Pearl Harbor ship salvage began immediately after the attack and continued until 1944. It was dirty, dangerous, detailed, (and discouraging) work for U.S. Navy salvors and divers, but their impressive repairs eventually returned eighteen sunken and damaged ships to wartime service. Only one was left where she fell. [More in the book Resurrection: Salvaging the Battle Fleet at Pearl Harbor.]

The Tricolor, a 50,000-ton cargo vessel carrying 3000 automobiles worth more than $40 million, is being raised. Cost to raise the Tricolor: $40 million. It sunk, then was hit three times, once by the Nicola, then by the Vicky (an oil tanker which spilled some, and killed marine life), then by a salvage tug. Good summary of the collisions in Dutch and English, with photos (similarly in French). Official press briefings offer good outline of all stages since the beginning. The automobile manufacturers tried to prevent pictures being taken of the destroyed automobiles, but there they are and even more and better. The official Tricolor salvage site offers a PDF file on how the salvage is being done: in part, with a huge cutting wire.

In 1628, the Swedish man-o-war Vasa sank to the bottom of the Baltic Sea moments into her maiden voyage. 333 years later this remarkably well-preserved ship was resurrected from her ocean grave and brought to drydock.

The Spiegel Grove was supposed to be sunk upright, creating the largest and most accessible artificial reef ever. Cool!

Unfortunately, the ship had other ideas and now appears to be impersonating a giant turtle. One of the nation's top marine salvage outfits has been called to the rescue. Looks like a potential Discovery Channel show in the making. (Check out the pictures on the Spiegel Grove site, they're pretty cool.)
