2D model and synthetic seismic and non-seismic data

A complete suite of synthetic geophysical data from a suite of 2-D models based on geological and geophysical information. These data provide reference datasets for the development and quantitative evaluation of inversion strategies for imaging and interpretation of the Earth's subsurface in challenging area with basalt layers.

The 2-D models are based on real seismic data, with the basalt layers being parameterised from mapping of exposed basalt sequences and rock physics from borehole logs drilled into basalt layers.

The synthetic data consist of seismic reflection data in shot gathers, the form in which it is acquired in the field, modelled using an accurate elastic finite difference scheme. These data are available with and without free surface multiple contamination. 2-D free-air gravity anomaly, 2-D magnetics profile along with a number of synthetic magneto-telluric stations and controlled source EM have been generated using the models.

The datasets may be used individually or in combinations to test which of the original model's physical properties can be recovered by particular inversion algorithms and their accuracy and sensitivity.

Both the data and the original model will be publicly available.
