About MXAK
Established in 2001 to fill critical information gaps and coverage in Alaska, MXAK has since become the leading source of maritime domain awareness across the state.
Mission
Provide information, communications, and services to aid safe, secure, efficient, and environmentally responsible maritime operations.
Founded out of necessity
The Marine Exchange of Alaska was established to strengthen safety, security, and environmental stewardship across Alaska’s vast maritime domain. MXAK pioneered one of the nation’s earliest comprehensive vessel tracking and information systems—providing real‑time situational awareness in some of the world’s most remote and challenging waters. Today, as a nonprofit headquartered in Juneau, MXAK continues its mission to support safe, efficient, and environmentally responsible maritime operations throughout Alaska and the greater Pacific region.
