Two Advances in Practical Alternative Energy: Thermotolerant Hydrogenase Concentration and Methane Hydrate Grain Size Proxies.

Creator:: Sullivan, Nichole D.
Abstract:: Methane hydrates and biohydrogen are two disparate subjects that are of interest in the growing field of alternative energy research. However, before commercial use becomes a viable option, each has challenges that need to be overcome. Methane hydrates require large investments of time and capital to locate. In this thesis,...

Seismic sequence stratigraphy and tectonic evolution of southern hydrate ridge

Creator:: Chevallier, Johanna
Abstract:: A 3D seismic volume was acquired summer 2000 over the southern end of Hydrate Ridge (FIR), an anomalously shallow ridge 100 km offshore Newport, Oregon. The survey followed a succession of scientific expeditions aimed at studying the gas hydrates present in the shallow subsurface that gave the name to the...

The Gorda Escarpment's rise and fall : synthesis of exploration seismology, sampling efforts, micropaleontology, and radiometric dating

Creator:: Potter, Susan M.
Abstract:: The Gorda Escarpment (40.4° N and from 126° W to 124.7° W) is a topographic high which is the eastern portion of the Mendocino Transform Fault. The Vizcaino Block is the anomalously shallow portion of the Pacific plate immediately south of the Gorda Escarpment. Sediments of the Vizcaino Block record...

Subsurface temperatures beneath Southern Hydrate Ridge

Creator:: Tréhu, Anne Martine
Abstract:: During Ocean Drilling Program Leg 204, 80 in situ measurements of subseafloor temperature were made; 68 of these showed good frictional pulses on insertion and extraction from the seafloor and were used to constrain the subsurface temperature. Considering uncertainties from various sources, uncertainties in the in situ temperatures are estimated...

3-D seismic imaging of an active margin hydrate system, Oregon continental margin : report of cruise TTN 112 R/V Thomas Thompson, June 19 - July 3, 2000

Creator:: Tréhu, Anne Martine and Bangs, Nathan Lawrence Bailey
Abstract:: In the past several years, international interest in gas hydrates in marine sediments has increased considerably because of increasing recognition that the large volume of gas stored in hydrates or trapped beneath them is a significant fraction of the global methane budget, and may therefore be a source of energy...

Interactive fault localization techniques to empower the debugging efforts of end-user programmers

Creator:: Ruthruff, Joseph Ronald
Abstract:: End users develop more software than any other group of programmers, using software authoring devices such as e-mail filtering editors, by-demonstration macro builders, and spreadsheet environments. Despite this, there has been only a little research on finding ways to help these programmers with the dependability of the software they create....

Near-offset vertical seismic experiments during leg 204

Creator:: Tréhu, Anne Martine, Bangs, Nathan Lawrence Bailey, and Guerin, Gilles
Abstract:: Three successful vertical seismic profiles (VSPs) were acquired during Ocean Drilling Program (ODP) Leg 204 at South Hydrate Ridge. The data confirm earlier results from ocean bottom seismometer data and analysis of moveout from common midpoint reflection data that the average velocity between the seafloor and the bottom-simulating reflector (BSR)...

Leg 204 synthesis : gas hydrate distribution and dynamics in the Central Cascadia accretionary complex

Creator:: Tréhu, Anne Martine, Torres, Marta E., Bohrmann, G., and Colwell, Frederick
Abstract:: Ocean Drilling Program (ODP) Leg 204 to Hydrate Ridge, located on the continental slope offshore Oregon (USA), was the first drilling expedition dedicated to understanding gas hydrate processes in accretionary complexes and provided a testbed for a number of different techniques for estimating the gas hydrate content of sediments. It...

Upward shifts in the southern Hydrate Ridge gas hydrate stability zone following postglacial warming, offshore Oregon

Creator:: Bangs, Nathan Lawrence Bailey, Musgrave, Robert J., and Tréhu, Anne Martine
Abstract:: High‐resolution three‐dimensional (3‐D) seismic reflection data acquired on the R/V Thomas G. Thompson in 2000 reveal a pair of bottom simulating reflections (BSRs) across a broad region of southern Hydrate Ridge, offshore Oregon. The primary BSR (BSRp) is a regionally extensive reflection that lies 120–150 m below seafloor and exhibits...

Possible emplacement of crustal rocks into the forearc mantle of the Cascadia Subduction Zone

Creator:: Calvert, Andrew J., Fisher, Michael A., Ramachandran, Kumar, and Tréhu, Anne Martine
Abstract:: Seismic reflection profiles shot across the Cascadia forearc show that a 5–15 km thick band of reflections, previously interpreted as a lower crustal shear zone above the subducting Juan de Fuca plate, extends into the upper mantle of the North American plate, reaching depths of at least 50 km. In...
