Propagation and forcing of high frequency sea level variability in the eastern equatorial Pacific

Creator:: Cornejo-Rodriguez, M. Pilar
Abstract:: Sea level and wind data from coastal and island stations from Buenaventura, Colombia (4°N) to Callao, Peru (12°S) have been analyzed for the 1979-1984 time period, to describe the seasonal and interannual variations in the characteristics of short time scale variability (1-2 weeks). Auto- and cross spectral analyses are used...

Studies on the spatial variability of phytoplankton physiology and biomass in the Oregon upwelling system

Creator:: Sanders, Rachel B.
Abstract:: The Oregon upwelling system is a region of high biomass and primary productivity as well as strong mesoscale variability. In order to examine the interaction of physical forcing and ecosystem dynamics, four 3-week sampling cruises were conducted in the Oregon upwelling system as part of the Northeast Pacific Global Ocean...

Surfgrasses (Phyllospadix spp.) as dynamic foundation species for macroinvertebrates along the Oregon coast

Creator:: Moulton, Orissa M.
Abstract:: Foundation species are important components of ecosystems because they provide habitat and ameliorate stressful conditions for residents. This thesis considers the role of surfgrasses (Phyllospadix spp.) as dynamic foundation species on the coast of Oregon in two studies. Chapter 2, which presents an observational survey of two Phyllospadix congeners, investigates...

Comparing the hydrography and copepod community structure of the continental shelf ecosystems of Washington and Oregon, USA from 1998 to 2009 : can a single transect serve as an index of ocean conditions over a broader area?

Creator:: Lamb, Jesse F.
Abstract:: Bi-weekly sampling of zooplankton and environmental parameters was conducted along a cross-shelf transect off the coast of Newport, OR, USA (44.65°N) from 1996 to present. Results have demonstrated the feasibility of using copepod community structure as an early indicator of ecosystem response to seasonal and large scale environmental changes in...

Interannual and interdecadal variability in the timing and strength of the spring transitions along the United States west coast

Creator:: Bilbao, Pablo A.
Abstract:: Past studies of the Oregon and Washington coast have shown a rapid change in the coastal ocean conditions with the onset of upwelling in spring. This process, called the spring transition marks the change from winter to summer conditions along the west coast of Unites States. To examine the interannual...

Development of satellite bloom detection products for coastal Oregon

Creator:: McKibben, S. Morgaine
Abstract:: Two bloom-detection products were developed for the Oregon coast that describe the relative percent change observed between successive pairs of 8-day chlorophyll-a (CHL) and fluorescence line-height (FLH) products obtained from the MODerate Resolution Imaging Spectroradiometer aboard the Aqua spacecraft (MODIS-Aqua). The CHL[subscript dev] and FLH[subscript dev] products, respectively, were optimized...

A cooperative effort to track Humboldt squid invasions in Oregon

Creator:: Chesney, Tanya A.
Abstract:: Interannual variability of Humboldt squid (Dosidicus gigas) occurrence in the northern California Current System is largely unknown. In Oregon, the distribution of this versatile predator and what is influencing their range expansion from Mexico is poorly understood due to the recent nature of their "invasion" and a lack of monitoring....

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...

The Costa Rica Dome : a study of physics, zooplankton and blue whales

Creator:: Matteson, Robyn S.
Abstract:: At the Costa Rica Dome (CRD), upwelling associated with cyclonic circulation and the presence of a shallow thermocline support a highly productive biological habitat, exploited by marine fauna at several trophic levels. During January 2008, a cruise to the CRD by the R/V Pacific Storm was conducted to relocate blue...
