In terms of signaling distress, what does “DSC” stand for?

The term "DSC" stands for Digital Selective Calling. DSC is a method used in maritime communication, particularly in the Global Maritime Distress and Safety System (GMDSS), to send distress signals automatically and selectively to specific vessels or shore stations. This capability enhances the efficiency and effectiveness of distress calls by allowing for rapid communication without the need for voice transmission.

With DSC, a vessel in distress can transmit a signal that includes vital information such as its identity, position, and the nature of the distress, all at the push of a button. This system reduces the time it takes for rescuers to respond to an emergency and helps to ensure that the appropriate assistance is directed to the vessel in need. Understanding and recognizing DSC is crucial for mariners, as it plays a pivotal role in ensuring safety at sea.
