The geochemical partitioning and bioavailability of trace metals in marine sediments

Creator:: Oakley, Stewart M.
Abstract:: Trace metals in the aquatic environment are generally concentrated on the surface of solid geochemical phases which eventually become incorporated into estuarine and marine sediments. The mechanism of trace metal concentration is believed to be adsorption with various geochemical phases such as hydrous metal oxides, clays, and organic matter. Metals...

Effects of pressure and deposit thickness on the stabilization rate of benthic marine sludge deposits

Creator:: Muellenhoff, W. P.
Abstract:: The biochemical degradation of domestic sludge deposits exposed to benthic marine conditions was investigated using a laboratory Deep Sea Simulator. The rate and extent of deposit stabilization were determined for select hydrostatic pressures and hydrogen acceptor conditions by monitoring depletion of particulate organic carbon in 2.0 and 3.0 centimeter deposits....

Radar and Optical Remote Sensing of Submesoscale Frontal Features

Creator:: Simpson, Alexandra J.
Abstract:: The coastal region is home to many types of surface fronts that exist on a submesoscale (1-10 $km$). While in situ observations capture point or transect observations of frontal behavior subsurface, their complex spatial patterns can be well-captured using remote sensing techniques, which provide synoptic views of the ocean surface...

New Techniques to Monitor and Characterize Landslide Behavior and Controls Using Digital Terrain Models

Creator:: Senogles, Andrew
Abstract:: Coastal landslides and erosion are major natural hazards resulting in unstable slopes, constituting immense challenges to modern infrastructure. Developing, maintaining, and performing risk assessments of infrastructure on, or close to, these hazards require a detailed understanding of the geophysical processes destabilizing the slope. These efforts start with the collection of...

Blast-induced liquefaction : observational estimation of vibration, settlement and residual pore water pressure

Creator:: Kato, Kengo
Abstract:: The blast technique has been used as an effective soil improvement method to compact loose coarse-granular soils since 1930s, and the use of the blast technique is extended as an application of in-situ liquefaction testing to investigate the performance of full scale foundations and countermeasures against liquefaction in recent decades....

Factors controlling halogenated and nonhalogenated alkene growth substrate range of vinyl chloride-utilizing bacteria

Creator:: Taylor, Anne Elizabeth
Abstract:: This thesis explores the factors limiting the alkene substrate range of the vinyl chloride (VC)-utilizing bacteria, and describes a method for measuring VC transformation in situ. Vinyl fluoride (VF) was evaluated as a surrogate for monitoring aerobic VC-transformation utilizing three isolates, Mycobacterium EE13a, Mycobacterium JS60 and Nocardioides JS614. JS614 grew...

Influence of silt size and content on static liquefaction potential of sand

Creator:: Monkul, M. Murat
Abstract:: Different specimen preparation methods such as moist tamping, dry funnel deposition, slurry deposition, dry air pluviation have been reported in the literature to investigate the undrained behavior of silty sands. Similarly, different means have been used to densify the soils prepared with such methods. However, the influence of the densification...

Electron donor and chlorinated ethene effects on activity and community composition in anaerobic reductively dechlorinating consortia

Creator:: Sabalowsky, Andrew R.
Abstract:: This research focused on anaerobic transformation of trichloroethene (TCE), a groundwater contaminant. The mixed anaerobic Evanite culture (EV) was studied to determine community behavior and composition responses to different electron donors and chloroethene electron acceptors. The potential toxicity from high concentrations of TCE and its daughter product cis-1,2-dichloroethene (cDCE) was...

Use of Controlled Blasting to Quantify the Dynamic, In-Situ, Nonlinear Inelastic Response of Soils

Creator:: Jana, Amalesh
Abstract:: The seismic response of deep deposits of liquefiable and cyclic-softening susceptible soils has presented the geotechnical profession with significant engineering challenges. Strong ground motions may serve to soften soils under cyclic shear, trigger liquefaction, and produce damaging displacements as a consequence. This study improves the understanding of the in-situ, nonlinear,...

Evaluation and application of ice segregation parameters for frost heave prediction

Creator:: Ito, Yuzuru, 1958-
Abstract:: The success of civil engineering construction in cold regions often depends on the assessment of the potential for frost heave. Over the past two decades two models have been presented to the engineering community to identify the frost heave potential, namely: (1) the segregation potential (SP), and (2) the discrete...
