The OCTek Seismic Black Sea study has investigated the crustal structure of the offshore Black Sea region, based on a quantitative analysis of the ION Geophysical Black SeaSPAN seismic survey. A full description of the seismic survey can be found here

The quantitative analysis is based on the ION interpretation of the survey, a summary of which has been published here

The primary output from OCTek Seismic Black Sea is a line-by-line analysis of the survey, captured in illustrative montages of the profiles showing:
1 Moho depth and crustal-basement thickness, including display of this information on the PSDM and PSTM seismic sections (see below)
2 Crustal structure across the Ocean-Continent-Transition and the location of the Continent-Ocean-Boundary
3 The predicted distribution of volcanic rocks within the OCT
4 Crustal thinning-factor and beta-factor, as input for petroleum systems modelling. This is complemented by a guide on how to convert the results of the analysis into estimates of basement heat-flow history

Geo-referenced digital results for each seismic line are also provided, together with a selection of 3D digital grids compiling the results (see above).
