2 Shipwrecks, Snags and Obstructions : Definition Wreck : Everything, being from up water and laying on the bottom can considerate as a wreck as long he is identified Obstruction And Snagg : Obstructions could be wreck but also any unidentified object on the bottom.Rock, wood, ancient piece of shipwreck, cable Different scales of danger Spatial Temps Punctual Linear

3 Shipwrecks and Obstructions : Danger Pollution Shipwrecks, Cargo Diving Shipwrecks, rocks Fishing Shipwrecks,snags, Brittle star, rocky bottom, cable Navigation Isolated danger

4 Shipwrecks and Obstructions : Database Creation Progressive building 1980 CERES Fishing vessels GPS numbers Hand made charts

5 Shipwreck and Obstruction : Database Evolution location (Seine bay) location (France) location (France) location (Europe)

6 Shipwrecks and Obstructions : Database Evolution 2000 : CERES - INTECHMER Collaboration Database software development locations of shipwrecks and snags text files different documentations 150 fields per shipwreck 1 page of text Name, build, year of building, number of crews, engine. Date of sank. Casualty of sinking ….. Etc..

7 Shipwrecks and Obstruction : DATA processing

8 Shipwrecks and Obstructions : Side Scan Sonar Result Tow Fish Principe

9 Shipwrecks and Obstruction : Vidéo / Photo / Drawing

10 Shipwrecks and Obstructions : DATABASE utility Preventive utility : Network exchange of snags locations Obstructions and snags identification, difference between old wooden remains and rocks Neutralization of submerged dangerous product Granulates exploitation Dredging Pipeline and underwater cable

11 Shipwrecks and Obstructions : DATABASE utility Cultural and history 16 th century shipwreck US Civil wars shipwreck D Day shipwreck

12 Shipwrecks and Obstructions : Future Collaboration between, companies, states, unofficial and official oceanographic organization Exchange of data standardized Compatibility between GIS and navigation software Links between European oceanographic services Northern Europe extension
