Multiple mantle plume components involved in the petrogenesis of subduction-related lavas from the northern termination of the Tonga Arc and northern Lau Basin: Evidence from the geochemistry of arc and backarc submarine volcanics

Creator:: Falloon, Trevor J., Danyushevsky, Leonid V., Crawford, Tony J., Maas, Roland, Woodhead, Jon D., Eggins, Stephen M., Bloomer, Sherman H., Wright, Dawn J., Zlobin, Sergei K., and Stacey, Andrew R.
Abstract:: New seafloor mapping and sampling demonstrates that the eruption of the high-Ca boninites is clearly associated with rifting of the northern Tonga ridge and the northern Lau Basin at the northern termination of the Tonga Trench. There is very strong evidence for OIB plume related mantle sources involved in the...

A Nonlinear Pseudoparabolic Diffusion Equation

Creator:: Böhm, Michael and Showalter, R. E.
Abstract:: Diffusion in a fissured medium with absorption or partial saturation effects leads to a pseudoparabolic equation nonlinear in both the enthalpy and the permeability. The corresponding initial-boundary value problem is shown to have a solution in various Sobolev-Besov spaces, and sufficient conditions are given for the problem to be well-posed.

Energy exchange studies at the earth's surface. II. Energy budget of a pumice desert

Creator:: Holbo, Harold Richard
Abstract:: The energy budget of a pumice desert surface was analyzed under clear skies during early, mid-and late summer periods. The pumice site is in the semi-arid plateau region of Central Oregon at an elevation of about 1500 meters. The flat pumice surface is approximately 250 hectares in extent, and is...

Seasonal flows of international British Columbia-Alaska rivers: The nonlinear influence of ocean-atmosphere circulation patterns

Creator:: Fleming, S. W., Hood, E., Dahlke, H. E., and O'Neel, S.
Abstract:: The northern portion of the Pacific coastal temperate rainforest (PCTR) is one of the least anthropogenically modified regions on earth and remains in many respects a frontier area to science. Rivers crossing the northern PCTR, which is also an international boundary region between British Columbia, Canada and Alaska, USA, deliver...

Crustal inheritance and a top-down control on arc magmatism at Mount St. Helens

Creator:: Bedrosian, Paul A., Peacock, Jared R., Bowles-Martinez, Esteban, Schultz, Adam, and Hill, Graham
Abstract:: In a subduction zone, the volcanic arc marks the location where magma, generated via flux melting in the mantle wedge, migrates through the crust and erupts. While the location of deep magma broadly defines the arc position, here we argue that crustal structures, identified in geophysical data from the Washington...

Small-Scale Processes in the Coastal Ocean

Creator:: Moum, James N., Nash, Jonathan D., and Klymak, Jody M.
Abstract:: Varied observations over Oregon’s continental shelf illustrate the beauty and complexity of geophysical flows in coastal waters. Rapid, creative, and sometimes fortuitous sampling from ships and moorings has allowed detailed looks at boundary layer processes, internal waves (some extremely nonlinear), and coastal currents, including how they interact. These processes drive...

Five years of carbon fluxes and inherent water-use efficiency at two semi-arid pine forests with different disturbance histories

Creator:: Vickers, Dean, Thomas, Christoph K., Pettijohn, Cory, Martin, Jon G., and Law, Beverly E.
Abstract:: Five years of eddy-covariance and other measurements at a mature ponderosa pine forest and a nearby young plantation are used to contrast the carbon fluxes for long-term averages, seasonal patterns, diel patterns and interannual variability, and to examine the differing responses to water-stress. The mature forest with larger leaf area...

Intraplate seamounts as a window into deep earth processes

Creator:: Koppers, Anthony A. P. and Watts, Anthony B.
Abstract:: Seamounts are windows into the deep Earth that are helping to elucidate various deep Earth processes. For example, thermal and mechanical properties of oceanic lithosphere can be determined from the flexing of oceanic crust caused by the growth of seamounts on top of it. Seamount trails also are excellent recorders...

Observations of Broadband Acoustic Backscattering From Nonlinear Internal Waves: Assessing the Contribution From Microstructure

Creator:: Lavery, Andone C., Chu, Dezhang, and Moum, James N.
Abstract:: In this paper, measurements of high-frequency broadband (160–590 kHz) acoustic backscattering from surface trapped nonlinear internal waves of depression are presented. These waves are ideal for assessing the contribution from oceanic microstructure to scattering as they are intensely turbulent. Almost coincident direct microstructure measurements were performed and zooplankton community structure...
