Magnetic Field Variations on Kerguelen Island

From January 14 to February 18, 1988, this dataset records minute-interval variations of magnetic field components at seven sites on Kerguelen Island. It contains measurements of the North, East, and Vertical magnetic elements in NanoTesla, recorded by a three-component fluxgate magnetometer. The data was collected by the Bureau central de Magnetisme Terrestre (France) and the Australian Antarctic Data Centre.

Use Cases

• Analyze temporal patterns in magnetic field components (North, East, Vertical) to study diurnal variations.
• Correlate magnetic field values with sensor metadata like temperature and battery voltage from block headers.
• Compare magnetic measurements across the seven sites to investigate spatial variability or the magnetic coast effect.
• Validate or calibrate fluxgate magnetometer models using the recorded full field values and truncated three-digit values.

Strengths

• High temporal resolution with data recorded at one-minute intervals.
• Multi-site coverage from seven distinct localities on the island.
• Includes auxiliary sensor data like temperature and battery voltage alongside magnetic readings.

Limitations

• Very limited temporal coverage, spanning only 36 days in 1988.
• Unknown total row count and dataset size.
• Data format involves a complex structure with block headers and truncated values, which may complicate parsing.
