What do scientist call the charting of the ocean floor?
Bathymetry
What is at the bottom of lake?
The bottom is called bathymetry.
What is a bathymetrist?
A bathymetrist is a person who carries out bathymetry - the measurement of the depths of oceans or seas.
What is subsurface topography?
Underwater topography is typically referred to as Bathymetry.

How do satellites determine the terrain of the ocean floor?
Satellites use radar altimeters that are specially made tomeasurethe height of the ocean surface. The satellitesmeasurethe height of the ocean surface with an accuracy of 3cm realitve to the center of the earth.
How is sea level used to measure depth of the ocean?
A satellite named Jason 2 gives telemetry measurements of the ocean surface. It is now paired with an earlier satellite. Jason 1, and these tracks are interleaved to give comprehensive data. Interpretations are made, along with gravity measurements, to infer ocean bathymetry.
What do contour maps show?
Most people are probably familiar with contour lines found on topographic maps, which show elevation. Contour lines can also show weather and climate data, such as temperatures and humidity. Less common, bathymetry (the depth of water bodies) can also be shown using contours.

How is an echo sounder used to determine the bathymetry of the ocean floor?
They send down a sound wave (whose velocity they know) and measure how much time it takes for it to return. Velocity=Distance/time Distance=Velocity*time They divide the distance by 2 (since the sonar wave has to return as well.) They make thousands of these measurements to make a map of the ocean floor based on these distances.
