Greenland Airborne Magnetic Anomaly Survey from Operation IceBridge

Magnetic field readings were collected over Greenland using a Scintrex CS-3 Cesium Magnetometer instrument aboard Operation IceBridge aircraft. The dataset contains Level 1B geolocated magnetic anomaly data. It is hosted by the National Snow and Ice Data Center (NSIDC) and was part of NASA's Operation IceBridge campaign.

Use Cases

• Mapping crustal magnetic anomalies over Greenland using geolocated magnetic field measurements.
• Analyzing temporal changes in the geomagnetic field from repeated airborne survey lines.
• Correlating magnetic anomaly data with other geophysical datasets (e.g., ice thickness, gravity) for subsurface geological modeling.
• Studying the relationship between magnetic signatures and geological structures beneath the Greenland ice sheet.

Strengths

• Data originates from the Operation IceBridge mission, a major NASA-funded airborne survey campaign.
• Specific instrument details are provided (Scintrex CS-3 Cesium Magnetometer), indicating a known measurement source.
• The dataset is available on multiple authoritative platforms (NASA Earthdata, Data.gov), suggesting established provenance.

Limitations

• Critical metadata such as row count, file size, and specific column names are unavailable from all provided sources.
• There is a conflict in the 'last updated' date between sources, with one reporting 2012-05-17 and another reporting 2026-03-13.
• The license is ambiguously listed as 'other-license-specified' or 'None', requiring further investigation for reuse.
