Which item describes the mariner's movement history from departure to present?

• A. Description of vessel's trackline from departure to present
• B. AIS beacon status
• C. Last storm report
• D. Cargo manifest

Answer: (A)

Tracking movement history comes from a record of where the vessel has been over time. The description of the vessel's trackline from departure to present provides a continuous, chronological record of its positions and route, showing how it moved from leaving port to the current location. This path, with timestamps, captures the mariner’s movement history in a way that other data do not.

AIS beacon status only tells you whether the AIS signal is active or whether the beacon is functioning, not where the ship has traveled. A last storm report gives weather conditions encountered, not the actual route. A cargo manifest lists goods aboard, not the vessel’s movements. So the trackline description is the item that best describes movement history from departure to present.
