PRESS REPORT: "Although the San Juan was 6,000 kilometers from the nearest sensor on Ascension Island, the CTBTO was able to detect a tiny spike in sound waves that indicated a small explosion. "In the case of the Argentinian submarine, looking for an explosion signal this small was like looking for a needle in a haystack," says Lassina Zerbo, Executive Secretary of CTBTO."

COMMENTS: Rather than saying it was like looking for a "needle in a haystack," it would have been more accurate to have said "like looking for a very large telephone pole incompletely hidden in a very small haystack."

The SAN JUAN implosion signal was not a "tent-pole" in the background ambient, it was that telephone pole with an enormous signal-to-noise ratio. It could have been detected at ranges greater than the circumference of the earth if there had been an unobstructed deep-water transmission path.

"Small explosion," "tiny spike" ??? Try an energy release equal to the explosion of 11,475 lbs of TNT. The simultaneous explosion of the entire SAN JUAN torpedo load would not have equaled 11,475 lbs of TNT, and the SAN JUAN is reported not to have been carrying torpedoes.

The very fact that the signal was detected by CTBTO sensors at ranges as great as 4175 nautical miles with that enormous signal to noise ratio made it immediately apparent it was an implosion. If not blocked by the Mid-Atlantic Ridge, the SAN JUAN source should have been detected by every IUSS sensor in the mid- to eastern North Atlantic. It could even have "leaked" into the Norwegian Sea across the western side of the Iceland-Faeroes Gap ridge (sill).
