Mediterranean Sea Italy The Mediterranean Sea has an average depth - - PowerPoint PPT Presentation
Mediterranean Sea Italy The Mediterranean Sea has an average depth of 1,500 metres and is home to some of the worlds busiest shipping routes. These ships often carry hazardous cargo, which could result in serious harm to the environment if

To help mitigate this threat of environmental damage, the Italian government created a Ocean Data Acquisition System (ODAS) buoy network in 1989. With the requirement of updating the buoys in 2001, the Italian government became aware of considerable technological advances that had been made with new buoys to reduce the cost of gathering data and to make the data more useful to a broader audience.

In 2009, the Italian government awarded AXYS a contract to design, build, deliver and deploy 17 TRIAXYS- WatchKeeperTM buoys
- ver five months (July-
November).

Benefits
Increased knowledge of local marine conditions
Port authorities, fishing fleets, marine weather forecasters, and coastal zone managers can now retrieve current weather information from the network of TRIAXYSTM and TRIAXYS-WatchKeeperTM buoys.
SLIDE 15
Benefits
Better Decision-Making
Port operators now have information on wave and wind conditions which improves vessel traffic management in busy local waterways.
SLIDE 16
Benefits
Vessel Captains and other mariners in the Mediterranean Sea around the coasts of Italy can now make better decisions, such as deciding the best and safest route to travel.
Better Decision-Making
SLIDE 17
Benefits
Coastal engineers now have access to accurate data that can be analyzed for scientific marine applications.
