Despite the fact that satellites have been providing shipping services for many years they have not – up until now – provided a comprehensive snapshot of traffic patterns over time.
Now, a map has been created using an algorithm that detects ships.
Developed by Dr Vincent Kerbaol and Guillaume Hajduch from the French space agency, CNES, the algorithm makes it possible to process the movement of ships in near real time.
As some ships run on a dirty form of fuel that releases sulpher dioxide (SO2) and nitrogen dioxide (NO2) the mapping system can be used to trace emissions to specific ships.
The system will also have positive implications for maritime safety.

Is Windows Vista Service Pack 1 coming out soon?
No. We expected it this October or November. Now, however, a note published by the US Department of Justice says that "Microsoft anticipates that beta code will be available by the end of the year." That could push Service Pack 1 into next year.
