Answer to Question 1

After compensating for waves, tides, currents, and atmospheric effects, the ocean surface is still not perfectly flat. Because massive seafloor features exert stronger-than-average gravitational attraction, they produce elevated areas on the ocean surface. Conversely, canyons and trenches create slight depressions. Satellites equipped with radar altimeters are able to measure these subtle differences to the accuracy of a few centimeters by bouncing microwaves off the sea surface.

Answer to Question 2

Bathymetry is the measurement of ocean depths and the charting of the topography of the ocean floor.
