Danger
HNS-MS is a decision-support tool that Belgian and French maritime authorities as well as coastguard stations can activate in order to forecast the drift, fate and behavior of acute marine pollution by Harmful Noxious Substances (HNS) accidentally released in the marine system.
HNS-MS has been funded by DG-ECHO under agreement ECHO/SUB/2014/693705 and runs from 1 January 2015 to 31 March 2017.
