SCIENTIFIC AMERICAN FRONTIERS PROGRAM #1503 "Going Deep" AIRDATE: February 2, 2005 ALAN ALDA Hello and welcome to Scientific American Frontiers. I'm Alan Alda. It's said that the oceans, which cover more than two thirds of the earth's surface, are less familiar to us than the surface of the moon. If you consider the volume of the oceans, it's actually more than ninety percent of the habitable part of the earth that we don't know too much about. The main reason for our relative ignorance is simply that the deep ocean is an absolutely forbidding environment. It's pitch dark, extremely cold and with pressures that are like having a 3,000-foot column of lead pressing down on every square inch -- which does sound pretty uncomfortable. In this program we're going to see how people finally made it to the ocean floor, and we'll find out about the scientific revolutions they brought back with them. We're going to go diving in the Alvin, the little submarine that did so much of the work. And we're going to glimpse the future, as Alvin's successor takes shape in a small seaside town on Cape Cod. That's coming up in tonight's episode, Going Deep. INTO THE DEEP ALAN ALDA (NARRATION) Woods Hole, Massachusetts. It's one of the picturesque seaside towns that draw the tourists to Cape Cod each year. But few seaside towns have what Woods Hole has. For 70 years it's been home to the Woods Hole Oceanographic Institution — an organization that does nothing but study the world's oceans. -

Stefano Ruia
LA NARCOSI DA AZOTO di Stefano Ruia 1 - L’EBBREZZA DEGLI ABISSI La narcosi da azoto, definita dai medici “sindrome neuropsichica da aria compressa” (legata cioè alla respirazione di aria in pressione), è uno dei fenomeni che i subacquei imparano a conoscere subito, poiché influenza le immersioni a profondità già comprese nella fascia detta “ricreativa”, e con la quale tutti abbiamo dovuto imparare a convivere. Eppure ancora oggi la scienza non ha compreso del tutto i meccanismi biologici di questo stato di alterazione psicologica e ottenebramento mentale. Approfondiamo con questo dossier lo “stato dell’arte” su questo fenomeno, tanto comune e misterioso. Fu uno dei primi film subacquei che vidi. Era il “Il Mondo del Silenzio” di Cousteau, filmato – come operatore - da quel grande cineasta che sarà Louis Malle. Fu girato nella seconda metà degli anni ’50 dello scorso secolo. Beh, non sono così vecchio, ma quando la TV lo ripropose, qualche anno dopo, mi fu permesso di vederlo (allora per guardare la TV dopo “Carosello” i bambini dovevano ottenere – e non era facile - il permesso … bei tempi!). Una scena mi colpì molto. Durante una delle consuete “razzie” sui fondali (a quei tempi erano permesse e anzi rappresentavano la spinta più forte all’immersione con le bombole) il subacqueo perdeva il controllo e lo riacquistava solo in risalita. Aveva subito l’influsso della perfida “ebbrezza di profondità”. Questo terribile nemico mi metteva in agitazione, soprattutto quando mio padre partiva per andare a caccia subacquea al mare. Allora non facevo differenza fra apnea e autorespiratore. Così, come molti altri subacquei, sono cresciuto con l’idea che gli eroi della “Calipso” (la nave di Cousteau) per primi avessero scoperto questo tremendo fenomeno con cui fare i conti. -

It has been only 9 months since the Society was launched in October 1992, and membership has risen rapidly during this period. So rapidly, in fact, that it soon became obvious to the Steering Committee and myself that we would outgrow our position as the North American Chapter of the British Society and would have to restructure our organization. Firmly focusing on the Society's founding objectives of preservation and education, we have recently filed State and Federal papers to structure the Historical Diving Society as a non-profit educational corporation.

Surface-Supplied Diver Training Manual
Surface-supplied Diver Training Manual Tennessee Aquarium Chattanooga, TN Published by the Diving Control Board Tennessee Aquarium Chattanooga, TN 1st Edition 2007 Purpose Surface-supplied diving is defined in the Tennessee Aquarium Diving Safety Manual (TADSM) as a diving mode in which the diver in the water is supplied from the dive location with compressed gas for breathing and is in voice communication with the tender on the surface. This definition is based upon the requirements outlined in the Occupational Safety and Health Administration’s Code of Federal Regulations. (29 CFR 1910 Subpart T) This federal law outlines the criteria for all commercial diving. The surface-supplied diving mode requires gear and techniques that are not introduced in recreational diver training. This text was designed by the Tennessee Aquarium Diving Control Board to introduce Aquarium divers to the fundamental principles associated with surface-supplied diving. This text should be accompanied by proper practical training, as outlined in Appendix A, to promote safe surface-supplied diving under the auspice of the Tennessee Aquarium. Figure 1 – Secret Reef Dive Show- A primary use of surface-supplied diving at the Tennessee Aquarium. i Introduction There are numerous advantages to surface-supplied diving that make it an excellent choice for many diving operations. First, the diver has the benefit of an unlimited air supply. With a surface-supplied diving system, a diver can theoretically stay underwater forever. Of course, in reality, there are comfort, thermal, and decompression limits. For deep technical diving, a surface-supplied rig relieves the diver of the need to carry numerous stage bottles. -
