During 2000-2001, the U.S. Geological Survey (USGS), in cooperation with the Ocean Modeling and Prediction Division of the U.S. Naval Oceanographic Office (NAVOCEANO), constructed tidal gages at the East Pearl River at CSX Railroad near Claiborne, Mississippi, at the Rigolets at CSX Railroad near Rigolets, Louisiana, and at the Chef Menteur Pass at CSX Railroad at Chef Menteur, Louisiana, to co...

Atmospheric carbon dioxide (CO2) data for the last 420 million years (My) show long-term fluctuations related to supercontinent cycles as well as shorter cycles at 26 to 32 My whose origin is unknown. Periodicities of 26 to 30 My occur in diverse geological phenomena including mass extinctions, flood basalt volcanism, ocean anoxic events, deposition of massive evaporites, sequence boundaries, a...

Again this year, abstracts from the annual Atlantic Universities Geological Conference (AUGC) are published in Atlantic Geology. This provides a permanent record of the abstracts, and also focuses attention on the excellent quality of the presentations and posters and the interesting and varied geoscience that they cover. The abstracts are published with fi nancial assistance from APICS. THE ED...

The laser-induced breakdown spectrometer (LIBS) on the ChemCam instrument [1] on the Curiosity rover on Mars has played a vital role in bringing this new technology to the attention of the scientific community. With over 100,000 spectra from individual laser shots collected to date and many more in progress, ChemCam has amply demonstrated the robustness of this technique for remote applications...

— The geological surveying presently uses methods and tools for the computer modeling of 3D-structures of the geographical subsurface and geotechnical characterization as well as the application of geoinformation systems for management and analysis of spatial data, and their cartographic presentation. The objectives of this paper are to present a 3D geological surface model of Latur district in...

In the past 10 years an abundance of new models aimed at finding a better or even the ultimate solution for the structure and evolution of the Mediterranean Tethys have been published. These models are based on new geophysical (mainly paleomagnetic) results, refined stratigraphic and facies data, and sometimes even on detailed geochemical analyses. They were constructed with the help of paleaog...

Hazard analysts and risk managers of natural perils, such as earthquakes, landslides and floods, need to access information from sensor networks surveying their regions of interest. However, currently information about these networks is difficult to obtain and is available in varying formats, thereby restricting accesses and consequently possibly leading to decision-making based on limited info...

Integrating geological concepts, such as relative positions and proportions of the different lithofacies, is of highest importance in order to render realistic geological patterns. The truncated plurigaussian simulation method provides a way of using both local and conceptual geological information to infer the distributions of the facies and then those of hydraulic parameters. The method (Le L...

The recent developments of training image-based geostatistics have allowed the creation of stochastic models with greater realism than before. These algorithms aim at reproducing spatial patterns, such as connectivity, that are depicted in a training image. A training image contains the possible spatial configurations for any given geological object and relationships between objects. However, a...
