We have not received an AIS report from Mariner of the Seas since then, so the position below is the last one we could confirm and not where she is now. Gaps like this are normal at sea: AIS relies on shore stations and satellites, and coverage drops on open ocean and in remote regions such as Alaska and the far north.
Position data last updated: . We check AIS every 30 minutes; an individual ship reports roughly every 1 to 2 hours.
