(*) Before April 1997, the manual "bucket" method was
used to evaluate the quantity of dredged material onboard a ship.
Since April 1997, an automatic meaurement device is used which allows
to evaluate directly the quantity of dry material on board ships.
Comparison between both systems is not possible.
(1) Closed for dumping since end 2004
