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. -

Bibliography of North Carolina Underwater Archaeology
i BIBLIOGRAPHY OF NORTH CAROLINA UNDERWATER ARCHAEOLOGY Compiled by Barbara Lynn Brooks, Ann M. Merriman, Madeline P. Spencer, and Mark Wilde-Ramsing Underwater Archaeology Branch North Carolina Division of Archives and History April 2009 ii FOREWARD In the forty-five years since the salvage of the Modern Greece, an event that marks the beginning of underwater archaeology in North Carolina, there has been a steady growth in efforts to document the state’s maritime history through underwater research. Nearly two dozen professionals and technicians are now employed at the North Carolina Underwater Archaeology Branch (N.C. UAB), the North Carolina Maritime Museum (NCMM), the Wilmington District U.S. Army Corps of Engineers (COE), and East Carolina University’s (ECU) Program in Maritime Studies. Several North Carolina companies are currently involved in conducting underwater archaeological surveys, site assessments, and excavations for environmental review purposes and a number of individuals and groups are conducting ship search and recovery operations under the UAB permit system. The results of these activities can be found in the pages that follow. They contain report references for all projects involving the location and documentation of physical remains pertaining to cultural activities within North Carolina waters. Each reference is organized by the location within which the reported investigation took place. The Bibliography is divided into two geographical sections: Region and Body of Water. The Region section encompasses studies that are non-specific and cover broad areas or areas lying outside the state's three-mile limit, for example Cape Hatteras Area. The Body of Water section contains references organized by defined geographic areas. -

We also examined the revised histories issued by the US Coast Guard Historical Center and the US Naval Historical Center, both of which claimed The U-869 the sinking was a result of a depth charge attack by two US Navy vessels in 1945. The conclusion we reached was that the attack by the destroyers was most likely Reexamined, Part on the already-wrecked U-869. If our conclusion is correct, then how did the U-869 come to be on the III bottom of the Atlantic? The Loss of the German Submarine Early Theories The most effective and successful branch of the German By John Chatterton, Richie Kohler, and John Yurga Navy in World War II was the U-boat arm. Hitler feared he would lose in a direct confrontation with the Royal Navy, so the German surface fleet largely sat idle at anchor. Meanwhile, the U-boats and their all- volunteer crews were out at sea, hunting down enemy vessels. They sank the merchant vessels delivering the Allies’ much-needed materials of war, and even were able to achieve some success against much larger enemy warships. -

He also founded dive-related companies involved in manufacturing, pub- lishing, training agencies, resorts and liveaboard vessels, making him one of the industry’s most successful entrepreneurs. But one single feat astounded the diving world: the deepest dive on air. 1990 1990 “On memory and instinct, I passed through the arch and on the surface with his face in the water breathing through a cave, which was filled with schooling baitfish that obscured snorkel and then five minutes more with no mask breathing the visibility. As I reached the exit, the schooling fish opened from a spare tank at 15 feet below the boat. This invokes the up and the steep drop-off wall was revealed. -
Uss Bass (Ss-164)
USS BASS (SS-164) FIRE IN THE AFTER BATTERY This is a recollection of a fire on the USS Bass (SS-164) told by BMC (SS) Jack Stevenson who served on her from 1940 till 1943. Jack is known to his friends and shipmates as “Panama Jack” and resides in Colorado. Jack served in the Navy from 1936 until his retirement in 1958 and had tours as a Chief of the Boat (COB) aboard the USS Cob (SS-164), USS Sennet (SS-408) and USS Sea Cat (SS-399). Jack is a member of the Submarine Veterans of WWII and the Submarine Veterans, Charleston Base. The Bass (SS-164) was the first fleet type submarine built and was commissioned in 1925. She was 342’ long with a displacement of 2,000 tons surfaced and 2620 tons submerged. She had a surface speed of over 19 knots and submerged speed of 9 knots. Her test depth was around 200’ and had a range of about 6000 nautical miles with a crew of 50 enlisted and 6 officers. She had an unusual design as the engine rooms where split forward and aft which probably led to the severity of the fire. The forward engine room was used for power and drove the ships generators and the aft engine room was directly coupled to the shafts and was used for propulsion. After the fire she was converted to a cargo submarine and the after engine room was removed and the forward engine room was used to charge the batteries for propulsion. 1 In the summer of 1942 the USS Bass (SS-164) was deployed on her fourth war patrol from her base in Coco Solo, Panama. -
