An interesting article in this weekend’s Sunday Times described an exciting plan to map the sea bed.
Scientists are planning to use advanced sonar on ships and submarines to scan the entire ocean floor ‘Google Maps’ style to plot mountains, trenches, volcanoes and other underwater features.
One great advantage of this project will be the mapping of submarine hazards currently not shown on marine charts. It is estimated that there are at least 100,000 unknown sea mountains over half a mile high.
This will all be made possible by the application of modern technology called ‘multibeam sonar which allows one vessel to map a swathe of sea bed hundreds of metres wide. Software can then turn the data into instant charts.
