Assessment of diffusive isotopic fractionation in polar firn, and application to ice core trace gas records

Creator:: Buizert, Christo, Sowers, Todd, and Blunier, Thomas
Abstract:: During rapid variations of the atmospheric mixing ratio of a trace gas, diffusive transport in the porous firn layer atop ice sheets and glaciers alters the isotopic composition of that gas relative to the overlying atmosphere. Records of past atmospheric trace gas isotopic composition from ice cores and firn need...

Capitalizing on Oregon’s Offshore Freshwater Bounty REnewable Food Energy Water on Land and Sea (REFEWLS)

Creator:: Blessing, Jacob M.
Abstract:: REFEWLS - REnewable Food Energy Water on Land and Sea Nexus This project will explore the connections between food, energy, and water uses along Oregon's mid coastal regions with a emphasis and focus on Newport. On average Newport uses approximately 2,000,000 gallons of water per day, but in the tourist...

Flow From Flexibility : Identifying Opportunities For Streamflow Restoration in a Transboundary Municipal Watershed Through Water Budgeting

Creator:: Pierson, Jessica S.
Abstract:: Municipal watersheds attempt to balance growing and conflicting demands for water for human use and for ecosystems. The Mill Creek basin, a 295 km2 basin in southeast Washington, exemplifies these conflicts. Since the late 1800s, the City of Walla Walla has withdrawn water from Mill Creek for municipal use. However,...

The WAIS Divide deep ice core WD2014 chronology – Part 1: Methane synchronization (68–31 kaBP) and the gas age–ice age difference

Creator:: Buizert, C., Cuffey, K. M., Severinghaus, J. P., Baggenstos, D., Fudge, T. J., Steig, E. J., Markle, B. R., Winstrup, M., Rhodes, R. H., Brook, Edward J., Sowers, T. A., Clow, G. D., Cheng, H., Edwards, R. L., Sigl, M., McConnell, J. R., and Taylor, K. C.
Abstract:: The West Antarctic Ice Sheet Divide (WAIS Divide, WD) ice core is a newly drilled, high-accumulation deep ice core that provides Antarctic climate records of the past ~68 ka at unprecedented temporal resolution. The upper 2850 m (back to 31.2 ka BP) have been dated using annual-layer counting. Here we...

Understanding Signals of the South Pole Ice Core: Chronology, Climate, and Firn Processes

Creator:: Epifanio, Jenna A.
Abstract:: The South Pole ice core (SPC14), drilled in the field seasons of 2014/2015 and 2015/2016, is an intermediate length, 1,751-m ice core which preserves a 54,000-year record of past climate and atmospheric composition. The SPC14 ice core adds to the spatial grid of ice cores in Antarctica extending into the...

International river basin management in the face of change : Syr Darya Basin case study

Creator:: Pak, Mariya
Abstract:: The conflict over water resources exploitation and sharing in the Aral Sea Basin is one of the most pressing environmental issues yet to be resolved in Central Asia. The fall of the Soviet Union in 1991 and establishment of the New Independent States (NIS) within the Aral Sea Bain led...

Anomalous porosity preservation and preferential accumulation of gas hydrate in the Andaman accretionary wedge, NGHP-01 site 17A

Creator:: Rose, Kelly K., Johnson, Joel E., Torres, Marta E., Hong, Wei-Li, Giosan, Liviu, Solomon, Evan A., Kastner, Miriam, Cawthern, Thomas, Long, Philip E., and Schaef, H. Todd
Abstract:: In addition to well established properties that control the presence or absence of the hydrate stability zone, such as pressure, temperature, and salinity, additional parameters appear to influence the concentration of gas hydrate in host sediments. The stratigraphic record at Site 17A in the Andaman Sea, eastern Indian Ocean, illustrates...

Influence of upwelling-season coastal currents on near-bottom dissolved oxygen concentrations over a submarine bank

Creator:: Adams, Katherine A.
Abstract:: Wind-driven coastal upwelling brings subsurface water onto the central-Oregon shelf after the spring transition each year. This cold and salty source water is oxygen-poor, yet above the hypoxic threshold, dissolved oxygen < 1.4 ml l⁻¹. Once on the shelf, dissolved oxygen (DO) concentrations of upwelled near-bottom waters are modified by...

The effect of river discharge and wind forcing on the Oregon coastal ocean during fall and winter

Creator:: Mazzini, Piero Luigi Fernandes
Abstract:: Freshwater provided from river discharge influences the dynamics and circulation of most continental shelves around the world. It has profound effects on the transport and fate of materials and substances originated from rivers and estuaries, as well as on the ocean biogeochemistry and marine ecosystems. The effect of buoyancy forcing...

It Depends: Defining Cooperation and Evaluating Effectiveness in Transboundary Waters

Creator:: McCracken, Melissa J.
Abstract:: With the increasing international focus on transboundary cooperation as a part of the Sustainable Development Goal (SDG) Framework, there is global recognition of transboundary water cooperation as a tool for improved governance and management of transboundary surface and groundwaters. Yet, there is not an agreed upon definition of transboundary water...
