Gulf Wrecks

From today’s news:
http://www.chron.com/disp/story.mpl/hea ... 84688.html
What I really like about this story is the way the wreck was found.
It was while doing an oil pipeline survey.
The Gulf has a virtual spider web of pipes from the wells to collection points and then to on shore refineries.
The traditional way to do this was with are called “ROV’s.” (Remotely Operated Vehicles.)
The most famous being used in the movie Titanic.
The biggest problem they have is the tether to a surface ship.
That limits their depth and the weather they can be used in.
I get a magazine called Sea Technology that is about just that.
(The magazine is really good at shielding their stories from the net, so I cannot give you any useful addresses.
If you want to try, they are www.sea-technology.com.)
The October issue had 2 papers about underwater archeology in the Gulf.
One story was about ROV’s being replaced by AUVs (Autonomous Underwater Vehicle)
These machines can go deeper and farther because they are not tethered.
They were invented by the oil companies for sea floor route surveying but have found a number of unknown wrecks in the process.
The oil companies loan them out to archeologists when they are not using them.
The sonar systems on them give photo quality images.
The second story was from the point of view of “Permitting Agencies.”
State “Cultural Resource Managers” and the federal MMS (Mineral and Mining Service.)
It turns out that they are very much aware of the possibility of Submerged Prehistoric Sites in the Gulf, as well as anywhere else on the continental shelf.
I found it to be an encouraging example of co-operation between businesses, government, and academia.
(Boy, would I love for them to find an Egyptian/Phoenician/Libyan shipwreck.)
