Carbon dioxide: some new perspectives on the old enemy

Carbon dioxide: some new perspectives on the old enemy
Carbon dioxide (CO2) is a by-product of the metabolism of oxygen in the body. It is eliminated by breathing but for various reasons that will be briefly discussed, diving (both on open circuit and rebreathers) exposes us to risk factors for CO2 “retention”. This is important because elevated CO2 has many potentially deleterious effects in…

Scrubber Monitoring & Work Of Breathing

Scrubber Monitoring & Work Of Breathing
A breathing apparatus is necessary if you want to breathe underwater. How do you know that it easy enough to breathe on it? Does your rebreather actually give the right O2 level? Most of such answers can be had from test with breathing simulators, water and pressure chambers. This talk will explain how some of the tests are done and…

Zodiac Connection

Zodiac Connection
Rob Palmer’s name is connected forever with this system. Left dormant for thirty years, besides few explorers diving it occasionally, Cristina has recently resumed a constant exploration and completed some interesting discoveries and connection, turning the Zodiac System into the Zodiac Connection.

Cuba: The Next Frontier for Karst Explorers

Cuba: The Next Frontier for Karst Explorers
Embargos and scant infrastructure have meant that Cuba has existed in the dark ages for cave explorers. A few fortunate cave divers have carved out diving relationships over the last two decades and yet the sheer wealth of cave resources has barely been touched. In early 2015, Jill Heinerth, Kenny Broad and Bil Phillips joined…

The fight for Abaco Island’s Crystal Caves National Conservation Area

The fight for Abaco Island’s Crystal Caves National Conservation Area
Exploration and Conservation of the world’s most beautifully decorated and scientifically significant underwater caves By Brian Kakuk Beneath a beautiful, pine-forested island in the Northern Bahamas lies over 10 miles of nature’s most exquisite and time wrought underwater caves. Known as the Crystal Caves of Abaco, these systems have been explored by a handful of…

Molecular Medicine and Diving

Molecular Medicine and Diving
Advancements in molecular medicine, a field focused on the molecular, genetic, and cellular changes or influences in disease or injury processes, are becoming increasingly important with respect to diagnostics, treatment of diseases and developing an improved understanding of what is happening in a disease state or following an injury. This presentation will provide an overview…

Helium Penalty?

Helium Penalty?
Breathing mixtures containing helium are used for deep dives, because helium is not narcotic and is less dense than nitrogen. In the late 1980's, pioneer technical divers adopted trimix (helium-nitrogen-oxygen) instead of heliox (helium-oxygen) for open-circuit deep diving. Trimix often contained a relatively low fraction of helium and high fraction of nitrogen, because these divers had limited infrastructure to mix…

WWII war wrecks of Gulf of Finland

WWII war wrecks of Gulf of Finland
Gulf of Finland was the most densely mined area in the whole world during World War II. Gulf of Finland saw two major evacuations during WWII, evacuations of Hanko and Tallinn. Russian Red Banner Fleet lost numerous warships and submarines. During the last years of war, Germany lost destroyers and U-boats while trying to keep…

Arctic cave diving

Arctic cave diving
Nordic countries offer a few but wonderful opportunities for cave divers. There are plenty of mines with crystal clear waters, but the mostly granite ground is not suitable for natural caves to form. In the region of Rana in Norway, there are about 200 known caves. Most of them are not appropriate for diving, either…

Roman Shipwreck search and survey. The Antikythera Mechanism wreck

Roman Shipwreck search and survey. The Antikythera Mechanism wreck
Found by sponge divers on standard dress using hand pumped air at 50-60 meters depth in 1901, the Roman Ship wreck off the North Eastern shore of the Island of Antikythera in Greece became famous for one particular artefact. The Antikythera Mechanism. Labeled the first analogue computer this fascinating and not fully understood artefact has…

Looking for Cave: Going Remote to Find Something New

Looking for Cave: Going Remote to Find Something New
Matt Vinzant will be presenting on cave exploration in the South East United States. Matt with a team of like-minded explorers has discovered a number of remote sinkholes and has been working to explore them.  Matt will discuss several new cave systems located in the Gulf of Mexico, a nearly mile long sidemount cave in…

Sidemount Simplified

Sidemount Simplified
Steve Lewis will be presenting on Sidemount Simplified. Sidemount diving: open or closed circuit. Some out there still eye it with suspicion, and remains for them it remains mysterious and misunderstood. Really! Hey, it’s just another way to carry cylinders of compressed gas, folks. Nothing magical, and in many ways safer and more useful than…

New Technologies In Explorations of Deep Caves

New Technologies In Explorations of Deep Caves
Krzysztof Starnawski will be presenting on some of the deepest, most extreme cave diving projects happening on the planet. He will discuss the organization of his cave expeditions and the use of dual sidemount CCR and underwater habitats. His underwater drills and dry caving techniques have led to unique dive plans and he will discuss…

Newfoundland: When the War Came to Canada

Newfoundland: When the War Came to Canada
During WWII, the mines on Bell Island Newfoundland supplied iron ore that accounted for one -third of Canada's steel production. If Germany interrupted this flow of ore, even temporarily, the war effort could be seriously affected. On the night of September 4th, 1942, a German U-Boat brought the battle of the Atlantic to Canada’ s shores. The story of the lost ships and men and their connection to the now submerged mine offers a fascinating look at Canadian history. Jill Heinerth, Steve Lewis, Gemma Smith and Phil Short will present a panel discussion highlighted by their…

The NASA NEEMO Project: Exploring Human Spaceflight Dynamics Underwater
For more than a decade, NASA has used saturation diving from the Aquarius underwater habitat as a real world environmental analog that bridges the gap between simulation and actual spaceflight. Presenter Karl Shreeves has been part of the NEEMO team since its inception in 2001, and presents a pictorial overview of NEEMO's use of high…

Thoughtful Management of Decompression Stress

Thoughtful Management of Decompression Stress
It is increasingly common for divers to rely on dive computers for their decompression safety, even (and perhaps more so) with extreme and complex exposures. While numerous decompression algorithms are available, they all rely on the pressure-time profile and mathematical strategies to estimate decompression status. Dive computers do not yet measure or integrate a multitude…
