Earth Physics

The first sessions are devoted to reminders of the mathematical tools that will be used in the module. The teaching is then divided into three parts: geothermal energy, gravimetry and geomagnetism. The approach developed combines theoretical and practical approaches. Particular attention is paid to measuring and estimating errors during practical work.

Hourly volumes :

CM: 15

TD : 30

TP: 9

The depths of the Earth are largely inaccessible through direct observation. The aim of this module is to complement the seismological approach taught in^2nd year undergraduate studies, by presenting complementary geophysical tools that provide a better understanding of our planet's internal dynamics. Near-surface imaging measurements are also presented.
