The rope is not as accurate as the sonar. The rope can move due to the ocean currents.
SONAR
Scientists use sound waves to measure the depth of the ocean through a method called sonar. By sending sound pulses from a ship to the ocean floor and measuring the time it takes for the sound waves to bounce back, scientists can calculate the depth of the ocean at that location.
Scientists use echo sounders or sonar technology to measure ocean depth. These tools work by sending sound waves down into the water and measuring how long it takes for the sound to bounce back, allowing scientists to calculate the depth of the ocean floor.
Scientists measure ocean depths using sonar technology, which involves sending sound waves into the water and measuring how long it takes for them to bounce back. Another method is using satellite altimetry, which measures the sea surface height and then estimates the depth based on the gravitational pull of underwater features. Submersibles equipped with depth sensors can also be used to directly measure the depth of the seafloor.
Depth
Measure the depth using a metric ruler!
To measure the jamb depth of a door, use a tape measure to determine the distance from the front edge of the door frame to the back edge. This measurement will give you the jamb depth of the door.
You can use a penny for that. Put in between the threads then mark and measure the depth on the penny.
To find out the ocean`s depth
No, a calorimeter is not designed to measure depth. It is a device used to measure the amount of heat released or absorbed in a chemical reaction or physical process. To measure the depth of something, you would typically need a different type of instrument, such as a ruler, tape measure, or a depth gauge.
Data from Clementine's laser altimeter was used to measure the thickness of the moons' crusts by mapping surface topography and detecting variations in elevation. These measurements allowed scientists to estimate the moon's crustal thickness by analyzing the depth of impact craters and other surface features.
Fathom which is six feet or two yards in depth .
