Coral-based climate reconstructions from a massive Porites coral from Sabine Bank (Vanuatu)
(2009-08)
A monthly resolved, 133 year record of coral Sr/Ca variations has been developed from a massive Porites coral that was drilled in the shallow waters of a submerged carbonate platform (Sabine Bank, 15.9°S, 166.14°E) located ...
Urban effects on groundwater recharge in Austin, Texas
(2004-05-22)
Cities and urban populations are growing at a high pace, but groundwater remains an underutilized resource in most urban areas. The general impacts of urban development on groundwater include overexploitation; subsidence; ...
Analyzing deep-water near seafloor geology with chirp sonar sub-bottom profiles : Green Canyon, Gulf of Mexico
(2006-12)
The study area is located on the continental slope in the Green Canyon deep-water area of the Gulf of Mexico. This area is being investigated by the Bureau of Economic Geology as part of several active gas hydrate studies ...
Hydrogeology of heterogeneous alluvium in the Leona aquifer, Caldwell County, Texas
(2005-05)
The Leona aquifer is an important, but overlooked, water resource in Central Texas. The Quaternary Leona Formation occurs as several isolated alluvial deposits at the margins of the Edwards Plateau. Each of these deposits ...
Azimuthal analysis of hybrid gathers
(2009-05)
The cross-spread formed by intersecting source and receiver lines, or “hybrid gather” consisting of all common mid-points (CMPs) in a reflection patch defined by the acquisition geometry, has been revived in recent years ...
Late Quaternary seismic stratigraphy and structure of the western insular shelf margin of Puerto Rico
(2006-05)
The modern insular shelf and slope of western Puerto Rico is characterized by reef carbonate and siliciclastic sedimentary environments controlled by the complex interplay of tectonic arching and faulting, vigorous erosion ...
Modeling reflux dolomitization
(2005)
The process of reflux dolomitization is commonly invoked to explain dolostone occurrence and distribution. The time required for this process to take place is not well understood. Volumetric flow rates are the dominant ...
Deep water Gulf of Mexico pore pressure estimation utilizing P-SV waves from multicomponent seismic in Atlantis Field
(2009-12)
Overpressure, or abnormally low effective pressures, is hazardous in drilling operations and construction of sea-bottom facilities in deepwater environments. Estimation of the locations of overpressure can improve safety ...
Tectonostratigraphic evolution of the northeastern Maturin foreland basin, Venezuela
(2009-08)
The study uses subsidence analysis of three deep wells to basement combined with sequence stratigraphic mapping to show that a 85,000 km² area of the Eastern Venezuelan foreland basin in the region of the Orinoco Delta ...
Using chemical data to define flow systems in Cuatro Cienegas, Coahuila, Mexico
(2005)
The Cuatro Cienegas basin in Coahuila, Mexico was declared a National Protected Area in 1994 by the Mexican government. Its principle uniqueness is in its aquatic fauna, which are dependent on the abundant springs in this ...
