Plague in London : a case study of the biological and social pressures exerted by 300 years of yersinia pestis

Creator:: Hall, Alice
Abstract:: The Second Pandemic had a profound impact on the people of Europe. In the few years between 1347 and 1350, a new epidemic disease spread across the entirety of Europe and killed between one third and two thirds of the population. While this initial wave was important, the real significance...

Sediment transport on the northern Oregon continental shelf

Creator:: Harlett, John Charles
Abstract:: The distribution of surface sediments on the northern Oregon continental shell is characterized by a nearshore sandy facies and an outer shelf muddy facies, separated by a mid-shelf zone of mixed sand and mud. Currents which have been measured at 130 centimeters above the bottom indicate that the distribution of...

Siberian-Arctic shelf surface-sediments: sources, transport pathways and processes, and diagenetic alteration

Creator:: Viscosi-Shirley, Carolyn
Abstract:: This thesis investigates lithogenic sediments on the Siberian Arctic shelf, their sources, modes of dispersal, transport pathways and post-depositional diagenetic alteration. Working with cores collected from the Chukchi, East Siberian and Laptev Seas, we characterize surface-sediment elemental chemistry and clay mineralogy. We identify five regions with endmember sedimentary compositions. Comparing...

Regional population dynamics of Argyrotaenia citrana in Northwest caneberry : phenology, overwintering survivorship, and movement as measured by pheromone traps and larval sampling

Creator:: Knight, Alan Lee
Abstract:: Developmental requirements were determined for both larva and pupa as 503 and 176 degree-days (dd) above a lower threshold of 5°C. Adult emergence occurred from 300 to 700 dd accumulated from January 1st. Cumulative male emergence preceded female's by 50 - 80 dd. A PETE phenology model modified to include...

Oregon's Water Temperature Standard and its Application: Causes, Consequences, and Controversies Associated with Stream Temperature

Creator:: Independent Multidisciplinary Science Team (Or.)
Abstract:: Oregon water temperature standards were described by former Oregon Governor John Kitzhaber’s Office as “an important component of the water quality element of the Oregon Plan [for Salmon and Watersheds]”. In 1998, Governor Kitzhaber’s Office and the Oregon Legislature asked the Independent Multidisciplinary Science Team (IMST) to examine and review...

Establishment and dynamics of methane-oxidizing microbial communities in marine sediments

Creator:: Klasek, Scott A.
Abstract:: Marine sediments are vast sources and reservoirs of methane, a potent greenhouse gas. Most of this methane is anaerobically oxidized by archaea before it can reach the overlying ocean, though the efficiency of this process often depends on methane fluxes and mechanisms of fluid transport. Anaerobic methanotrophic archaea, or ANME,...

Flood history and sedimentation at the mouth of Redwood Creek, Humboldt County, California

Creator:: Ricks, Cynthia L.
Abstract:: Since the early 1950's, the distribution of sediment at the mouth of Redwood Creek has been altered by the effects of channel aggradation and channelization along the lower reach. Severe flooding in 1953, 1955, and 1964 caused bank erosion, landsliding, and channel geometry changes along Redwood Creek. The increased sediment...

Foraminiferal faunal estimates of paleotemperature: Circumventing the no-analog problem yields cool ice age tropics

Creator:: Mix, Alan C., Morey, Ann E., Pisias, Nicklas G., and Hostetler, Steven W.
Abstract:: The sensitivity of the tropics to climate change, particularly the amplitude of glacial‐to‐interglacial changes in sea surface temperature (SST), is one of the great controversies in paleoclimatology. Here we reassess faunal estimates of ice age SSTs, focusing on the problem of no‐analog planktonic foraminiferal assemblages in the equatorial oceans that...

Geochemical Fingerprinting of Metals from Non-Ferrous Smelting Emissions within Lake Sediments

Creator:: Rutila, Elizabeth C.
Abstract:: The research presented in this thesis seeks to further our understanding of the geochemical signatures that can be used to trace and quantify non-ferrous smelting emission inputs into the environment. Strong evidence suggests that emissions from the non-ferrous smelter in Trail, BC are the primary source of metals deposited from...

Ocean Temperature Variability during the Late Pleistocene

Creator:: Hoffman, Jeremy Scott
Abstract:: This dissertation explores one overarching question relevant to the paleoclimate of the latest Pleistocene glacial cycle (approximately the last 130,000 years): “How did spatial and temporal evolution of ocean temperature, both at the surface and interior, relate to other parts of the climate system in the late Pleistocene?” Results from...
