Ocean Acidification Impacts on Bivalves at Multiple Organizational Levels: From Individual Larvae to Bivalve Aggregations Habitats

Creator:: Gimenez Calvo, Iria
Abstract:: Many marine bivalves are sensitive to ocean acidification (OA) stress and often show heightened sensitivity during brief early larval and post-larval life stages, potentially leading to population bottlenecks. Most of the evidence to date has been collected in laboratory experiments that focused on physiological responses at the organismal level under...

Hydrogen isotopic composition of C₃₇ alkenones and the ecology and physiology of coccolithophores

Creator:: Wolhowe, Matthew D.
Abstract:: A three-part study was conducted into the impact of physiological and ecological variables on the net isotopic fractionation of hydrogen, α[subscript K₃₇], expressed in C₃₇ alkenones. First, alkenone-producer production, abundance, and export were characterized in the summertime Gulf of California and Eastern Tropical North Pacific using compound-specific, labeled in situ...

Physical factors affecting the spatial distribution of infaunal bivalve assemblages and species along the continental shelf of the Pacific Northwest

Creator:: Labou, Stephanie Grace
Abstract:: The spatial distribution and abundance patterns of benthic infauna result from interactions with a host of environmental variables including sediment characteristics (percent silt-clay, grain size, total organic carbon), depth, temperature, and dissolved oxygen. This thesis focuses on the association of bivalve assemblages and species with potentially influential environmental variables along...

Exploring the Magnetic Properties of Specific Grain-Sizes to Understand Marine Depositional Systems: A Case Study from the Eirik Ridge South of Greenland over the Last Glacial Cycle

Creator:: Freiberg, Benjamin T.
Abstract:: Disentangling sediment source from sediment transport is a fundamental marine geologic challenge critical to the interpretation of any sedimentary record. The Eirik Ridge, a sediment drift south of Greenland, receives terrigenous sediment primarily from subglacial erosion of south Greenland’s Precambrian bedrock and Paleogene volcanics that outcrop in east Greenland and...

Seasonality of U[superscript K’]₃₇ temperature estimates as inferred from sediment trap data

Creator:: Rosell-Melé, Antoni and Prahl, Fredrick G.
Abstract:: The seasonality of sea surface temperatures (SST) estimated from the alkenone-U[superscript K’]₃₇ index has been a debated issue since the development of the sediment trap time series data from 34 sampling locations, we show that the maximum alkenone flux in sediment traps varies markedly across the oceans, only on latitude...

Spatio-Temporal Analysis and Modeling in the Marine Environment : Humpback Whale Genetic Variability and Seabird Distributions in the Northeastern Pacific Ocean

Creator:: Dick, Dorothy Marie
Abstract:: The rapid decline of marine ecosystems worldwide and the failure of traditional single species management pushed for the development of ecosystem-based conservation measures such as marine protected areas (MPA) to slow the loss of marine biodiversity. One approach to MPA creation advocates targeting marine megafauna (e.g., marine mammals, seabirds, sharks,...

Precipitation and winter temperature predict long-term range-scale abundance changes in Western North American birds

Creator:: Illán, Javier Gutiérrez, Thomas, Chris D., Jones, Julia A., Wong, Weng-Keen, Shirley, Susan M., and Betts, Matthew G.
Abstract:: Predicting biodiversity responses to climate change remains a difficult challenge, especially in climatically complex regions where precipitation is a limiting factor. Though statistical climatic envelope models are frequently used to project future scenarios for species distributions under climate change, these models are rarely tested using empirical data. We used long-term...

Early to Late Holocene Surface Exposure Ages From Two Marine-Terminating Outlet Glaciers in Northwest Greenland

Creator:: Reusche, Melissa M., Marcott, Shaun A., Ceperley, Elizabeth G., Barth, Aaron M., Brook, Edward J., Mix, Alan C., and Caffee, Marc W.
Abstract:: Terrestrial chronologies from southern Greenland provide a detailed deglacial history of the Greenland Ice Sheet (GIS). The northern GIS margin history, however, is less established. Here we present surface exposure ages from moraines associated with two large outlet glaciers, Petermann and Humboldt, in the northwestern sector of the GIS. These...

Competing Roles of Sea Level Rise and Sediment Supply on Sediment Accretion and Carbon Burial in Tidal Wetlands; Northern Oregon, USA

Creator:: Peck, Erin K.
Abstract:: Quantification of contemporary sediment and carbon accumulation within Oregon tidal saline wetlands will: (1) fill a critical knowledge gap, and (2) naturally test without complicating variables whether sea level rise or sediment supply primarily control wetland growth. Here we measure vertical accretion rates and carbon burial rates in three Oregon...
