1. Goce senses tiny variations in the pull of gravity over Earth
2. The data is used to construct an idealised surface, or geoid
3. It traces gravity of equal 'potential'; balls won't roll on its 'slopes'
4. It is the shape the oceans would take without winds and currents
5. So, comparing sea level and geoid data reveals ocean behaviour
6. Gravity changes can betray magma movements under volcanoes
7. A precise geoid underpins a universal height system for the world
8. Gravity data can also reveal how much mass is lost by ice sheets

As every part of the Earth is pulling on any given object at the same time, its hard to understand how changes in gravity can be measured. I know its possible, it just doesn’t seem so.

My sister bought what she that was a Goce, turned out to be a knockoff.
