1. What is bathymetry?
Bathymetry is the measurement of the depth of water in ocean and rivers.
2. What is the difference between a bathymetric map and a topographic map?
A bathymetric map is when lines are used to show the slop and elevation of land features. A topographic map is when lines cannot point of equal equation.
3. How can oceanographers map the ocean floor in the past? What were the results?
In the past oceanographers would throw a heavy rope over the side of the boat and then record the length of the rope. The results were in accurate.
4. How do oceanographers map the ocean now? And how accurate and effective is this method now?
Now oceanographers used something that is called a sonar or also known as echo sounder. And has limited accuracy.
5. What are multibeam echo sounders effective?
- They are able to measure a small area of the sea floor.
6. What's an example of underwater discovery that was made possible by multibeam echo sounders?
- Thousand of seamount discovered in the pacific ocean.
7. Why do oceanographers map the ocean below the surface?
- Bathymetric measurement supports safe navigation and protect marine environment. They can predict tusnami.
