Marine geology of the continental margin off southern Oregon

Creator:: Spigai, Joseph John
Abstract:: The continental margin off southern Oregon, which includes the shelf and slope from Cape Blanco to the Oregon-California border, exhibits a distinctive marginal-plateau structural pattern which divides the margin into the continental shelf, the upper continental slope and its associated benches, and the lower continental slope. Lutum transport and deposition...

Computer analysis of the surface current field off Oregon based on drift bottle data

Creator:: Lung, Hu Ernest
Abstract:: The fall-winter surface current field off Oregon was determined by analysis of ten years of drift bottle data. Computer programs were developed for generating bottle tracks on a numerical grid, for interpolating bottle velocity components to fill void grid points and for smoothing irregularities in the velocity fields. Charts are...

Distribution of Euphausiacea and Copepoda off Oregon in relation to oceanographic conditions

Creator:: Hebard, James Frank
Abstract:: Fifty-two one-meter plankton net samples from four stations off Newport, Oregon, were examined for composition and abundance of euphausiids and copepods. They provided data on dominance, species associations and environmental relationships. The euphausiid-copepod population off Oregon is composed of 12 numerically dominant species. These species occurred in most of the...

Plankton and nutrient ecology of the Columbia River estuary

Creator:: Haertel, Lois Steben
Abstract:: Monthly samples of nutrients, phytoplankton and zooplankton were taken in the Columbia River estuary over a period of 16 months in order to determine distribution with season and salinity, and interrelationships between plankton and nutrients. Nitrate and phosphate levels in the river water entering the estuary are high in the...

The distribution of hyperiid amphipods off the Oregon coast

Creator:: Van Arsdale, Harriet Ann
Abstract:: Hyperiid amphipods from one-meter plankton net collections made over a two year period at stations 15, 25, 50, and 65 nautical miles off Newport, Oregon, were examined. Nineteen species were identified. The occurrence of some species off Oregon significantly extended the known geographic ranges. To my knowledge Scina crassicornis burmudensis...

Magnetic and gravity interpretation of Yaloc-69 data from the Cocos plate area

Creator:: Lu, Richard Shih-Ming
Abstract:: Magnetic, gravity and bathymetry data were collected on an extended cruise of the R/V Yaquina in 1969. The last set of data was obtained from those track lines leaving the Panama Basin. The area covered is mainly the Cocos plate (Molnar and Sykes, 1969). The data is analyzed and compared...

Coastal landslides in northern Oregon

Creator:: North, William Benjamin
Abstract:: Landsliding is a significant contributor to continuous erosion of the 150-mile northern Oregon coast. Direct loss of land to the sea by landslides occurs along 47 percent of the coast. The remaining 53 percent has minor shifting of sand along depositional areas such as spits and dunes. These minor movements...

Antarctic intermediate water in the South Pacific Ocean

Creator:: Johnson, Ron (Ronald E.)
Abstract:: The distribution of Antarctic Intermediate Water in the South Pacific has been examined using a model of horizontal advection, along the Sigma-t surface 27.10, with three point vertical mixing. The core of the Antarctic Intermediate Water mass was traced from the Antarctic Convergence northward. The charts used to describe the...
