Deep and dark, the Mud Hole is the Hudson River's channel from a time when the oceans were much lower. Today it collects all the silt and sediment that the river carries out to the sea, making it a very fertile fishing ground, frequented by pelagic fishes and sharks. The contour shown on the chart is not any particular depth, but do give an idea of the location.
With depths ranging from 130 to 200 ft and difficult diving conditions, most Mud Hole wrecks are beyond the capability of a typical recreational diver without specialized equipment and experience. Where river water mixes with seawater, suspended particles form a constant snow of sediment in a process known as flocculation. This results in very dark and turbid conditions, often with visibility measured in inches and total darkness at the bottom. In addition to this, most Mud Hole wrecks are heavily fished and are covered with dangerous tangles of monofilament and fishing nets.
The Mud Hole deepens into the Glory Hole, which deepens further into the Hudson Canyon, which follows the path of a seismic fault and eventually runs off the edge of the continental shelf down into the abyss at over a mile depth. Along the northeast edge of the Mud Hole is a relatively shallower plateau known as the Monster Ledge, on which lies the most well-known and accessible Mud Hole wreck, the Arundo.
Interestingly, all of the wartime Mud Hole wrecks with the exception of the Arundo are victims of collision rather than enemy action, which attests to the enormous amount of shipping in the region at that time.
Not marked on the chart: Salvatore "Big Pussy" Bompensiero, former Soprano family capo and FBI snitch, 2000. Sleeps with the fishes.

This is erroneously called a tug, but its shape and size indicate that she was once might have been a small oiler or tanker. The wreck lies upright in the muddy bottom at 120 feet. She comes up 15 feet off the bottom in many places and is mostly intact. I have little idea of age, but her conditions suggest she's been there for 30-40 years or more.
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.
