Marine communications refer to the systems and technologies used to exchange information at sea. This includes radio transmissions, satellite communications, and visual signals like flags or lights. These methods are essential for ensuring safety, coordinating navigation, and facilitating operations among ships and between vessels and shore stations. Effective marine communications help prevent accidents and improve response times during emergencies. They are crucial for various maritime activities, including shipping, fishing, and search and rescue operations. By maintaining clear lines of communication, crews can share vital information about weather conditions, navigational hazards, and other important updates.
