Dr. Bruce Wienke
is the developer of the dive algorithm known as Reduced Gradient
Bubble Model (RGBM), which is based on the physics of bubble formation.
Wienke's research is in collaboration with the University of Rochester,
the University of Trondheim, Norway, the University of Wisconsin,
the National Aeronautics and Space Administration and the University
of Hawaii.
The benefits
of the RGBM are that divers can go deeper, stay longer and spend
less time decompressing than with the Haldane Table. Keeping nitrogen
and helium bubbles from forming in the body is the goal of both
the Haldane Table and RGBM. The advantages of RGBM stem from its
use of mixed gases, the most common trimix, heliox, and nitrox,
and a different approach to determining the depth and timing of
decompression stops upon ascent based on the properties of these
gases and their biophysical response to various levels of pressure.
A big part of
the reason for RGBM’s acceptance is Wienke's diving experience.
Wienke has logged more than 3,000 hours underwater as deep as 400
feet and in locations all over the world, from under the ice of
the arctic to the tropic waters of the South Pacific. Author of
five technical diving books, including "Basic Decompression
Theory and Application," and "Basic Diving Physics and
Application," Wienke credits RGBM’s success to a common
diving language.
