Exploration (PDE) uses recording dive computers to collect
information about the depth-time profiles of volunteer recreational divers.
As of December 2003, PDE had collected more than 70,000 dive profiles
since beginning data collection in 1995.
The goals of PDE include creating a database of both safe dives and dives
that result in injuries. This will help provide insight into the behavior, dive
profiles and characteristics of recreational divers and their risks of decompression
illness (DCI).
Since its beginning, PDE has shared goals and methodology with Dive
Safety Lab (DSL), a similar program developed and conducted by DAN
Europe. DSL has collected more than 20,000 dives, many of them including
post-dive follow-up with Doppler detection of venous gas emboli.
With the encouragment of International DAN, both programs now share
the same computer platform that allows data to be merged. Joining the
efforts and data will accelerate the research and provide more power to
our analysis.
Dive computer manufacturers Cochran, Suunto, Uwatec / Scubapro,
DiveRite and dive recorder manufacturer ReefNet have strongly supported
PDE. Cochran and DiveRite have dive log software that allows divers
to email their PDE data directly to DAN. Suunto and ReefNet are working
on this capability within their software. "
