Modeling Eddy Correlation Biases Created by Velocity Sensitivities of Clark-type Oxygen Microelectrodes Under Waves

Creator:: Albright, Andrea and Albright, Andrea T. P.
Abstract:: Field deployments, flume experiments, and a 2D wave model have been used to identify the characteristics of Clark-type oxygen microelectrodes and measurement parameters that could possibly bias eddy correlation (EC) flux measurements made under waves. Eddy correlation is a technique adapted from atmospheric sciences that couples concurrent and co-located velocity...

Toward biologically meaningful net carbon exchange estimates for tall, dense canopies: Multi-level eddy covariance observations and canopy coupling regimes in a mature Douglas-fir forest in Oregon

Creator:: Thomas, Christoph K., Martin, Jonathan G., Law, Beverly E., and Davis, Kent
Abstract:: We sought to improve net ecosystem exchange (NEE) estimates for a tall, dense, mature Douglas-Fir forest in the Oregon Coast range characterized by weak flows, systematic wind directional shear, and limited turbulent mixing throughout the diurnal period. We used eddy covariance (EC) observations at two levels and concurrent biological measurements...

Impact of Igneous Mineralogy on the Composition and Metabolic Function of Microbial Biofilms in a Thermal Suboceanic Crustal Aquifer

Creator:: Smith, Amy R.
Abstract:: Igneous oceanic crust encompasses ~60% of Earth’s surface and is composed of basalt glass and mafic, ultramafic, and felsic minerals. A vast marine aquifer lies within the crust, exchanging geochemically altered fluids with seawater from the overlying ocean at ridge crests, flanks, seamounts, and outcrops where permeable crust is exposed....

Forest Fire Effects on Radiative and Turbulent Fluxes over Snow : Implications for Snow Hydrology

Creator:: Gleason, Kelly E.
Abstract:: As a result of a warming climate, subsequent declining snowpack, and a century of fire suppression, forest fires are increasing across the western United States. However, we still do not fully understand how forest fire effects snowpack energy balance, nor the volume and availability of snow melt and associated water...

Establishing interest in and understanding of the marine environment : an educational and cooperative approach utilizing an open source CTD

Creator:: Black, Ian
Abstract:: A number of groups in the United States have expressed concern regarding the state of public ocean literacy and the capabilities of the future marine STEM workforce. This pilot study explores some of the requirements for workforce development and the expansion of ocean literacy by introduction of fundamental ocean properties...

Influence of spatial and temporal factors on plants, pollinators and plant-pollinator interactions in montane meadows of the western Cascades Range

Creator:: Pfeiffer, Vera W.
Abstract:: Montane meadows comprise less than 5% of the landscape of the western Cascades of Oregon, but they provide habitat for diverse species of plants and pollinators. Little is known about plant-pollinator network structure at these sites. This study quantified plant-pollinator interactions over the summer of 2011, based on six observations...

New Insights into Mantle Dynamics from Helium Isotopes and Argon Geochronology

Creator:: Konrad, Kevin
Abstract:: Earth’s mantle extends to nearly 3000 km depth, comprises >80 % of Earth’s total volume, and has the largest influence on the primordial and radiogenic heat budget. Despite its importance, the structure and composition of the mantle is still debated. There are three primary models for Earth’s mantle structure that...

A field comparison of multiple techniques to quantify groundwater–surface-water interactions

Creator:: González-Pinzón, Ricardo, Ward, Adam S., Hatch, Christine E., Wlostowski, Adam N., Singha, Kamini, Gooseff, Michael N., Haggerty, Roy, Harvey, Judson W., Cirpka, Olaf A., and Brock, James T.
Abstract:: Groundwater–surface-water (GW-SW) interactions in streams are difficult to quantify because of heterogeneity in hydraulic and reactive processes across a range of spatial and temporal scales. The challenge of quantifying these interactions has led to the development of several techniques, from centimeter-scale probes to whole-system tracers, including chemical, thermal, and electrical...

San Juan Island National Historical Park Natural Resource Condition Assessment

Creator:: Adamus, Paul R.
Abstract:: We compiled existing data and information to characterize the condition and trends in high priority natural resources in San Juan Island National Historical Park. We identified 37 indicators to evaluate the condition and trend of these resources. For each indicator we attempted to define reference conditions to which we could...

Noble gases and coupled heat/fluid flow modeling for evaluating hydrogeologic conditions of volcanic island aquifers

Creator:: Heilweil, Victor M., Healy, Richard W., and Harris, Robert N.
Abstract:: Understanding groundwater conditions in the upland parts of volcanic island aquifers is critical for sustainable groundwater development in these resource-limited environments. Yet groundwater conditions in such settings are generally difficult to characterize because of sparse well drilling (high cost and/or limited access). Information needed for resource evaluation includes upland depth...
