Coastal sand dunes and beaches offer a variety of ecosystem services such as coastal protection, sand stabilization, species conservation, and recreation. However, the management and balance of ecosystem services offered by dunes and beaches is challenging when ecosystem services interact across the landscape. Management focusing only on one ecosystem service...
Coastal flood hazard zones and the design of coastal defenses are often devised using either the maximum recorded total water level (TWL) or a 'design' event such as the 100-year return-level flood, usually projected from observed extreme events. Despite technological advances driving more consistent instrumental records of wave heights and...
This report presents observations from two programs in 1975, WISP and UP-75 to study circulation off Oregon. WISP was a study of the transition between the winter and spring regimes, and UP-75 was designed to determine whether there is a poleward undercurrent along the continental slope during the upwellinq season....

depth of 30...
The study of the vegetation of one of the natural coastal
prairies in Oregon was undertaken for the purpose of describing
some of its synecological features. Specific objectives of the study
were to describe certain plant assemblages in the study area, present
phenological relationships on some of the assemblages, and...
Although plant remains, such as opal phytolith and charcoal analyses, have been used since the beginning of the 20th century to reconstruct past environments by ecologists and botanists, only recently have these techniques been considered by archaeologists in understanding the past at the site level. This study employs opal phytolith...
Knowledge of the pelagic organisms in vast areas of the open ocean is very limited. This is particularly true of the small nekton or swimming forms such as fishes, squid, prawns and euphausiids, which are important as intermediate animals in the food chain and are preyed upon by species such...
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...
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...
Rockfish (family Scorpanidae) are an important segment of Oregon trawl landings. Two distinct fisheries commonly produce nineteen species with 5 others rarely seen. A description of catch and catch per unit effort in the Pacific ocean perch and "other rockfish" fisheries is provided. Also reported are species composition of sampled...
This report summarizes information obtained from groundfish surveys conducted by the Oregon Department of Fish and Wildlife from 1971 through 1974. The program was a comprehensive marine resource survey of the continental shelf and upper continental slope off Oregon between the Columbia River and Cape Blanco. Major goals were: (1)...
Oregon Fishermen in Ocean Observing Research (OrFIOOR) is a cooperative research program between ocean scientists and fishermen in the Pacific Northwest. Dungeness crab fishermen attach sensor packages (temperature and dissolved oxygen) to crab pots. The pots serve as platforms of opportunity for ocean observing. This study examines three principle questions...

THOMPSON, and R/V YAQUINA. This report contains the observations made on four YAQUINA cruises between June and August 1973 (Table I). Observations were...
Aanderaa recording current meters, moored off the Oregon coast at fixed depths measured water temperature, current speed, current direction and for some meters, conductivity and pressure. In addition to these subsurface meters, surface meteorological buoys were installed to measure wind speed, wind direction, air and water temperature. Data from each...
Aanderaa recording current meters, moored in CUE-I off the Oregon coast at specific depths along both the Newport hydrographic line and perpendicular to the isobaths off Depoe Bay, were set to measure water temperature, current speed, current direction and, in some cases, pressure. In addition, surface buoy meteorological stations were...

A geoarchaeological investigation was conducted at the Devils Kitchen archaeological site, located in the Devils Kitchen State Park along the southern Oregon coast. In this thesis research, the author paired previous and recent excavated stratigraphy profiles to define culturally significant deposits. These stratigraphic units were defined further geochemically using a...
Freshwater provided from river discharge influences the dynamics and circulation of most continental shelves around the world. It has profound effects on the transport and fate of materials and substances originated from rivers and estuaries, as well as on the ocean biogeochemistry and marine ecosystems. The effect of buoyancy forcing...

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...
This compilation is meant only to be a guide because it is imperfect. I gathered these citations during a single search of the sources cited in section B; ideally, I would have gone through all those sources again to perhaps find records that I missed or to correct errors that...
During the W7711A cruise, from November 5 through November
13, 1977, a series of measurements were made on the hydrography, suspended particulate matter (spm), nutrients, first and second trophic level biomasses, primary productivity and zooplankton species for the purpose of gaining concurrent winter time information on these parameters. The cruise...
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...
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...
This is the first of two technical reports derived from the dissertation

report we give the theoretical development of the rotary component
approach to the bispectrum and cross-bispectrum among...
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...
First-order analyses of wind and current time series obtained from a Totem buoy off the Oregon coast during 1970 are presented. In addition, winds at Totem are compared with winds recorded simultaneously at Newport, Oregon.
In September 1988, the U.S. Secretary of the Interior and the Governor of Oregon announced the creation of the joint state-federal Placer Minerals Technical Task Force. The group was charged with performing an analysis of the potential economic and environmental aspects of placer mineral mining in the nearshore waters of...
