Burglar Alarm for Ancient Shipwrecks

For those that don't use 45s and ARs here is something new to protect your wreck!

Acoustics 2008: Burglar Alarm for Ancient Shipwrecks

For all those interested in great naval disasters, lost underwater cities, shipwrecks, or The Life Aquatic with Steve Zissou, you might be interested in SEA-GUARD, an underwater intruder alarm system developed by Turkish scientists and presented at this year's Acoustical Society of America (ASA) meeting in Paris.

According to the authors of the paper, it is estimated that there are still about 1 million undiscovered ancient shipwrecks settled over the vast ocean floor. As more and more discoveries are made in the future, the potential for theft of valuable artifacts and damage to found vessels and cargo presents a challenge to those seeking to preserve these deep sea relics.

SEA-GUARD aims to protect these archaeological sites from unwanted or unauthorized visitors. It works by monitoring the underwater acoustic field, or sound waves surrounding the archaeological site.

Comprised of two sensor packages (one on the sea floor at the site, the other at a surface buoy), the device can detect unusual activity from disruptions in nearby sound waves. Not only that, artificial intelligence allows SEA-GUARD to analyze the specific behavior of an intruder, hence it is unlikely to confuse 5 grown men with a school of fish. Finally, once a genuine threat is confirmed, the system can send an alarm to authorities on land, via cable. Time to start searching for that buried treasure!

2 problems with sea-guard.It has a cable which can be cut.Also the unit itself can be stolen.Most shipwrecks are remote,so you wont be able to see who steals your Sea-guard.So that means you have to have a video camera aimed at your sea-guard and then another camera aimed at that camera an so on. to prevent theft.The only thelf prevention you can have that is fool proof is to hire 2 armed security guards with night vision for round the clock security.

HI FISH EYE my friend: Just being pickish, but I agre with you. You posted -->

A) It has a cable which can be cut.

Standard fail safe circuit takes care of this. Loses power or continuity triggers an alarm, which is transmitted to a sat. system monitoring this. thus the vessel will be identified as soon as it happens..

Also -->

so you wont be able to see who steals your Sea-guard.

Shucks a simple gps hookup takes care of that. Any change triggers the above alarm.

C) The only thelf prevention you can have that is fool proof is to hire 2 armed security guards with night vision for round the clock security.

I agree 100 %, however many governmental agencies will, since they don't pay for them themselves., and it makes them appear as if they are genuinely interested and efficient.
