The OCTek-GoM-Caribbean study has investigated the rifted margins and basins of the Gulf of Mexico and the Caribbean, within the region defined by 5-35°N and 50-100°W, where the study joins with OCTek-Atlantic.

The OCTek-GoM-Caribbean results will therefore be of interest to those exploring or evaluating the offshore basins of:
Gulf of Mexico,
Bay of Campeche,
Yucatan Basin & Cayman Trough,
Nicaragua Rise, Columbia Basin, Venezuela Basin
Demerara Plateau,
Florida-Bahamas Platform & Blake Plateau

The primary output from OCTek-GoM-Caribbean is a comprehensive suite of digital grids for the Gulf of Mexico & Caribbean region which show:
1 Depth to Moho
2 Total crustal thickness
3 Residual continental-basement crustal thickness
4 Crust and lithosphere thinning/beta factor
5 The residual thermal gravity anomaly at the present-day

The results have been tuned to local breakup/rift ages along the margins and to local crustal reference thickness. They also explore a range of plausible scenarios for the amount of volcanic addition during breakup.

The suite of digital grids is available for unrestricted use by purchasing companies and institutions and is supported by an atlas of maps, which documents the techniques and data used together with a map-plot from all of the supplied grids.

OCTek-GOM-Caribbean is based on analysis of data available in the public domain. OCTek gravity inversion is proven technology which has also delivered the OCTek-Atlantic, OCTek-Indian Ocean, OCTek-Asia/Pacific, OCTek-Arctic and OCTek Australasia studies together with confidential results on a proprietary basis from rifted margins worldwide.

A study applying the OCTek gravity inversion methodology to the conjugate South Australia – Antarctic margins has been made available for free public download by Geoscience Australia.
