High Resolution Aeromagnetics

This might more correctly be termed "high precision aeromagnetics" The term has gained wide acceptance in the industry to denote surveys flown at low terrain clearance (80 - 150 m), with close line spacings (100 - 500 m), recorded at high sample rates (0.1 - 0.25 sec.), and acquired with high-sensitivity magnetometers (0.001 - 0.005 nT).
