Sonar detector.
A hygrometer is used to measure water vapor in the atmosphere. This instrument can measure humidity levels in the air to determine the amount of water vapor present.
Sound is simply the vibration of matter so it exists under water, in rocks, and even in lava.
A graduated cylinder or a beaker can be used to measure the volume or capacity of a water bottle by pouring water from the bottle into the measuring instrument and reading the volume indicated on the scale.
To measure the volume of a match, a graduated cylinder or a measuring cup can be used. By submerging the match in water and observing the displacement of the water, you can determine the volume of the match based on the amount of water it displaces. This method is based on the principle of Archimedes.
A tsunami buoy or tide gauge is commonly used to measure tsunamis. These instruments detect changes in water pressure and height to monitor tsunami activity. Additionally, seismic instruments can also be used to detect the earthquakes that trigger tsunamis.
Hydrophone
A sonar instrument emits sound waves to measure the ocean floor. The sound waves travel through the water and bounce back when they hit the seafloor, allowing the instrument to calculate the depth and map the topography of the ocean floor.
A hygrometer is used to measure water vapor in the atmosphere. This instrument can measure humidity levels in the air to determine the amount of water vapor present.

A hydrometer is typically used to measure the weight of water. It works based on the principle of buoyancy, where the instrument floats in water, with the depth of sinking indicating the density and weight of the water.
There are a lot of instruments used to measure water volume. There's also the displacement method to measure liquids.
The instrument used to measure the depth of the sea is called a bathymeter or echo sounder. It sends sound waves to the ocean floor and measures the time it takes for the sound waves to bounce back, allowing for the calculation of water depth.
Sound does travel under water otherwise the Humpback would be wasting its time singing!
When under power the sound of the engine and water lapping at the hull. When under sail the sound of water lapping at the hull.
No, decibel readers are designed to measure sound levels in air, not in water. Sound travels differently in water than in air, so specialized underwater acoustic equipment is needed to measure sound levels accurately in water.
Periscope
There are a few different ways you could measure the speed of sound in water and air. You could record the amount of time it takes a sound to be heard from the source to the destination for example.
