The erosion events led to the development of a unique partnership bridging scientists, stakeholders, and various planning agencies. To address these erosion issues, a regional demonstration project for littoral cell hazard planning was undertaken. To support the planning efforts a GIS inventory was created to spatially examine erosion hotspots and aid stakeholders in planning for future chronic and catastrophic erosion events. The GIS combines a physical, cultural, and hazards inventory, a shoreline change analysis, and coastal hazard risk assessment into a decision support tool to facilitate coastal hazards management. Shoreline change analysis examined historical aerial photos and new LIDAR remote sensing technologies, with results showing multiple scale patterns of erosion and accretion that have significant implications to both science and management. Hazard risk zones were generated using predictive erosion models and geological observations. The GIS and decision support system facilitates the examination of hazards to develop avoidance strategies. Through spatial queries, decision-makers can examine various data layers to guide future oceanfront development and redevelopment. The development of this GIS in conjunction with a stakeholder process facilitates community involvement from GIS design through implementation of identified hazard management recommendations. Implementing mechanisms will occur through adoption of local land use policies and changes to park master plans. The interdisciplinary nature of this project allows for the range of stakeholder opinions, thus creating a unique opportunity to address coastal hazards at a regional scale, the same scale at which coastal erosion processes operate.}, keywords = {coastal hazards, coastal processes, erosion, geographic information system, theses}, url = {https://ir.library.oregonstate.edu/concern/graduate_projects/tt44pr85r}, author = {Revell, David L.} } @mastersthesis {14116, title = {Late Holocene Paleoseismicity along the Northern Oregon Coast}, year = {1991}, note = {Maps, drawings of core samples.

Vegetation, soil and hydrological attributes were measured periodically from May, 1978 to March, 1979 along three transects extending parallel to the elevation gradient. Each transect began at point bayward of the lower limit of marsh vegetation and continued to a point shoreward of the perceived upper limit of the marsh on the narrow, stabilized dune ridge separating Netarts Spit from the ocean. Plant species distribution and abundance by cover class was recorded in microplots located at increments of five meters or less along each transect. Soil and hydrological observations at intervals of approximately six weeks were made at 29 primary sampling sites located at increments of 15 meters or less along the transects. Water table fluctuations and soil moisture tension were examined in situ. Soil cores were extracted from the marsh for analysis of interstitial soil moisture content and salinity, soil texture, pH, organic matter content, cation exchange capacity, magnesium, calcium, phosphorus, potassium and sodium content. Data on tidal inundation frequency and duration were provided by the National Ocean Survey from a tide gauge located at Netarts public boat dock. Weather data were obtained from continuously recording hygrothermographs and an accumulating rain gauge located in the ecotone between marsh and upland. Comparative climatic data were obtained from published National Oceanic and Atmospheric Administration Environmental Data Center Bulletins. Analysis of individual environmental gradients was initiated by arranging the data matrix into a composite transect ordered by elevation. Each attribute was then plotted against elevation using graphically comparable scales. Data synthesis was accomplished using a combination of reciprocal averaging ordination (to identify coimlunity gradients) and cluster analysis (for sampling site classification) applied to hierarchical data sets composed of combinations of physical, chemical, and vegetative sampling site attributes. Habitat at lower elevations of the study area (0.70 m below mean high water) is dominated by tidal factors which decrease steadily as one approaches extreme higher high water (0.52 m above mean high water). Fine textured sediments are saturated near the middle elevations of the study area (-0.25 to 1.00 m above mean high water), with the lower and higher elevations dominated by sand. Hydrologic factors (water table depth and soil moisture tension) dominate the highest elevations of the study area but decrease steadily as one approaches mean high water. The remaining environmental factors (interstitial soil moisture content and salinity, cation exchange capacity, specific ion concentrations, organic matter, and pH) may each be interpreted as variants of one or more of the three primary environmental gradients: tides, sediment texture, and hydrology. Interstitial soil moisture salinity, soil moisture tension, and water table depth all show maxima during months with high daily temperatures and low precipitation (Aug.-Sep.,) and minima during months with low daily temperatures and high precipitation (Dec.-Mar.). Interstitial soil moisture content shows the reverse relationship with minima during Aug.-Sep. and maxima during Dec.- Mar. Plant community structure of the tidal marsh may be best understood as a species continuum beginning at about 0.60 m below mean high water characterized by snecies dominance at low elevation (_0.51) to 0.40 m above mean hiah water) givinG way to soecies diversity at higher elevations. This continuum may be locally qraduated into three or more subdivisions or plant communities by the dynamic reltionshi of intertidal deposition and erosion processes. Community structure of the associated dune upland is distinguishable environmentally and floristically as distinct from the tidal marsh at about 0.90 m above mean hich water although no attempt is made to resolve finer details of urland community structure beyond the marsh interface.}, keywords = {ecological succession, estuaries, geographic distribution, marine plants, Netarts Spit, soils, species list, theses, tides, wetland delineation, wetland vegetation}, url = {https://ir.library.oregonstate.edu/concern/graduate_thesis_or_dissertations/kp78gk38n}, author = {Liverman, Marc C.} } @mastersthesis {14606, title = {Abundance, Movements and Feeding Habits of the Harbor Seal, Phoca vitulina, at Netarts Bay, Oregon}, year = {1980}, note = {Analyzed 149 scat samples between August, 1977 and May, 1979.

