We systematically incorporate burial history, sea floor geometry and tectonic loads from a sequential kinematic restoration model into 2D evolutionary geomechanical that simulates the formation of Sandia salt diapir, Tarfaya basin, NW African Coast. use poro-elastoplastic description for sediment behaviour viscoplastic salt. Sedimentation is coupled with flow regional shortening to determine po...

Geologic processes strongly influence water and sediment quality in aquatic ecosystems but rarely are geologic principles incorporated into routine biomonitoring studies. We test if elevated concentrations of metals in water and sediment are restricted to streams downstream of mines or areas that may discharge mine wastes. We surveyed 198 catchments classified as "historically mined" or "unmine...

Dynamic imaging provides an effective way to integrate previous time-lapse data with current data in order to estimate a current model. We present two methods useful for continuous dynamic reservoir and subsurface monitoring. The first method is a stochastic method for the inversion of geophysical data. It uses the ensemble Kalman filter (EnKF) that we demonstrate using time-lapse surface seism...

The CheMin instrument on the Mars Science Laboratory rover Curiosity detected ubiquitous high abundances (∼15–70 wt%) of X-ray amorphous components (AmCs) in ancient sedimentary rocks Gale crater. Mechanisms and timing formation for AmCs are poorly constrained, could include volcanic, impact, or aqueous processes. We explore trends AmC composition abundance, look systematic compositional variat...

REESE, C.A.; STRANGE, T.P.; LYNCH, W.D., and LIU, K.B., 2008. Geologic evidence of Hurricane Katrina recovered from the Pearl River Marsh, MS/LA. Journal of Coastal Research, 24(6), 1601–1607. West Palm Beach (Florida), ISSN 0749-0208. Hurricane Katrina made its final landfall on August 29, 2005, as a category three storm, at the mouth of the Pearl River on the Mississippi/Louisiana border. Bet...

[1] Small mountainous rivers (SMRs) export substantial amounts of sediment into the world’s oceans. The concomitant yield of organic carbon (OC) associated with this class of rivers has also been shown to be significant and compositionally unique. We report here excessively high loadings of polycyclic aromatic hydrocarbons (PAHs), lignin, and levoglucosan, discharged from the Santa Clara River ...
