According to Jimmy Fazzolare this wreck consists of scattered wreckage with one mast stump sticking up. Jim reports that the wrecks bell was recovered by one of the Aquarians Club divers. Unfortunately, the bell did not have the wreck's name on it. Visibility here is often hampered by sediment from a silty bottom. Jim reports that this wreck is one of the best lobster wrecks in the area.

Decompression Theory

An Explanation of Professor A.A. Buhlmann's ZH-L16 Algorithm

by Paul Chapman

Note to new divers and potential new divers:

This information is presented for general interest. Don't be scared off by what you see here - you don't need to learn any of this to become a safe and competent scuba diver. You will however need to understand dive planning.

The following is a summary of the decompression algorithm described by Dr A.A. Buhlmann in the fourth edition of his book Tauchmedizin ( diving medicine ) published in 1995 ( only in German. ) the book contains a considerable amount of other information and is published by Springer-Verlag ISBN 3-540-58970-8. Rumor has it that at the time of writing ( November 1999 ) an English translation is being prepared for publishing, so hopefully, in due course, this document will become redundant.

The algorithm is simply a "recipe" for modeling the behavior of inert gases, which diffuse in and out of our body tissues when breathed under varying pressures. The intention is that if the recipe models the actual processes in our bodies accurately enough, it can be used to plan dives ( and other pressure exposures ) with a view to avoiding decompression sickness.
