Modelling remote sensing geophysics

The new Earthlearningidea today is 'Modelling remote sensing geophysics; using a mock gravitometer and magnetometer set up in the classroom'

This activity involves using a mock gravitometer and magnetometer to demonstrate the principles of the remote sensing of gravity and magnetism. It is an ELI+ activity. This method models how density and magnetic anomalies are identified by geophysical remote sensing. Data from such geophysical sensing is used to plot gravity and magnetic anomaly maps, like the ones shown above and explained in the activity.
