Bruce Wienke, Director of the Computational Testbed for Industry, Los Alamos National Laboratory, has a dedicated interest in diving. He is an Instructor Trainer with NAUI and serves on the Decompression Review Board. He is also a Master Instructor with PADI and serves on their Instructor Review Committee. In this book, Wienke addresses "need-to-know" information for training or diving in mountains or high plateau regions. In only 66 pages of easy-to-read text, accompanied by scientific charts, he explains why higher altitudes require changes in diving regimens and how to conservatively change protocols to rectify altitude differences.
