They can do this only indirectly by being carried over a radio signal.
No. The transmitter of a radio station emits an electromagnetic signal that has been modified by sound waves that were converted into an electronic signal.
Sound is transmitted through water the same way it's transmitted through air -- by vibrations. Whatever is making the noise makes vibrations in the water, which then strike against your eardrum and vibrate it, and then the vibrations travel through some bones in your head to a bundle of nerves, which transmit the signal to your brain, which produces the sensation we call sound.
the Connecticut river flows into the long island sound.
Sound energy can be used to communicate information (e.g. talking). It can also be used to create delays in analog circuits by converting a electric signal travelling at approximately the speed of light into an audio wave, passing it through a medium, and then converting it back into an electric signal. The relative speed of sound to the speed of light causes an appreciable delay.

What happens is that a ship calls the lock attendant on a VHF radio channel. This lets them know. What channel, I'm not sure, but that could easily be looked up.
What river empties into the Pamlico Sound? The Tar and Neuse rivers empty into the Pamlico Sound
Communication is at speed of sound. Signal attenuation. Noise of signal travelling through air.

It is a microphone or a telephone.

The microphone accepts the our sound signal and input it to the computer. the sound is transfered through communication media.in this way the microphone works.
Because Audio waves move as sound waves through air as condensations and rarefactions or slight compressions and partial vacuums of gas molecules and can be stopped by the walls of a house.
