Techniques

Key scientific techniques.        Gravity sensors: Map regional variations in the geoid (global gravity field) and density variations in the local underlying rocks. Radar: Reveals subglacial topography, subglacial lakes and layers in the ice. Magnetic sensors:  Map magnetic properties of underlying rocks.                                    Laser and ASIRAS radar: Ice surface elevation and shallow snow processes.
