Presence
Presence in maritime context refers to the state of being in a particular location or area of the sea. It is the ability of a vessel to be detected by other vessels, shore stations, or satellite systems. Presence is an important aspect of maritime safety and security as it enables vessels to be tracked and monitored, and helps to prevent collisions, piracy, and other illegal activities. The presence of a vessel can be determined by various means such as radar, Automatic Identification System (AIS), and Global Positioning System (GPS). The ability to maintain presence in a particular area is also important for maritime operations such as search and rescue, scientific research, and offshore activities.
