Abstract:

The mass of carbon trapped in methane hydrates exceeds that in conventional fossil fuel reservoirs. While methane in coarse-grained hydrate-bearing sediments is technically recoverable, most methane hydrates are found in fine-grained marine sediments where gas recovery is inherently impeded by very low gas permeability. Using experimental methods and analyses, this thesis advances the understanding of fine-grained sediments in view of gas production from methane hydrates. The research scope includes: a new approach for the classification of fines in terms of electrical sensitivity, the estimat

Abstract:

Sediments in the Trinity River were chemically, physically and biologically characterized and assessed for toxicity. Laboratory bioassays were conducted to identify sediments which induced toxic responses in test organisms and to document these responses through time. Metal and organic contaminant concentrations in bottom sediments were measured. Relationships between these concentrations and biological responses observed in laboratory bioassays were determined. Toxicity identification / reduction methods were used to characterize sediment toxicants. Sediment oxygen demand was also measured in

Abstract:

The amount of carbon trapped in hydrates is estimated to be larger than in conventional oil and gas reservoirs, thus methane hydrate is a promising energy resource. The high water pressure and the relatively low temperature needed for hydrate stability restrict the distribution of methane hydrates to continental shelves and permafrost regions. Stability conditions add inherent complexity to coring, sampling, handling, testing and data interpretation, and have profound implications on potential production strategies. New guidelines are identified for sampling equipment and protocols. Then a nov

Abstract:

An extensive amount of natural gas trapped in the subsurface is found as methane hydrate. A fundamental understanding of natural hydrate-bearing sediments is required to engineer production strategies and to assess the risks hydrates pose to global climate change and large-scale seafloor destabilization. This thesis reports fundamental studies on hydrate nucleation, morphology and the evolution of unsaturation during dissociation, followed by additional studies on sampling and pressure core testing. Hydrate nucleation is favored on mineral surfaces and it is often triggered by mechanical vibra

For this reason this work has been focused also on possible impacts of the landfill on the groundwaters (shallow and deep aquifer).

On August 29, 2005 Hurricane Katrina struck the Gulf Coast and storm surges breached levees flooding much of New Orleans, Louisiana. One month after the storm, sediment was collected and toxicity was tested using Japanese medaka (Oryzias latipes) embryos. Sediments with the highest contaminant levels showed the highest embryonic mortality and most delayed development. However, no sediment caused an increased mutant frequency. When the most contaminated site was resampled in February, 2006 contaminant levels and toxicity decreased. During toxicity testing, approximately 20% of embryos incubated

Abstract:

The behavior of U in near surface sedimentary environments has changed throughout geologic time. There is a marked shift in U (IV) mineral stability and deposit style at approximately 2200 Ma due to changes in the concentration of O in the atmosphere. For example, prior to 2200 Ma, fluvial U deposits could form and U(IV) were stable in surface and near-surface environments. In modern, anthropogenic sedimentary systems such as U tailings, U (IV) minerals are not stable and readily oxidize to U (VI) minerals. In addition, U is much more mobile in modern sediments relative sediments that were

The long-term fate of hydrocarbons in the Gulf of Mexico (GOMx) following the 2010 Deepwater Horizon oil spill has yet to be fully characterized.

Abstract:

Conselho Nacional de Desenvolvimento CientÃfico e TecnolÃgico<br>This work aims to present an analysis through the experiments driven in a watershed to support the future studies that point out to identification and checking the causes that promote the degradation in the semiarid region of the Northeast of Brazil. It was taken two watershed cited in the Escola AgrotÃcnica Federal de Iguatu â EAFIGT located in the Iguatu County, CearÃ, Brazil, It was made the morphometrical characterization, the identification of the vegetation (herbaceous and arboreal) substrates and the evaluation of the sedi

Abstract:

In-situ geotechnical testing of surficial sediment layers in areas of active sediment dynamics can provide essential information about physical and geotechnical variations of sediment properties with regards to active sediment remobilization processes. For example, portable free fall penetrometers (PFFPs) can assist with the detection of mobile sediment layers. They are easy to deploy, and can provide a large spatial coverage in a time- and cost-effective manner. However, they often struggle to provide more detailed information about the properties of mobile sediment layers due to a lack of ca
