Novel architecture for entrapment of elastomeric membranes in microfluidic systems

Creator:: Blackwell, Edward P.
Abstract:: This thesis presents a novel microlamination architecture that enables the large scale integration of valves into low cost micro energy and chemical systems via membrane entrapment. Polycarbonate layers embossed with microfluidic channels were bonded by ultrasonic welding of raised embossed protrusions that penetrate though the PDMS membranes. The bonding pressure...

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...

Subtidal inner-shelf circulation near Point Conception, California

Creator:: Cudaback, Cynthia N., Washburn, Libe, and Dever, Edward P.
Abstract:: We discuss connections between inner‐shelf and mid‐shelf circulation near Point Conception, California, as well as the wind forcing of inner‐shelf circulation. Point Conception marks the southern edge of a major upwelling zone that extends from Oregon to central California. The coastline makes a sharp eastward turn at Point Conception, and...

Abrupt changes in atmospheric methane at the MIS 5b–5a transition

Creator:: Grachev, Alexi M., Brook, Edward J., and Severinghaus, Jeffrey P.
Abstract:: New ice core analyses show that the prominent rise in atmospheric methane concentration at Dansgaard-Oeschger event 21 was interrupted by a century-long 20% decline, which was previously unrecognized. The reversal was found in a new ∼100-year resolution study of methane in the GISP2 ice core, encompassing the beginning of D-O...

Coastal Perturbations of Marine-Layer Winds, Wind Stress, and Wind Stress Curl along California and Baja California in June 1999

Creator:: Koracin, Darko, Dorman, Clive E., and Dever, Edward P.
Abstract:: Month-long simulations using the fifth-generation Pennsylvania State University–National Center for Atmospheric Research Mesoscale Model (MM5) with a horizontal resolution of 9 km have been used to investigate perturbations of topographically forced wind stress and wind stress curl during upwelling-favorable winds along the California and Baja California coasts during June 1999....

An evaluation of the thermal properties and albedo of a macrotidal flat

Creator:: Kim, Tae-Wan, Cho, Yang-Ki, and Dever, Edward P.
Abstract:: The thermal properties of sediment and the albedo are critical in calculating the heat flux of a tidal flat. However, they are not well known because of the difficulties of sampling and observing tidal flats. We use extensive field observations of a macrotidal flat on the western coast of Korea...

Characteristic patterns of shelf circulation at the boundary between central and southern California

Creator:: Winant, C. D., Dever, Edward P., and Hendershott, M. C.
Abstract:: The coastal circulation in the Santa Barbara Channel (SBC) and the southern central California shelf is described in terms of three characteristic flow patterns. The upwelling pattern consists of a prevailing equatorward flow at the surface and at 45 m depth, except in the area immediately adjacent to the mainland...

Evaluation of a coastal ocean circulation model for the Columbia River plume in summer 2004

Creator:: Liu, Yonggang, MacCready, Parker, Hickey, Barbara M., Dever, Edward P., Kosro, P. Michael, 1951-, and Banas, Neil S.
Abstract:: Realistic hindcast of the Columbia River estuarine-plume-shelf circulation in summer 2004 using the Regional Ocean Modeling System nested within the Navy Coastal Ocean Model (NCOM) is quantitatively evaluated with an extensive set of observations. The model has about equal skill at tidal and subtidal properties. Tidal circulation and water properties...

Relative timing and variability of atmospheric methane and GISP2 oxygen isotopes between 68 and 86 ka

Creator:: Grachev, Alexi M., Brook, Edward J., Severinghaus, Jeffrey P., and Pisias, Nicklas G.
Abstract:: The global biogeochemical cycle of methane has received wide attention because of methane's role as a greenhouse gas. Measurements of methane in air trapped in Greenland ice cores provide a high-resolution record of methane levels in the atmosphere over the past ~100 ka, providing clues about what controls the methane...

Three interacting freshwater plumes in the northern California Current System

Creator:: Hickey, B., McGabe, R., Geier, S., Dever, Edward P., and Kachel, N.
Abstract:: The northern California Current System is impacted by two primary freshwater sources: the Strait of Juan de Fuca and the Columbia River. The Columbia is frequently bidirectional in summer, with branches both north and south of the river mouth simultaneously. We describe the interaction of these two warm Columbia plumes...
