their optimal position. BSH may update to this new version of the GUI, if the users of 
the BSH SeatrackWeb desire to use the new feature. Apart from new features the new 
GUI has the advantage that it does not need die Java Web Start, because it is simply web 
based meaning that only a web browser is needed, which makes it easier to use Seatrack 
Web on mobile devices. 
Also interfaces to AIS web services, CSN oil spill detections and to PADM are con 
stantly updated to facilitate the exchange of input data and drift results for different ap 
plications. The AIS data covers mainly die Baltic Sea, since suitable data bases and inter 
faces to the North Sea data are still under development. Having AIS data of the North 
Sea would especially be important for prosecuting authorities to display AIS ship tracks 
and drift trajectories in a common window. 
5 Acknowledgement 
First of all we would like to thank the SeatrackWeb developer groups at SMHI and 
FCOO, where most of die mentioned Seatrack Web features have been developed over 
the past years. The observations and pictures of die container drift case were kindly pro 
vided by die Wasser- und Schifffahrtsamt Cuxhaven. Special thanks also go to die crew 
of the GS Neuwerk for plotting container positions. Last but not least we would like to 
thank the BSH sections M14, M23, M42 and Z32 for supplying wind/wave data and for 
the teclmical support.
