Bayesian Strategies to Assess Uncertainty in Velocity Models (2012)
Journal Article

Quantifying uncertainty in models derived from observed seismic data is a major issue. In this research we examine the geological structure of the sub-surface using controlled source seismology which gives the data in time and the distance between th...

One of the most important archaeological sites in Sudan is Meroe, capital city of the kingdom of Kush (800 bc to ad 400). The site is located in the Nile valley, about 200 km northeast of Khartoum. The most prominent feature among the ruins of Meroe... Read More about Magnetic Gradient and Electrical Resistivity Tomography Surveys in Meroe, the Capital City of the Kush Kingdom, Sudan.

Mapping turbidity layers using seismic oceanography methods (2012)

Using a combination of seismic oceanographic and physical oceanographic data acquired across the Faroe-Shetland Channel we present evidence of a turbidity layer that transports suspended sediment along the western boundary of the Channel. We focus on... Read More about Mapping turbidity layers using seismic oceanography methods.

Estimating Geostrophic Shear from Seismic Images of Oceanic Structure (2011)
Journal Article
Sheen, K. L., White, N., Caulfield, C. P., & Hobbs, R. W. (2011). Estimating Geostrophic Shear from Seismic Images of Oceanic Structure. Journal of Atmospheric and Oceanic Technology, 28(9), 1149-1154. https://doi.org/10.1175/jtech-d-10-05012.1

It is shown that geostrophic vertical shear estimates can be recovered from seismic (i.e., acoustic) images of thermohaline structure. In the Southern Ocean, the Antarctic Circumpolar Current forms a loop within the Falkland Trough before it flows no...

Vintage 2-D (two-dimensional) seismic reflection surveys from the sparsely explored Mentelle Basin (western Australian margin) have been reprocessed and integrated with a recent high-quality 2-D seismic survey and stratigraphic borehole data. Interpr... Read More about Re-evaluation of the Mentelle Basin, a polyphase rifted margin basin, offshore southwest Australia: new insights from integrated regional seismic datasets.

Improving the interpretability of air-gun seismic reflection data using deterministic filters: A case history from offshore Cape Leeuwin, south-west Australia (2011)
Journal Article

To identify drilling targets for an Integrated Ocean Drilling Program project to investigate high-latitude black shales required reinterpretation of legacy seismic data. The original processing had identified the major structures but was of insuffici...

Some improvements in subbasalt imaging using pre-stack depth migration (2011)
Journal Article

Subbasalt imaging can be improved by carefully applying pre-stack depth migration. Pre-stack depth migration requires a detailed velocity model and an accurate traveltime calculation. Ray tracing methods are fast but, often fail in calculating travel... Read More about Some improvements in subbasalt imaging using pre-stack depth migration.
