The objective of this study was to develop a decision making tool to determine economic feasibility of artisan cheese operations. A survey of current Oregon artisan cheese companies was used to gain knowledge of the fixed and variable costs associated with cheese production and business start-up. The data from this...
Lake Merced results have established the lake as a viable paleoseismic site on the northern San Francisco peninsula. The lake records ~ 2300 years of event beds, 17 in total. Prior to that the lake was open to the ocean and contains marine shells consistent with an estuarine environment. The...
Lack of valid economic data for artisan cheese making is a serious impediment to developing a realistic business plan and obtaining financing. The objective of this study was to determine approximate start-up and operating costs for an artisan cheese company. In addition, values are provided for the required size of...
Holocene turbidites from turbidite channel systems along the active tectonic continental
margins of the Cascadia Subduction Zone (offshore Vancouver Island to Mendocino Triple
Junction) and the northern San Andreas Transform Fault (the Triple Junction to San Francisco
Bay), have been analyzed for sedimentologic features related to their seismic origin. Centimeter...
Turbidite deposition along slope and trench settings is evaluated for the Cascadia and Sumatra-Andaman subduction zones. Source proximity, basin effects, turbidity current flow path, temporal and spatial earthquake rupture, hydrodynamics, and topography all likely play roles in the deposition of the turbidites as evidenced by the vertical structure of the...
Abstract: A series of 23 thin, mostly mud-silt turbidites are found interspersed between larger, well-dated and regionally correlated paleoseismic sandy turbidites that extend along most of the Cascadia margin, northwestern United States. Investigation of the structure, distribution, and sedimentology of these thin mud-silt units supports the interpretation of these units...
Marine and coastal sedimentary archives show that the Cascadia Subduction Zone can generate great earthquakes of ~M9, most recently in 1700 CE, yet we still know little of the impacts of these events inland of the Pacific coast. Inland lakes have recently been exploited for their use as paleoseismic records...
Proceedings of the 82nd Annual Pacific Northwest Insect Management Conference, held January 9-10, 2020 at the Hilton Hotel in Portland, Oregon. These are research reports only, not management recommendations.
Estimating the hydraulic conductivity of earth materials is important for many water resource modeling efforts, including predicting the transport of pollutants in ground water, computing surface runoff for flood control, and computing water budgets. This research implicitly used topography, soil, and climate data to estimate plausible continuous hydraulic conductivity values...
Lower and Middle Devonian strata crop out on the former
stable carbonate platform that existed in the Quinn Canyon Range,
through the carbonate shelf edge in the Pancake Range, to the
carbonate slope and outer-shelf basin in the Reveille Range.
The strata of the Reveille Range record a transition from...
