Geophysical survey data, Greenland

The dataset comprises geophysical survey data available through the Greenland Mineral Resources Portal. The data include both released company data and publicly funded survey data, primarily airborne electromagnetic (AEM) and aeromagnetic (Aeromag) surveys.

The AEM Greenland 1994–1998 project encompassed high-resolution, multi-parameter airborne surveys including electromagnetic, magnetic and partly radiometric measurements conducted between 1994 and 1998, producing approximately 75,000 line kilometres of data.

The Aeromag projects included high-resolution airborne magnetic surveys conducted in 1992, 1995, 1996, 1997, 1998, 1999, 2001, 2012 and 2013, producing more than 550,000 line kilometres of data. The projects were financed by the governments of Greenland and Denmark.

The dataset provides regional geophysical coverage supporting geological interpretation, mineral exploration and geoscientific research in Greenland.

Statement

The dataset represents a compilation of airborne geophysical surveys conducted in Greenland between 1992 and 2013. It includes publicly funded surveys (AEM and Aeromag) and released company data made available through the Greenland Mineral Resources Portal.

The AEM surveys were conducted between 1994 and 1998 using multi-parameter airborne systems measuring electromagnetic, magnetic and radiometric responses. The Aeromag surveys were conducted in multiple campaigns between 1992 and 2013 using airborne magnetometers. Data acquisition was performed using systematic flight line spacing and GPS positioning, ensuring compatibility between surveys. Detailed technical documentation is provided in Geology and Ore No. 22.
