MDAT – GoG reports are primarily based upon information sent by vessels using the Voluntary Reporting Scheme. Masters and CSOs are encouraged to report as early as possible, events or sightings with as much detail as possible to allow MDAT-GOG to initiate the appropriate response. Sometimes incomplete reports cause delay to the issue of warnings and our ability to contact Local Navy assets for assistance. Masters are requested to call MDAT-GoG (+33 298 228888) at the time of any incident occurring. This phone number is monitored permanently (24/7). It is requested the Masters contact MDAT-GoG as soon as possible to facilitate quicker actions by the MDAT-GoG and their regional contacts.
