Estimates of Geological and Geophysical Surfaces (EGGS) database

The EGGS database contains point depths to chronostratigraphic surfaces obtained from boreholes and four magnetic modelling methods. In regards to the depths obtained from inclined boreholes there are uncertainties on their measurement of the true vertical depths. These are currently being looked into and would be resolved in due course. Future development will include AEM, reflection seismic, MT and passive seismic. A Web Service will allow the public to download this data and will be accessed through the EFTF (Exploring for the Future) web portal.
