On flames established with air jet in cross flow of fuel-rich combustion products

Creator:: Katta, Viswanath R., Blunck, David L., Jiang, Naibo, Lynch, Amy, Gord, James R., and Roy, Sukesh
Abstract:: Advances in combustor technologies are driving aircraft gas turbine engines to operate at higher pressures, temperatures and equivalence ratios. A viable approach for protecting the combustor from the high-temperature environment is to inject air through the holes drilled on the surfaces. However, it is possible that the air intended for...

Evidence for diffuse exension of the Pacific plate from Pukapuka ridges and cross-grain gravity lineations

Creator:: Sandwell, David T., Winterer, Edward L., Mammerickx, Jacqueline, Duncan, Robert A., Lynch, Mary Ann, Levitt, Daniel A., and Johnson, Catherine L.
Abstract:: Satellite altimeter measurements of marine gravity reveal 100 to 200-km wavelength lineations over a wide area of the Pacific plate oriented roughly in the direction of absolute plate motion. At least three mechanisms have been proposed for their origin: smallscale convective rolls aligned in the direction of absolute plate motion...

A New Look at Richardson Number Mixing Schemes for Equatorial Ocean Modeling

Creator:: Zaron, Edward D. and Moum, James N.
Abstract:: A reexamination of turbulence dissipation measurements from the equatorial Pacific shows that the turbulence diffusivities are not a simple function of the gradient Richardson number. A widely used mixing scheme, the K-profile parameterization, overpredicts the turbulent vertical heat flux by roughly a factor of 4 in the stably stratified region...

Dynamics of wind-driven upwelling and relaxation between Monterry Bay and Point Arena : local-, regional-, and gyre-scale controls

Creator:: Pringle, James M. and Dever, Edward P.
Abstract:: In north and central California, equatorward winds drive equatorward flows and the upwelling of cold dense water over the shelf during the midspring and summer upwelling season. When the winds temporarily weaken, the upwelling flows between Point Reyes and Point Arena ‘‘relax,’’ becoming strongly poleward over the shelf. Analytical and...

Global climate evolution during the last deglaciation

Creator:: Clark, Peter U., Shakun, Jeremy D., Baker, Paul A., Bartlein, Patrick J., Brewer, Simon, Brook, Edward J., Carlson, Anders E., Cheng, Hai, Kaufman, Darrell S., Liu, Zhengyu, Marchitto, Thomas M., Mix, Alan C., Morrill, Carrie, Otto-Bliesner, Bette L., Pahnke, Katharina, Russell, James M., Whitlock, Cathy, Adkins, Jess F., Blois, Jessica L., Clark, Jorie, Colman, Steven M., Curry, William B., Flower, Ben P., He, Feng, Johnson, Thomas C., Lynch-Stieglitz, Jean, Markgraf, Vera, McManus, Jerry, Mitrovica, Jerry X., Moreno, Patricio I., and Williams, John W.
Abstract:: Deciphering the evolution of global climate from the end of the Last Glacial Maximum approximately 19 ka to the early Holocene 11 ka presents an outstanding opportunity for understanding the transient response of Earth's climate system to external and internal forcings. During this interval of global warming, the decay of...

Shallow Water '06: A Joint Acoustic Propagation/Nonlinear Internal Wave Physics Experiment

Creator:: Tang, Dajun, Moum, James N., Lynch, James F., Abbot, Phil, Chapman, Ross, Dahl, Peter H., Duda, Timothy F., Gawarkiewicz, Glen, Glenn, Scott, Goff, John A., Graber, Hans, Kemp, John, Maffei, Andrew, Nash, Jonathan D., and Newhall, Arthur
Abstract:: Since the end of the Cold War, the US Navy has had an increasing interest in continental shelves and slopes as operational areas. To work in such areas requires a good understanding of ocean acoustics, coastal physical oceanography, and, in the modern era, autonomous underwater vehicle (AUV) operations. Each area...

Form Drag and Mixing Due to Tidal Flow past a Sharp Point

Creator:: Edwards, Kathleen A., MacCready, Parker, Moum, James N., Pawla, Geno, Klymak, Jody M., and Perlin, Alexander
Abstract:: Barotropic tidal currents flowing over rough topography may be slowed by two bottom boundary–related processes: tangential stress of the bottom boundary layer, which is generally well represented by a quadratic drag law, and normal stress from bottom pressure, known as form drag. Form drag is rarely estimated from oceanic observations...

Constraints on the Late Holocene Anthropogenic Contribution to the Atmospheric Methane Budget

Creator:: Mitchell, Logan, Brook, Edward J., Lee, James E., Buizert, Christo, and Sowers, Todd
Abstract:: The origin of the late pre-industrial Holocene (LPIH) increase in atmospheric methane concentrations has been much debated. Hypotheses invoking changes in solely anthropogenic sources or solely natural sources have been proposed to explain the increase in concentrations. Here two high-resolution, high-precision ice core methane concentration records from Greenland and Antarctica...

Metabolism of Nonesterified and Esterified Hydroxycinnamic Acids in Red Wines by Brettanomyces bruxellensis

Creator:: Schopp, Lauren M., Lee, Jungmin, Osborne, James P., Chescheir, Stuart C., and Edwards, Charles G.
Abstract:: While Brettanomyces can metabolize nonesterified hydroxycinnamic acids found in grape musts/wines (caffeic, p-coumaric, and ferulic acids), it was not known whether this yeast could utilize the corresponding tartaric acid esters (caftaric, p-coutaric, and fertaric acids, respectively). Red wines from Washington and Oregon were inoculated with B. bruxellensis, while hydroxycinnamic acids...

Identification and Characterization of Human Cytomegalovirus-Encoded MicroRNAs

Creator:: Grey, Finn, Antoniewicz, Andy, Allen, Edwards, Saugstad, Julie, McShea, Andy, Carrington, James C., and Nelson, Jay
Abstract:: MicroRNAs (miRNAs) are an extensive class of noncoding genes that regulate gene expression through posttranscriptional repression. Given the potential for large viral genomes to encode these transcripts, we examined the human cytomegalovirus AD169 genome for miRNAs using a bioinformatics approach. We identified 406 potential stem-loops, of which 110 were conserved...
