"We were forced to evacuate the remotely operated vehicle, 'Jason II,' several times to avoid getting it enveloped in volcanic clouds," said Bill Chadwick, ...one of the authors of the study. "But at other times, we could observe the eruption from only 10 feet away - something you could never do on land. So in some ways, we were able to see processes more clearly at the bottom of the ocean than we ever could on land. That was surprising." From KGW (bugmenot). Podcasts, videos, images, sounds, daily logs, and lots of information can be found on the project's website.

The Confederate Submarine HL Hunley and some background on the controversy surrounding its discovery. Turns out it was not discovered in 1995 as originally thought, but in 1970 by Dr. Lee Spence.