Evidence is presented which suggests that stresses of the physical environment and biological factors result in oldest individuals being in the subtidal, and that growth of shells is correlated with the amount of tidal submergence. A short-term tagging study was done at two sites and most of yearly growth occurred in the Spring months. Collections were made from July, 1975, through September, 1976, from six sites to study synchronism of gonadal development and fecundity of populations by histological examination of gonads. Synchronism of gonadal development to the ripe stage occurs among intertidal and subtidal populations in the same area, while populations from different areas of the bay do not reach the ripe condition at the same time. There is evidence of protandric spawning behavior, and the hermaphroditic nature of C. nuttallii is compared to that of the Family Tridacnidae.

Utilizing quantitative genetic theory, environmental and genetic components of variance have been compartmented for a variety of quantitative characters of the Pacific oyster, Crassostrea gigas. A significant genetic component of variance in a quantitative attribute related to reproductive fitness implies that selection is being effected upon the system. In the present investigation, the variance of larval survival has been subjected to a genetic evaluation. A statistically significant genetic component of variance has been observed. It is concluded that under the conditions observed, genetic selection is inherent in hatchery operations directed toward the management of this species. The genetic implications of these selective practices are discussed in the text of this thesis. It is suggested that this method for the genetic evaluation of hatchery practices is applicableto other aquatic animals which are propagated in hatcheries. The genetic and environmental components of variance have been estimated for several other economically significant attributes of C. gigas. In every case, a significant genetic component of vanance was observed. Further compartmenting of the genetic variance into additive and non-additive genetic components revealed that a large non-additive component was present in every case observed. This is interpreted as being a consequence of introducing a wild animal into a selective, quasi-domestic culture situation. It is considered likely that after several generations of hatchery culture, selection plateaus will be attained and additive genetic variance will increase relative to other variance components. Based upon these observations, a method for selective breeding of oysters has been proposed. It is suggested that progeny testing is the breeding method best suited for the early stages of selective breeding with oysters and probably for aquaculture in general. Preliminary tests of this method suggest that significant economic gains may be realized through selective breeding of the Pacific oyster.}, keywords = {aquaculture, genetics, Pacific oyster = Crassostrea gigas, shellfish, theses}, url = {https://ir.library.oregonstate.edu/concern/graduate_thesis_or_dissertations/q811kn84d}, author = {Lannan, James E., Jr.} } @mastersthesis {15041, title = {The Japanese Oyster Drill, Ocenebra japonica, in Netarts Bay, Oregon}, year = {1972}, note = {Sometime around 1930-1934, year-old Japanese oysters (Crassostrea gigas) were imported into Netarts Bay, as part of an early commercial growing operation.

Data from spat-baited traps furnished an index of distribution, and indicated the drills may move outward and downward in the summer, returning to the relicts for protection from winter weather when temperatures fall. Snails fed mono-specific diets of C. gigas, cockles (Clinocardium nuttalli), and Olivella biplicata were tested to determine prey preference. Naive (field) and starved specimens were also tested, and statistical comparison of these results demonstrated prey preference could be dietetically altered, and confirmed that C. nuttalli was the chief prey item in the field. A single spring spawning was noted, but few juvenile drills (< 18 mm) were recorded. The presence of numerous small prey- - some of which had been drilled- -and of a population distribution similar to literature reports indicate the population is viable.

