Research Objectives: Magnetometers installed at selected sites in polar regions continue to provide measurements of the magnitude and direction of variations in the Earth's magnetic field in the frequency range from 0 to about 0.1 Hertz.

This project focuses on measurements of these variations using magnetometers installed at conjugate sites in the northern and southern hemispheres in Canada and Antarctica. The system collects data on the coupling of energy from the interplanetary medium into the dayside magnetosphere, including the magnetospheric cusp region, as well as on the causes and propagation of low-frequency hydromagnetic waves in the magnetosphere. Because of unique climatic conditions at the South Pole, optical measurements can be correlated with particle precipitation measurements and with hydromagnetic-wave phenomena recorded by the magnetometer.

Field Season Overview:
The support contractor's science technicians will work year-round in support of this project's magnetometer data-collection systems installed at McMurdo's Arrival Heights Facility and at South Pole Station's the Cusp Lab. The science technicians will perform daily checks of the equipment operation, maintain a log of panel meter readings, and monitor the magnetometers to ensure continuous operation. The University of Maryland's data recording systems acquire data at both locations.
