Scientists are using satellite data to study large impact basins on the surface of the Moon that contain magnetic anomalies.
Mounting a magnetic sensor on a bicycle offers an efficient, low-cost method of collecting ground magnetic field data over rough terrain where conventional vehicles dare not venture.
The app sends local magnetic field strength along with your phone’s position and orientation to scientists, who use the data to fine-tune magnetic field models.
Madden, an AGU Fellow and a lifelong professor of geophysics at the Massachusetts Institute of Technology, was fascinated with all things electromagnetic. He died on 11 November 2013 at age 88.
Scientists used a noninvasive method to study the substructure of delicate groundwater-dependent ecosystems.
