Late Holocene climate: Natural or anthropogenic?

Creator:: Ruddiman, W. F., Fuller, D. Q., Kutzbach, J. E., Tzedakis, P. C., Kaplan, J. O., Ellis, E. C., Vavrus, S. J., Roberts, C. N., Fyfe, R., He, F., Lemmen, C., and Woodbridge, J.
Abstract:: For more than a decade, scientists have argued about the warmth of the current interglaciation. Was the warmth of the preindustrial late Holocene natural in origin, the result of orbital changes that had not yet driven the system into a new glacial state? Or was it in considerable degree the...

Effects of Anthropogenic Stressors on Seagrass and Coral Microbiomes

Creator:: Wang, Lu
Abstract:: Seagrasses and coral reefs play important roles in nutrient cycling, coastal protection, and maintaining marine biodiversity. However, these coastal marine organisms are declining globally due to anthropogenic stressors, such as rising ocean temperatures, ocean acidification, and eutrophication. These organisms live in close association with their microbiomes, which can be beneficial...

The Effects of Road Noise on Pacific Chorus Frog Communication

Creator:: Nelson, Danielle V.
Abstract:: Amphibians are experiencing global population declines and are one of the most threatened groups of vertebrates. This can be attributed to multiple environmental stressors such as habitat loss, disease, invasive species, and climate change. For vocal amphibian species, loss of acoustic habitat due to anthropogenic noise may be yet another...

Effects of jet aircraft overflights and other potential disturbances on behavioral responses and productivity of nesting peregrine falcons

Creator:: Nordmeyer, Dana L.
Abstract:: In order to examine the potential impact of military jet overflights and other disturbances on productivity of peregrine falcons (Falco peregrinus), we observed behavioral reactions of peregrines to disturbances at nests along the Tanana River, Alaska during the 1995-1997 breeding seasons. Military jets conducted low-altitude flights over a sample of...

Trans-Pacific and regional atmospheric transport of anthropogenic semivolatile organic compounds in the western U.S.

Creator:: Primbs, Toby
Abstract:: The atmospheric transport of anthropogenic semivolatile organic compounds (SOCs) from Asian sources to the Western U.S. was investigated. In addition, the SOC extraction method was optimized. Hansen solubility parameter plots were used to aid in the pressurized liquid extraction (PLE) solvent selection of air sampling media in order to minimize...

Assessment of Underwater Noise Generated by Wave Energy Devices

Creator:: Leary, Del, JASCO Applied Science, Ferguson, James, O'Neill, Caitlin, Austin, Melanie, Chorney, Nicole, and Sneddon, Holly
Abstract:: The potential for creating underwater noise disturbance is one environmental impact that must be accounted for by wave energy developers to meet the needs of regulatory agencies. This review study has been conducted to provide a concise knowledge base of the expected underwater noise conditions in the near shore environment...

Drowning in the noise : an examination of noise pollution’s effect on wild birds through field recording and musical composition

Creator:: Kruger-Moore, Liana
Abstract:: This project uses field recordings to examine the levels of noise pollution present in both rural and urban areas by creating an artistic translation of these soundscapes, representative of how wild birds experience different environments. The field recordings capture not only what is present in a given soundscape, but what...

Development and Calibration of a Sound Propagation Model for the Oregon Coast

Creator:: Küsel, Elizabeth T., Siderius, Martin, Sorenson, Eric, Klinck, Holger, and Mellinger, David K.
Abstract:: In this report we present results of a sound propagation modeling study off the coast of Newport, OR. Preliminary acoustic experimental data was also collected by an underwater glider equipped with a hydrophone to measure sound levels in a short transect perpendicular to the coast and away from a sound...

Anthropogenic CO₂ invasion into the northeast Pacific based on concurrent δ¹³CDIC and nutrient profiles from the California Current

Creator:: Ortiz, Joseph D., Mix, Alan C., Wheeler, Patricia A., and Key, R. M.
Abstract:: The stable isotopic signature of dissolved inorganic carbon (δ¹³CDIC) in the northeast Pacific Ocean is lower in near-surface waters by 1.1‰ relative to values predicted from global oceanic trends of δ¹³CDIC versus nutrients. A combination of anthropogenic carbon uptake from the atmosphere and thermodynamic, air-sea gas exchange processes in different...

Application of biomarker compounds as tracers for sources and fates of natural and anthropogenic organic matter in the environment

Creator:: Oros, Daniel R.
Abstract:: Determination of the source and fate of natural (higher plant lipids, marine lipids, etc.) and anthropogenically (e.g., petroleum, coal emissions) derived hydrocarbons and oxygenated compounds in the environment was accomplished using gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) to characterize or identify molecular biomarkers to be utilized as tracers....
