Maritime Domain Awareness has been defined by the International Maritime Organization (IMO) as the effective understanding of anything associated with the maritime domain that could impact the security, safety, economy, or environment. MXAK has developed a comprehensive system throughout Alaska providing Maritime Domain Awareness for ports, regulatory agencies, vessel operators, and maritime communities to promote safe, efficient, and environmentally sound maritime operations. The systems in place include vessel tracking, real time weather, tidal current information, and navigational aids including “Print on Demand” nautical charts.
