From NOAA, BOEM: Historic, 19th century shipwreck discovered in northern Gulf of Mexico:
During a recent Gulf of Mexico expedition, NOAA, BOEM and partners discovered an historic wooden-hulled vessel which is believed to have sunk as long as 200 years ago. Scientists on board the NOAA Ship Okeanos Explorer used underwater robots with lights and high definition cameras to view remnants of the ship laden with anchors, navigational instruments, glass bottles, ceramic plates, cannons, and boxes of muskets.
Very cool. Read the rest here: http://www.noaanews.noaa.gov/stories2012/20120516_okeanusexplorer.html
