A springtime source of toxic Pseudo-nitzschia cells on razor clam beaches in the Pacific Northwest

Creator:: Hickey, Barbara M., Trainer, Vera L., Kosro, P. Michael, Adams, Nicolaus G., Connolly, Thomas P., Kachel, Nancy B., and Geier, Susan L.
Abstract:: Concentrations of domoic acid (DA) above the regulatory limit in Washington coast razor clams are usually higher on northern beaches from summer to fall. Recent field studies have confirmed that the primary source of toxic Pseudo-nitzschia (PN) cells in those seasons is a semi-retentive topographically trapped seasonal eddy located offshore...

Global climate evolution during the last deglaciation

Creator:: Clark, Peter U., Shakun, Jeremy D., Baker, Paul A., Bartlein, Patrick J., Brewer, Simon, Brook, Edward J., Carlson, Anders E., Cheng, Hai, Kaufman, Darrell S., Liu, Zhengyu, Marchitto, Thomas M., Mix, Alan C., Morrill, Carrie, Otto-Bliesner, Bette L., Pahnke, Katharina, Russell, James M., Whitlock, Cathy, Adkins, Jess F., Blois, Jessica L., Clark, Jorie, Colman, Steven M., Curry, William B., Flower, Ben P., He, Feng, Johnson, Thomas C., Lynch-Stieglitz, Jean, Markgraf, Vera, McManus, Jerry, Mitrovica, Jerry X., Moreno, Patricio I., and Williams, John W.
Abstract:: Deciphering the evolution of global climate from the end of the Last Glacial Maximum approximately 19 ka to the early Holocene 11 ka presents an outstanding opportunity for understanding the transient response of Earth's climate system to external and internal forcings. During this interval of global warming, the decay of...

Community Responses to Climate-Related Variability and Disease: The Critical Importance of Long-Term Research

Creator:: Menge, Bruce A., Caselle, Jennifer E., Barth, John A., Blanchette, Carol A., Carr, Mark H., Chan, Francis, Gravem, Sarah, Gouhier, Tarik C., Lubchenco, Jane, McManus, Margaret A., Milligan, Kristen, Novak, Mark, Raimondi, Peter T., Washburn, Libe, and White, J. Wilson
Abstract:: A major goal of the Partnership for Interdisciplinary Studies of Coastal Oceans (PISCO) has been to understand the impacts of climate change and variability on the coastal ecosystems of the inner shelf of the California Current Large Marine System in particular, and other marine and even nonmarine systems more generally....

New Insights on the Southern Ocean Carbon Cycle from Biogeochemical Argo Floats

Creator:: Williams, Nancy L.
Abstract:: The Southern Ocean plays an important role in the ocean’s uptake of heat and carbon yet the processes controlling this uptake are not well understood. To date, more than 100 biogeochemical profiling floats that measure water column pH, oxygen, nitrate, fluorescence, and backscattering at 10-day intervals have been deployed throughout...

Diversity, Generalization, and Specialization in Plant-Pollinator Networks of Montane Meadows, Western Cascades, Oregon

Creator:: Helderop, Edward
Abstract:: Despite the importance of plant-pollinator interactions for ecological communities, few long-term observational studies have been conducted of plant-pollinator networks. Using four years of plant-pollinator interaction data from 18 meadows in the Willamette National Forest, Oregon, this thesis examined how meadow size, the amount of nearby meadow habitat, weather, degree days,...

Tidal-band and high-frequency internal variability on the central Oregon inner shelf

Creator:: Suanda, Sutara H.
Abstract:: Analogous to ocean surface waves, waves in the ocean interior also experience steepening, breaking, and dissipation as they approach the coastline. Much less is known about this internal beach. In this work, extensive moored Acoustic Doppler Current Profiler and temperature/salinity data together with optical remote sensing are combined to describe...

The Geology, Geochronology, and Geochemistry of the Miocene Volcanic Rocks at the Inmaculada Ag-Au Mine, Southern Peru

Creator:: Cuellar Quispe, Juan Carlos
Abstract:: The Inmaculada Mine is located in the Miocene belt of epithermal deposits that extends from southern Peru to northern Chile and Bolivia. This belt is known for its silver-rich epithermal veins that have been worked since colonial times. The Inmaculada Mine belongs to a mining district that includes, from north...

Incorporating the Impacts of Climate Variability on Growth in Fish Population Dynamics Models

Creator:: Moron Correa, Giancarlo Helar
Abstract:: Variations in ocean conditions influenced by climate fluctuations may impact fish populations by changing their spatial distribution, physiology, survival, and other ecological features. Somatic growth is a crucial aspect of the biology of fishes and an important contributor to biomass fluctuations. Climate variability also affects somatic growth rates along the...

Using GIS to illustrate the geospatial and socio-ecological intersection between climate change, energy production, and sustainable fisheries management in Oregon

Creator:: Cohn, Leanne A.
Abstract:: There could be a geospatial and socio-ecological intersection between climate change, energy production, and sustainable fisheries management in the United States. Marine renewable energy generation efforts are currently being planned, studied, and initially implemented in the country as a response to climate change. The Bureau of Ocean Energy Management is...

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...
