Earth's Gravity Revealed

Above image looks like a giant potato, but it is actually our Earth. After just two years in orbit, European Space Agency's GOCE (Gravity field and steady-state Ocean Circulation Explorer) satellite has gathered enough data to map Earth's gravity with unrivalled precision. Scientists now have access to the most accurate model of the 'geoid' ever produced to further our understanding of how Earth works.


A precise model of Earth's geoid is crucial for deriving accurate measurements of ocean circulation, sea-level change and terrestrial ice dynamics. The geoid is also used as a reference surface from which to map the topographical features on the planet. In addition, a better understanding of variations in the gravity field will lead to a deeper understanding of Earth's interior, such as the physics and dynamics associated with volcanic activity and earthquakes.

Studio7

Each year, Studio7 (a West Coast design agency) donates a certain percentage of their profits to small charitable organizations around the world. Over time, these small donations are then paid back by the borrowers in an attempt to encourage free trade and market.

This is an 
infographic designed by Kelsey Smith (a graphic designer from United States, Massachusetts) to visually interpret the data collected from these donations, to help Studio7’s clients and partners better understand the results of their efforts.
