Late pleistocene changes in the Peru current based on planktonic foraminifera

Creator:: Feldberg, Melissa J.
Abstract:: Planktonic foraminiferal faunal assemblages were used to estimate sea-surface temperatures (SST) in the southeast Pacific Ocean during the Last Glacial Maximum (LGM) and off the coast of Peru over the last 150,000 years. Temperatures along the eastern boundary of South America were 6-8° C cooler during the LGM than at...

Exploring the potential for using deep-sea bamboo corals (Isidella sp.) for paleoceanographic reconstructions

Creator:: Hornung, Jonathan P.
Abstract:: Deep-sea bamboo coral (Isidella sp.) SE000901A from the southern Oregon coast (water depth 1048m) provides a high-resolution record of variability of North Pacific Intermediate Water (NPIW) and carbon rain to the sea floor, related to coastal upwelling, from 1808 to 2000AD. Counting of annual layers in magnesium to calcium (Mg/Ca)...

Foraminiferal assemblages preserved in surface sediments correspond to multiple environmental and preservation variables

Creator:: Ross, Ann E. Morey
Abstract:: Here we investigate the relationships between modern foraminiferal assemblages from Atlantic and Pacific surface sediment samples and multiple environmental properties including water column and preservation variables using Canonical Correspondence Analysis (CCA). CCA finds two fauna] dimensions that are highly correlated to the environmental variables included in the analysis, and then...

Enhancing Small Sample Foraminifera Analysis through Innovative Mass Spectrometry Techniques: A Pathway to Deeper Paleoceanographic Insights

Creator:: Meyer, Grace
Abstract:: Stable oxygen and stable carbon isotopes of foraminifera are widely applied in paleoceanographic reconstructions. Oxygen and carbon isotopes are typically measured using pooled sample analysis (i.e., the combination of several shells) or single-shell analysis (typically restricted to heavier shells that weigh above 10 µg). With pooled sample analysis, where many...

Determination of unsaturation-, growth phase-, and growth rate-dependent hydrogen isotopic fractionation in C₃₇ alkenones produced by Emiliania huxleyi

Creator:: Wolhowe, Matthew D.
Abstract:: Recent works have investigated use of the hydrogen isotopic composition of C₃₇ alkenones (δD[subscript K37s]), lipid biomarkers of certain haptophyte microalgae, as an independent paleosalinity proxy. I discuss herein the factors impeding such an application and identify the potential alternative use of δD[subscript K37s] measurements as a proxy for non-thermal,...

Glacial to holocene watermass and continental weathering reconstructions from the Southeast Pacific

Creator:: Muratli, Jesse M.
Abstract:: Sediments of the central Chile margin record changes in ocean circulation and continental erosion associated with large–scale climate change. Here Antarctic– influenced Southern Ocean currents flow equatorward, forming a link between the high– and low–latitude oceans. Part of this link, Antarctic Intermediate Water, is an important conduit that ventilates South...

Using stable-isotope analysis to obtain dietary profiles from old hair

Creator:: Roy, Diana Milantia
Abstract:: Stable isotope analysis of human tissue can provide information about diet independent of artifactual remains. Food is broken down and used in the synthesis of body tissue, so the isotopic composition of hair keratin reflects the isotopic composition of foods consumed. Therefore, the analysis of hair can provide a window...

Knowledge and attitudes about genital herpes and acquired immunodeficiency syndrome among future teachers

Creator:: Mix, Katherine A.
Abstract:: This study measured knowledge and attitudes about genital herpes and human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) in a sample of future teachers from the College of Education at Oregon State University. The objectives of the study were 1) to determine if students possess accurate knowledge about the two diseases; 2)...
