Which safety protocol is enhanced by the Global Maritime Distress Safety Service?

The Global Maritime Distress Safety System (GMDSS) is designed to facilitate effective communication during maritime emergencies. This system enhances crisis communication by ensuring that vessels in distress can quickly and reliably communicate their situation to rescue services and nearby ships. The integration of various technologies, such as satellite communications, digital selective calling (DSC), and emergency position-indicating radio beacons (EPIRBs), allows for swift dissemination of distress signals and enhances the overall response to emergencies at sea.

In contrast, the other options do not directly relate to the primary function of the GMDSS. While oil spill response, sea navigation marking, and the use of lifejackets are important safety measures, they do not specifically pertain to the crisis communication capabilities that GMDSS provides to improve response times and coordination during urgent situations at sea.
