Answer: (B)

Channel 70 is designated specifically for Digital Selective Calling (DSC) in maritime communication, which is a key feature of the Global Maritime Distress and Safety System (GMDSS). DSC enables vessels to send automated distress alerts and routine calls without the need for voice communication, enhancing safety and efficiency on the water. This channel allows mariners to receive distress signals and communicate specific information such as vessel identity and location quickly and accurately. While there are other channels used for emergency broadcasts or public announcements, Channel 70’s primary function is related to the automated system that operates seamlessly to streamline communication for distress situations and routine ship-to-shore communications. Thus, understanding the use of Channel 70 is essential for ensuring effective maritime communication and safety practices, particularly in emergency scenarios.

When you’re out on the water, whether it's for recreation or commercial needs, communication is everything. You know what? That’s where Channel 70 swoops in, acting almost like a guardian angel in the maritime world. Imagine being in the middle of the ocean and hitting a snag—you'd want a reliable way to call for help, wouldn't you? This is where Digital Selective Calling (DSC) on Channel 70 truly shines.

So, what’s the big deal with Channel 70? This channel is dedicated specifically to DSC within the Global Maritime Distress and Safety System (GMDSS). It allows vessels to send distress alerts and routine communications without uttering a single word. Yup, it’s as revolutionary as it sounds! With just a click, you can communicate your distress status, identity, and location automatically. Talk about technology saving the day!

Now, you might be wondering, “What about other channels?” Here’s the thing: while other channels handle emergency broadcasts and public announcements, Channel 70 is that exclusive VIP room focused solely on automated communication. It’s like the well-orchestrated behind-the-scenes crew ensuring everything runs smoothly while the main act performs on stage.

When you understand the importance of Channel 70, you’re not just preparing for your safety exam; you’re actually arming yourself with critical information that can make all the difference in emergencies.
