An example of dynamic information transmitted by AIS is?

• A. Ship's name and length
• B. Course over ground (COG) and Speed over ground (SOG)
• C. Static ship position
• D. Weather conditions

Answer: (B)

Dynamic information transmitted by the Automatic Identification System (AIS) includes data that changes frequently and provides real-time information about a vessel's movement and navigation. Course over ground (COG) and speed over ground (SOG) are key indicators in this category as they directly reflect the current navigational performance and direction of the vessel. COG is the direction in which the ship is moving over the ground, while SOG indicates the speed at which the vessel is traveling relative to the ground, accounting for currents and other factors. This information is critical for safe navigation, especially in busy maritime environments, as it assists in collision avoidance and situational awareness. In contrast, the other choices represent either static information or data that does not change frequently in real-time. The ship's name and length, for instance, are considered static information because they remain constant throughout the voyage, while static ship position does not provide the dynamic element of movement. Weather conditions can be dynamic but are not typically transmitted by AIS in the same capacity as COG and SOG. Therefore, the selection of COG and SOG as dynamic information is appropriate and essential for understanding vessel operations in real-time scenarios.
