A great story - sounds like a book to get

A great review at the New York Times:

Queenfish: A Cold War Tale
Atop the globe, the icy surface of the Arctic Ocean has remained relatively peaceful. But its depths have boiled with intrigue, no more so than in the cold war.

Although the superpowers planned to turn those depths into an inferno of exploding torpedoes and rising missiles, the brotherhood of submariners � the silent service, both Russian and American � has worked hard over the decades to keep the particulars of those plans hush-hush.

Now, a few secrets are spilling through a crack in the wall of silence, revealing some of the science and spying that went into the doomsday preparations.

A new book, �Unknown Waters,� recounts the 1970 voyage of a submarine, the Queenfish, on a pioneering dive beneath the ice pack to map the Siberian continental shelf. The United States did so as part of a clandestine effort to prepare for Arctic submarine operations and to win any military showdown with the Soviet Union.

In great secrecy, moving as quietly as possible below treacherous ice, the Queenfish, under the command of Captain Alfred S. McLaren, mapped thousands of miles of previously uncharted seabed in search of safe submarine routes. It often had to maneuver between shallow bottoms and ice keels extending down from the surface more than 100 feet, threatening the sub and the crew of 117 men with ruin.

I'm always a sucker for stories about submarines or anything underwater or arctic. The University of Alabama Press looks like a very dangerous place to browse... Fortunately, Amazon has it for about ten bucks cheaper: Unknown Waters Now did I just click that button???
