| Abstract: | In 2005, Geology Today carried an article (v.22, n.5) describing how 3D exploration seismic data are being used to map sub-surface structure and stratigraphy, in fine detail, over hundreds and even thousands of square kilometres of the sea bed. The article in question was concerned primarily with the various ways in which 3D seismic data are applied to the study of stratigraphy and basin analysis. However, the potential uses of 3D exploration data for investigating other kinds of geological phenomena are many and varied, and significant advances may be made in our understanding of the geological past using such data. The present article describes how 3D seismic data can be used to investigate aspects of the upper Tertiary and Quaternary geology of marine areas, drawing on examples from the Central North Sea and West Shetland Slope. These originally came to light in the course of conducting geo-hazard surveys on behalf of the hydrocarbons industry. |
