Characterization Methods
The physical characterization of pressure ridges can be done using the following methods:
- Mechanical drilling, whereby augers designed for ice are driven through the ridge, and the core retrieved for analysis.
- Surveying, whereby a level, theodolite or a differential GPS system is used to determine sail geometry.
- Thermal drilling – drilling involving melting of the ice.
- Observation of the ice canopy by scuba divers.
- Upward looking sonars.
- A series of thermistors, to monitor temperature changes.
- Electromagnetic induction, from the ice surface or from an aircraft.

Famous quotes containing the word methods:
“I think it is a wise course for laborers to unite to defend their interests.... I think the employer who declines to deal with organized labor and to recognize it as a proper element in the settlement of wage controversies is behind the times.... Of course, when organized labor permits itself to sympathize with violent methods or undue duress, it is not entitled to our sympathy.”
—William Howard Taft (1857–1930)
