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...

Description and analysis of dietary preference of lingcod in the nearshore zone, Oregon

Creator:: Tinus, Craig A.
Abstract:: The lingcod (Ophiodon elongatus) is an important groundfish species in both recreational and commercial fisheries of the Northeastern Pacific. It is a large, fast-growing, generalist predator of invertebrates and fishes. In response to concerns that lingcod may limit populations of rockfishes (Sebastes spp.), I compared the diets of 375 adult...

Patterns of age and growth in young-of-year rockfish, sebastes spp., along the Oregon coast

Creator:: Young, Thomas
Abstract:: Rockfish of the genus Sebastes are important components of Oregon reef communities. I examined patterns of age and growth in young-of-year rockfish across two nested spatial scales – local and regional – along the Oregon coast. Using otolith microstructural examination, I examined the relative importance of local versus regional factors...

Recruitment variability in black rockfish (Sebastes melanops): effects of maternal age on offspring quality

Creator:: Chapman, Colin G.
Abstract:: Black rockfish (Sebastes melanops) is an important marine recreational species throughout the Pacific Northwest. Recent catch data indicate a trend of age-truncation in the black rockfish population off the Oregon coast, with older females rapidly disappearing from the population. In populations with broad age distributions, older fish may contribute disproportionately...

Growth rates and species composition of juvenile rockfish (Sebastes spp.) in Oregon’s nearshore and estuarine habitats

Creator:: Gallagher, M. Brett
Abstract:: Identification of critical habitat for all life stages of commercially exploited fish populations is critical for effective management. Despite a clear need for basic biological information on juvenile rockfish life history, there have been very few efforts to describe distribution and habitat of this life stage, particularly along the Oregon...

Inner-shelf circulation off the central Oregon Coast

Creator:: Kirincich, Anthony R.
Abstract:: Inner-shelf circulation and mechanisms of across-shelf transport of water masses were examined using seven years of observations collected by the Partnership for Interdisciplinary Studies of Coastal Oceans (PISCO) program, a long-term monitoring effort along the central Oregon coast. Since 1998, moored velocity and hydrographic measurements have been obtained during the...

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...

Paleoenvironmental reconstruction of an active margin coast from the Pleistocene to the present : examples from southwestern Oregon

Creator:: Punke, Michele Leigh
Abstract:: This study illustrates geoarchaeological and paleoenvironmental approaches to the investigation of an active margin coastal setting and provides examples of how information gleaned through examination of the stratigraphic record can reveal depositional signatures that provide insights into the geomorphic and tectonic forces active within coastal river basins. Three case studies...

Observations from moorings on the Oregon continental shelf, May-August 2001 : a component of the Coastal Ocean Advances in Shelf Transport (COAST) experiment

Creator:: Boyd, Timothy John, 1958-2013, Levine, Murray D., Kosro, P. Michael, 1951-, Gard, Steve R., Waldorf, Walt, and Oregon State University. College of Oceanic and Atmospheric Sciences
Abstract:: This report documents the oceanographic and meteorological measurements made by the Mooring Observations component of the Coastal Ocean Advances in Shelf Transport (COAST) project during the upwelling experiment from May to August 2001. The focus of COAST is to study the cross-shelf transport processes in a wind-driven system by making...
