In Search of New Life by: Curt Bowen
Imagine a world of complete darkness. A hostile world where food is scarce and opportunistic predators lie around every corner. You are the hunter and the hunted. Your only link to the black environment around you are the tiny, vibration-sensitive hairs that cover your body. You sense movement in the distance, could it be food? Or is it a larger predator, slowly stalking your every move, waiting to snatch you up in razor-sharp claws and make you its next meal.
Cis-Lunar Rebreather by: Richard R. Nordstrom
The MK-5P ECCR is not just a cave diver's dream. This is a serious system for everyone. Be it cave divers, shallow divers, deep divers, wreck divers, underwater photographers, filmmakers and many more. Why would so many people with such diverse needs be interested in the same device? The answer lies in its technology and the company that designed and makes the MK-5P.

Scientific Diving by: Joe Rojas
There are five professional fields, or disciplines, recognized by today's dive industry and by the federal government: Military, Commercial, Recreational, Rescue and Scientific. Of these, the one least familiar to the general diving community is scientific diving. Scientific diving is done solely as a necessary part of scientific research, or as an educational activity for employees whose sole purpose is to perform underwater research tasks. The scientists that work in the profession as scientific divers are not the stereotypical pocket protector-wearing men and women who have poor social skills, but scientists that wear specialized dive equipment and spend endless hours underwater conducting research.
GUE - Britannic Expedition by: Anthony Rue
Nearly 100 years after the sinking of the world's most luxurious liner, the Titanic continues to captivate public sentiment. The tragic mystery surrounding the sinking of the Titanic becomes even more remarkable when taken together with the fate of her larger and more enigmatic sister- the Britannic. While extreme depth and a remote Atlantic location limits access to the Titanic, exploration of the Britannic is finally becoming a possibility to a select few organizations willing to commit the resources to further our understanding of the last great ship of the White Star Line. Global Underwater Explorers, under the leadership of Jarrod Jablonski, brought together an international team of two dozen trimix and support divers to explore the Britannic during the summer of 1999.
Artifact Preservation - IRON by: Andrew White
Iron has been used by man for centuries as a building material. It is one of the most plentiful metals found on the earth. Iron artifacts recovered by divers include portholes, knives, flintlock pistols, running light frames, and a wide array of other interesting items. However, when left in a saltwater environment for long periods of time iron is vulnerable to oxidation, where acids and chlorides create an electrical charge that corrodes the metal compound. In older artifacts, oxidation has caused a level of marine biological growth to encapsulate the object. This growth, called a concretion creates a highly acidic layer on the artifact that greatly increases corrosion.
Duane & Bibb - Key Largo Florida by: Chris Williams & Linda Bowen
The USCGC Duane was so named after William Duane, Secretary of the Treasury to President Andrew Jackson. Launched and commissioned in 1936, she was built at the Navy Yard in Philadelphia, Pennsylvania. The Duane was also a 327-foot Cutter, and her primary assigned duties were law enforcement, as well as search and rescue off the coast of California.
Cannon Ball Cave by: Joe Rojas
Cannonball cave, formerly known as Davidson's Blue Hole Outflow, created a hillside pool and a small creek that fed into the St Francis River 100 yards to the west. It had a flow of approximately 31.7 million gallons per day, which is small in comparison to some of the other Missouri springs. In 1939, the U.S. Army corps of engineers built a public flood control reservoir for the St. Francis River and all its tributaries. The dammed river flooded over the spring's mouth and surrounding area, creating a reservoir called Lake Wappapello. The entrance to the spring now lies at an average depth of 28 feet depending on the dam's water level. On a calm day it isn't uncommon to see the boil that is created by the turbulent spring water in the murky-still reservoir.
RGBM Deep Stop Modeling by: Timothy O'Leary & Bruce Wienke
At DEMA 2000, NAUI Worldwide introduced a new training CD for Mixed Gas Diving, which includes ranged trimix and helitrox decompression tables developed by Bruce Wienke, Ph. D. These tables employ the Reduced Gradient Bubble Model (RGBM) that incorporat
Cave Survey Techniques by: Curt Bowen
Brian Kakuk once said 'If you didn't survey the cave you were never there.' Meaning if you discovered a new cave system, or a new tunnel in an old system and didn't complete a detailed survey, you couldn't prove that you were really there.
Wes Skiles - Capturing Nature by: Wes Skiles
North Florida's rivers, and springs are the canvas that I choose to focus my effort. Born and raised here, I feel fortunate to have grown up in the land of mysterious waters. The first time I pulled back the bushes and saw a spring I knew these magical places would be a permanent part of my life. Our area offers one of the greatest natural wonders on earth. A giant, three-dimensional karst terrain that produces a renewable resource of the finest water on earth. I can think of no place on the planet more worthy of my attention and love than my own backyard.
Survival at Sea by: Andrew White
The world's oceans are one of the last, true frontiers. Covering four fifths of the Earth's surface, they present a hostile environment, and one of the most difficult in which to survive. As open water divers we routinely trek into the oceans to explore the wonders of this alien world. Our adventures often lead us far off the beaten path, and many times we take for granted the fact that we can get home safely, but emergency situations arise when we least expect them. Being prepared for an emergency and committing to memory a few survival techniques can be invaluable should a disaster occur.