Because of their proximity to man and his activities, the maritime sand dunes of Europe, particularly Germany, France, Holland and Scandinavia, have the longest history of stabilization activities and botanical investigation. There are coastal dune areas, some of great extent, in Africa, tropical Asia, Australia, and South America. In general, little published information is available concerning these areas. Ecological studies of coastal dune vegetation and environment have been most extensive in Great Britain, and to a lesser extent, in North America. Of the North American coastal dunes, those of the east coast have received considerable attention while those of the west coast have been largely neglected. Along the Oregon coast are found some of the most extensive and best developed coastal sand dune areas in North America. Occurring on some 225 km. of the state{\textquoteright}s 500 km. of ocean facing coastline, these areas are made up of a great variety of dune landscape features and present unique conditions for the development and maintenance of vegetation. There are many places in this dune area where the strong, constant winds have eroded the sand surface to or near the water table resulting in a stabilized surface - the deflation plain - which provides an excellent starting point for the development of vegetation. After preliminary ground and air reconnaissance, 11 deflation plains were selected for detailed study, ranging in location from Sand Lake on the north to Tahkenitch Creek on the south. These deflation plains and their location are described in detail. Vegetation data (species and cover) were taken on a total of 134 sampling stands, each consisting of five meter-square quadrats for herbaceous vegetation, and one 6 x 6 meter quadrat for shrub and forest vegetation. The species and stand data we arranged on comparative charts so as to bring together stands with mutually occurring species. This resulted in the delineation of seven communities with definite successional relationships. Primary succession begins with one of four herbaceous communities: dry meadow, meadow, rush meadow or marsh. Succession then proceeds to low shrub, tall shrub and finally forest. The dry meadow is dominated by three species: Lupinus littoralis, Ammophila arenaria and Poamacrantha. The site is dry with no standing water at any time. Sand deposition and deflation occur in varying degrees. The important species of the meadow are Festucarubra, Aira praecox, Hypochaeris radicata and Fragaria chiloensis. The surface is dry except for short periods of standing water during the winter months. There is no sand deposition. The rush meadow is characterized by its dense growth of Trifolium willdenovii and Juncus phaeocephalus. The site is low and moist, with water standing on the surface during the winter months. The marsh is found on areas which are quite damp-water stands on the surface for around six months of the year, and is just below the surface for the remainder of the time. It is made up of dense stands of Carex obnupta and Potentilla anserina. The low shrub community is an open stand of Salixhookeriana, Gaultheria shallon, Vaccinium ovatum and Myrica californica. This develops into a tall shrub stage which is frequently an impenetrable thicket with increasing dominance of seedlings of Pinus contorta and Picea sitchensis. Development of a forest of Pinus and Picea is very rapid. If the area is free from disturbance long enough, the shorter lived Pinus dies out, leaving a forest of Picea. The deflation plains represent only part of the many aspects of the total dune landscape still awaiting investigation. The increasing importance of the Oregon coastal dunes to industry and recreation make imperative the initiation of long term ecological studies.}, keywords = {coastal dunes, general ecosystem description, species lists, terrestrial plants, theses}, url = {https://ir.library.oregonstate.edu/concern/graduate_thesis_or_dissertations/08612s992}, author = {Wiedemann, Alfred M.} } @mastersthesis {15201, title = {Distribution of Foraminifera, Netarts Bay, Oregon}, year = {1966}, note = {Found 51 benthic foraminiferal species falling into 4 main groups: the Elphidiella Fauna of the channel, the Elphidium Fauna on the central bay sand flats, the Ammonia Fauna on mud flats and inner bay sand flats, and the Miliammina Fauna characterizing the marsh.}, month = {1966}, pages = {112 p}, school = {Oregon State University}, type = {Doctoral dissertation}, edition = {Ph.

Four major sedimentary environments are recognized including channel, sand flats, mud flats, and marsh. Fine-grained sediment is carried in by streams and deposited in the marshes and mud flats. Fine sand for the channel and sand flats is derived from the open ocean beaches and turbulent zone. Organic carbon varies from 0.1 to 3.5 percent of the sediment and varies inversely with the sediment size. Carbonate carbon is unimportant. Fifty-one benthic foraminiferal species were recognized of which 37 formed two percent of the population in one or more samples. Four foraminiferal faunal groups were recognized: the Elphidiella Fauna inhabiting the channel, the Elphidium Fauna reaching greatest abundance on the central bay sand flats, the Ammonia Fauna inhabiting the mud flats and inner bay sand flats, and the Miliammina Fauna characterizing the marsh. Planktonic foraminiferal populations form less than one percent of the total foraminiferal population. Benthic foraminiferal populations on the order of 80 specimens /cm2 for the live populations and 200/cm3 for the dead are found in the dense vegetation of the marsh. Tidal flat populations are approximately an order of magnitude smaller and the channel population is one to two orders of magnitude smaller than for the tidal flat. Species diversity is greatest on the central bay tidal flats, averaging seven species per sample for live and 15 for dead populations. Values decrease as mud flats, marsh, and channel environments are approached. The total standing crop and most species inhabiting the innermost part of the bay display simultaneous bimodal population maxima in July and January. These peaks are possibly controlled by the availability of food. Ammonia cf. A. beccarii tepida and Elphidium incertum incertum show strong but independent population maxima in July and October respectively. Foraminifera-ostracod ratios range from 0. 6 to 41.5 with a mean of 13.8. Agglutinated-calcareous foraminiferal ratios vary inversely with sediment size and appear to be related to the pH of the sediments.
