ULF geomagnetic field measurements at Terra Nova Bay (Antarctica)
Listed in NASA Earthdata CMR
Measurements of geomagnetic field variations in the ULF frequency band (1 mHz - 1 Hz) are made by a triaxial search-coil magnetometer at Terra Nova Bay (TNB, Antarctica) since 1992.
Description
The present data set are measurements made by a renewed instrumentation installed during the Antarctic campaigns 2001/2002 and 2002/2003. This new instrumentation consists of magnetic sensors with high sensitivity (2-3 mV/nT/mHz in the 1 mHz - 100 mHz frequency band) and of an acquisition system which allows a continuous recording (at 4 Hz sampling rate and timing via GPS) also during the austral winter.
