Aids TONavigation is the Coast Guard term for placing buoys, daymarkers, lighthouses, LORAN stations and other such items that help ships navigate in tricky waters.
I have no idea if markers had any effect on todays Cruise Ship Calamity, but a good buoy system does help prevent things like striking rocks. (navigation is just as important of course and there is the possibility that the rock was uncharted, either through recent geologic activity or oversight.)
Anyway, here is video of the cruise ship sinking. It is very fortunate that loss of life was so low.
Note that the Captain said the ship was actually taking on water which would seem to indicate hat this was not a ballasting issue, though if it was impropperly ballasted and had her cargo shift she could have submerged her scuppers and some other openings.
No, I really have no idea.
The closest I usually come to marine casualties is trying to prevent this sort of unpleasantness from happening with my vicious ticketbook. Actual smart folks have to do the post mishap investigations.
Update: Via Murdoc...Eaglespeak has a link to lots of pretty...OK, sad pictures.
Bird Flu Tsunami Islamic Millitants A particularly lethal volcano Now the earthquake .... followed by torrential rains to drown those buried in the rubble.
I'm a 37 year old UPS employee, college student, Coast Guard reservist,amateur diver and general geek. I hope to study in Japan in a few years and I'd like to move to the overseas territories, especially Guam. I do lean a bit to the right politically.....but you knew that if you looked at my blog.
I want to live long enough to walk on the Moon or Mars before I go.
