Offshore Argentina and Falklands - Enhanced Potential Field

This enhanced Offshore Argentina and Falklands potential field package includes gravity datasets that are based on the Sandwell and Smith Satellite Free-Air gravity v24.1 dataset from the Scripps Institution of Oceanography (SIO). A Low-pass filter with a cut-off wavelength of 30 km has been applied to the onshore data prior to enhancement processing to reduce the artefacts in the original data. A Bouguer and Isostatic Correction have been applied to the data and enhancements are supplied with the product.

The magnetic data source is the EMAG2 v3 2017 dataset.  The data has had a variable reduction to the pole applied to accurately locate and orient magnetic anomalies.  Frogtech Geoscience proprietary enhancements have been applied to the TMI RTP data and are included in this product.

The digital elevation data has been produced from the 1 km grid cell size SRTM30 Plus v11 DEM data from SIO. Frogtech Geoscience have produced enhancements and ternary images on the data to enhance boundaries. 

The Offshore Argentina and Falklands product is part of Frogtech’s range of low-cost, ArcGIS-ready Core and Enhanced potential field datasets available for immediate purchase and download from the Geoscience Store.

A Core product is also available in this area as well as global potential field packages.  

Frogtech specialises in rapid, high-quality custom potential field processing and geologically-constrained magnetic and gravity modelling.
