On the abyssal temperatures of the world oceans

Creator:: Olson, Boyd Ellertson
Abstract:: In comparison with solar radiation, the energy of geothermal heat flowing through the sea bottom is extremely small; nevertheless, this energy is not insignificant in the circulation of the bottom water. Calculations indicate that in the deep basins of the South Atlantic the water volume transport necessary to remove this...

Calanoid copepod diet in an upwelling system : phagotrophic protists vs. phytoplankton

Creator:: Fessenden, Lynne M.
Abstract:: Calanoid copepod diet was investigated in Oregon coastal waters to determine the trophic significance of phagotrophic protists as copepod prey within an ecosystem where the microplankton biomass is typically dominated by large diatoms. Prior to and during the 1991 upwelling season, clearance rates on phytoplankton and phagotrophic ciliates were measured...

Ecological interrelationships between summer resident gray whales (Eschrichtius robustus) and their prey, mysid shrimp (Holmesimysis sculpta and Neomysis rayi) along the central Oregon coast

Creator:: Newell, Carrie
Abstract:: The ecological interaction between the largest coastal predator, the gray whale (Eschrichtius robustus) and the most abundant shallow water marcrozooplanktonic prey, mysids, were examined in a poorly-understood predator-prey relationship along the central Oregon coast. From 2002-2008, 83 seasonal gray whales were identified. These whales returned each year around Memorial Day...

Transmission and attenuation of the primary seismic wave, [delta]=100 to 600 KM

Creator:: Long, L. T. (Leland Timothy)
Abstract:: The character of the primary seismic wave in the range of distances between 100 and 600 km is affected by such factors as the nature of the source, exponential attenuation, crustal structure, type of wave propagation, recording site geology and instrument response. The first arrivals from the GNOME and SHOAL...

Bio-physical interactions of small pelagic fish schools and zooplankton prey in the California Current System over multiple scales

Creator:: Kaltenberg, Amanda May
Abstract:: Small pelagic fish represent a critical trophic link between plankton and large predators in marine upwelling ecosystems such as the California Current System. Populations of these fish are highly variable over time and are characterized by extreme fluctuations in abundance, which have significant ecosystem impacts. The causes driving this instability...

Influence of upwelling-season coastal currents on near-bottom dissolved oxygen concentrations over a submarine bank

Creator:: Adams, Katherine A.
Abstract:: Wind-driven coastal upwelling brings subsurface water onto the central-Oregon shelf after the spring transition each year. This cold and salty source water is oxygen-poor, yet above the hypoxic threshold, dissolved oxygen < 1.4 ml l⁻¹. Once on the shelf, dissolved oxygen (DO) concentrations of upwelled near-bottom waters are modified by...

Bathymetry and structure of San Clemente Island, California, and tectonic implications for the southern California continental borderland

Creator:: Ridlon, James Barr
Abstract:: Five lithologic units, ranging in age from Middle Miocene to Recent, are defined on the basis of continuous seismic reflection profile records. Two of the units are Miocene sedimentary and volcanic rocks that have been truncated to form a major unconformity (post-orogenic surface) related to the most recent major tectonism...

Geology of the continental terrace off the central coast of Oregon

Creator:: Maloney, Neil Joseph
Abstract:: The continental terrace west of Oregon between 43° 50'N and 44° 40' N latitude is 50 to 55 miles wide. It consists of a continental shelf, 16 to 35 miles wide, and a continental slope, 16 to 37 miles wide. The eastern portion of the shelf is a smooth, sediment...
