Sedimentary organic matter : distribution and alteration processes in the coastal upwelling region off Peru

Creator:: Reimers, Clare E.
Abstract:: Recent organic-rich deposits on the Peru continental margin occur along the upper slope (100-450 m) between about ll°S and 16°S and along the lower continental slope (>2000 m). The upper slope deposits reflect high biological production in response to coastal upwelling, but preservation of organic matter is enhanced by the...

Macroscale to local scale variation in rocky intertidal community structure and dynamics in relation to coastal upwelling

Creator:: Freidenburg, Tess L.
Abstract:: Understanding how large-scale processes (>100 kms) influence ecological communities is currently a major focus in ecology. In marine systems, coastal upwelling, a large-scale oceanographic process in which surface water pushed offshore by winds is replaced by cold, nutrient-rich water from depth, appears to cause variation in rocky intertidal communities. Along...

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...

Ecological subsidies to rocky shore communities : setting the stage for community dynamics in the Northeast Pacific

Creator:: Krenz, Christopher
Abstract:: This dissertation focuses on the importance of pelagic subsidies in the Northeast Pacific to rocky shore community regulation. My results document the patterns of pelagic subsidy supply, determine if those subsidies are correlated with community structure, and examine if community regulation differs between areas of high- and low-subsidies. Understanding how...

Organization of persistent upwelling structures : hydrographic observations, 5 April-10 May 1983. Vol. 2

Creator:: Chelton, Dudley B., Paluszkiewicz, Theresa, Chandler, William, and Atkinson, Larry P.
Abstract:: The area near Point Arguello has long been recognized as a location of strong upwelling. A tongue of biologically active waters was observed in the earliest studies of this region (Sverdrup and Allen, 1939). More recently, satellite estimates of chlorophyll by the Coastal Zone Color Scanner (CZCS) on Nimbus-7 have...

The role of oxygen and other environmental variables on survivorship, abundance, and community structure of invertebrate meroplankton of Oregon nearshore coastal waters

Creator:: Eerkes-Medrano, Dafne I.
Abstract:: The high productivity of Eastern Boundary Upwelling Ecosystems (EBUE), some of the most productive ecosystems in the globe, is attributed to the nutrient rich waters brought up through upwelling. Climate change scenarios for coastal upwelling systems, predict an intensification of coastal upwelling winds. Associated with intensification in upwelling are biogeochemical...

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...

Numerical model investigations of wind-driven coastal circulation

Creator:: Cervantes, Brandy T.
Abstract:: The effects of wind forcing on coastal ocean circulation are studied using a numerical modeling approach. The first region of interest is on the North Carolina shelf, where the Coastal Ocean Processes (CoOP) Inner Shelf Study (ISS) took place during August - November 1994. ISS observations are used to initialize,...
