A terrestrial organic matter depocenter on a high-energy margin adjacent to a low-sediment-yield river : the Umpqua River margin, Oregon

Creator:: Hastings, Roxanne H.
Abstract:: Small, mountainous river systems have been increasingly studied due to their importance as sources of fluvial sediment and organic matter to the coastal ocean. Thus far, studies of small, mountainous river systems have focused on rivers with very high sediment loads. The well-studied Eel River dispersal system in northern California...

High-resolution sampling of particulate organic carbon in a coastal upwelling system

Creator:: Holser, Rachel R.
Abstract:: Summertime, wind-driven upwelling off the Oregon coast delivers nutrient rich water to the surface that fuels the autotrophic production of particulate organic carbon (POC). This POC can be transported horizontally by fluid motions and vertically by sinking to the bottom where it can be entrained in the benthic boundary layer...

Agonistic behavior in three species of Microtus (M. canicaudus, M. oregoni, and M. townsendii)

Creator:: Weil, James Wayne
Abstract:: Agonistic behavior among three species of Microtus live-trapped near Corvallis, Oregon was recorded in order to interpret habitat segregation by the species in areas of syrnpatry. The method used to measure agonistic interaction was similar to that of Colvin (1970). Agonistic behavior was recorded under red light in a neutral...

Novel Copper and Iron Complexes along the Oregon Coastal Upwelling Margin

Creator:: Bright, Peter, W.
Abstract:: Copper and iron are essential micronutrients that are required by marine primary producers for a variety of metabolic processes. Over 99% of both copper and iron are bound within organic complexes in the marine environment, however the molecular identity of many of these complexes remains unknown. The speciation of these...

Patterns of sediment accumulation in the Siletz River Estuary, Oregon

Creator:: Pakenham, Anna
Abstract:: Anecdotal evidence suggests many Pacific Northwest estuaries are filling with sediment due to historical logging activities in upstream watersheds. Using the Siletz River estuary as a case study, this research began by analyzing timber harvest and discharge records of the Siletz River watershed, and found that increased timber harvest coincides...

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...

Site fidelity and colony dynamics of Caspian terns nesting at East Sand Island, Columbia River Estuary, Oregon, USA

Creator:: Collar, Stefanie
Abstract:: Fidelity to breeding sites in colonial birds is an adaptive trait thought to have evolved to enhance reproductive success by reducing search time for breeding habitat, allowing earlier nest initiation, facilitating mate retention, and reducing uncertainty of predator presence and food availability. Studying a seabird that has evolved relatively low...

High-resolution Biological Net Community Production in the Pacific-influenced Arctic: A Multi-method Comparison

Creator:: Cynar, Haley
Abstract:: Patterns of primary productivity in the Arctic are expected to change with continued warming, yet productivity measurements are historically limited, both spatially and temporally. An established method of measuring net biological oxygen production, which can be used to estimate net community production (NCP) rates, is with an equilibrated inlet mass...

Sea-Salt Impacts On Nutrient Cycling In Oregon Coastal Soils

Creator:: Aleman, Ruben
Abstract:: Sea-salt aerosols (SSA) impact the cycling of nutrients within coastal soils, including the mobility of dissolved organic carbon (DOC) and ammonium, denitrification, and litter decomposition. These aerosols are formed during tumultuous weather in the open ocean and are transported and deposited inland by wind. Soils closer to the ocean are...
