Videographic and GPS techniques for monitoring active glacial surge: Bering Glacier, Alaska

Creator:: Thatcher, P. Anthony
Abstract:: Aerial videography in combination with GPS were used to monitor the active surge of Alaska's Bering Glacier. The large aerial extent of the study area and the unpredictable weather in coastal Alaska required innovative techniques to be used in order to successfully monitor the surge environment. A portable aerial videographic...

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...

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...

Fishery-specific solutions to seabird bycatch in the U.S. West Coast sablefish fishery

Creator:: Good, Thomas P., Jannot, Jason E., Melvin, Edward F., Gladics, Amanda J., Suryan, Robert M., and Guy, Troy J.
Abstract:: Bird scaring lines (BSLs) protect longline fishing gear from seabird attacks, save bait, reduce incidental seabird mortality and are the most commonly prescribed seabird bycatch mitigation measure worldwide. We collaborated with fishermen to assess the efficacy of applying BSL regulations from the demersal longline sablefish fishery in Alaska to a...

Connectivity among straits of the northwest Pacific marginal seas

Creator:: Cho, Yang-Ki, Seo, Gwang-Ho, Choi, Byoung-Ju, Kim, Sangil, Kim, Young-Gyu, Youn, Yong-Hoon, and Dever, Edward P.
Abstract:: The connectivity among straits of the northwest Pacific marginal seas is investigated with a primitive-equation ocean circulation model simulated for 10 years from 1994 to 2003. Over the simulation interval the temporal and spatial means and variations of the model sea surface temperature are comparable to those of the satellite...

Instruments and Methods: A novel method for obtaining very large ancient air samples from ablating glacial ice for analyses of methane radiocarbon

Creator:: Petrenko, Vasilii V., Severinghaus, Jeffrey P., Brook, Edward J., Muhle, Jens, Headly, Melissa, Harth, Christina M., Schaefer, Hinrich, Reeh, Niels, Weiss, Ray F., Lowe, Dave, and Smith, Andrew M.
Abstract:: We present techniques for obtaining large (∼100 L STP) samples of ancient air for analysis of ¹⁴C of methane (¹⁴CH₄) and other trace constituents. Paleoatmospheric ¹⁴CH₄ measurements should constrain the fossil fraction of past methane budgets, as well as provide a definitive test of methane clathrate involvement in large and...

Using the nitrogen mineralization soil test to predict spring fertilizer N rate for soft white winter wheat grown in western Oregon

Creator:: Anderson, Nicole P., Hart, John M. (John Mervyn), 1947-, Christensen, Neil Walter, 1944-, Mellbye, Mark Edward, Flowers, Michael Darrell, 1971-, and Oregon State University. Extension Service
Abstract:: Soft white winter wheat is grown in western Oregon and requires a spring application of nitrogen (N) fertilizer for optimum production. Determining the amount of N to apply has been a challenge for growers. Wheat obtains N from two sources: soil and fertilizer. Both available and mineralizable N can be...

Anomalous Near-Surface Low-Salinity Pulses off the Central Oregon Coast

Creator:: Mazzini, Piero L. F., Risien, Craig M., Barth, John A., Pierce, Stephen D., Erofeev, Anatoli, Dever, Edward P., Kosro, P. Michael, Levine, Murray D., Shearman, R. Kipp, and Vardaro, Michael F.
Abstract:: From mid-May to August 2011, extreme runoff in the Columbia River ranged from 14,000 to over 17,000 m³/s, more than two standard deviations above the mean for this period. The extreme runoff was the direct result of both melting of anomalously high snowpack and rainfall associated with the 2010–2011 La Niña....
