Phytoplankton of an ice-edge bloom in the Ross Sea, with special reference to the elemental composition of Antarctic diatoms

Creator:: Carbonell, Maria Consuelo
Abstract:: A phytoplankton bloom dominated by the pennate diatom Nitzschia curta (Van Heurck) Hasle was observed during January-February 1983 at a receding ice-edge in the Western Ross Sea, Antarctica. The core of the bloom was found between 100-150 Km from the ice-edge. Nitzschia curta cell densities up to 22 x 10⁶...

Submarine plateau volcanism and Cretaceous Ocean Anoxic Event 1a : geochemical evidence from Aptian sedimentary sections

Creator:: Walczak, Paul S.
Abstract:: Marine sediments exceptionally rich in organic carbon, known as black shales, occur globally but intermittently in well correlated Cretaceous successions. The presence of black shales indicates that sporadic, ocean-wide interruption of normal respiration of marine organic matter during oxygen-deficient conditions has occurred. Submarine volcanism on a massive scale, related to...

An analytical method for the determination of molecular hydrogen in seawater

Creator:: Borgerson, Mark John
Abstract:: I have developed an analytical method for the determination of molecular hydrogen in seawater. It is based on the change of hydrogen concentration in a 30 cc. volume of air as it is equilibrated with a one-liter sample of seawater. The change in hydrogen concentration in the air is measured...

Reproduction and growth of the Pacific basket-cockle, Clinocardium nuttallii Conrad, from intertidal and subtidal environments of Netarts Bay

Creator:: Ratti, Frank Douglas
Abstract:: Age structure and growth of shells of the Pacific basket-cockle, Clinocardium nuttallii in Netarts Bay, Oregon, were investigated with special emphasis on the differences between subtidal and intertidal populations. The cockle was chosen for study because its growth is highly sensitive to physical factors in the environment. Evidence is presented...

Bioenergetics and behavior of the krill Euphausia pacifica in the California Current System off the Oregon coast

Creator:: Lindsey, Brie J.
Abstract:: Euphausia pacifica, the North Pacific krill, is a key grazer in the California Current System and an important prey item for consumers such as salmon, seabirds, and whales. As a crucial link between phytoplankton and higher trophic levels, it is essential to understand both the behavior and bioenergetics of this...

Feeding habits of northern fur seals (Callorhinus ursinus) in the eastern Bering Sea

Creator:: Sinclair, Elizabeth
Abstract:: This study was conducted to determine the composition and size of prey consumed by northern fur seals (Callorhinus ursinus) in the eastern Bering Sea. Eighty three northern fur seals were collected in the summer and fall of 1981, 1982, and 1985 for examination of gastrointestinal contents. A total of 139...

Rainfall over coastal waters of the Pacific Northwest

Creator:: Reed, Ronald Keith
Abstract:: The objective of this study was to ascertain the magnitude and distribution of rainfall over coastal waters of the northwestern United States and to compare values with those at nearby land stations. Precipitation was measured with gauges at Totem, rainfall amounts were assessed from weather reports at lightships off the...

Size classes, population structure, growth, sex ratio, and size and age at maturity of Chionoecetes tanneri Rathbun (Brachyura:Majidae) off the Oregon coast

Creator:: Tester, Patricia A.
Abstract:: During eleven cruises conducted off the Oregon continental slope from April 1973 to March 1975, approximately 1600 specimens of the majid crab Chionoecetes tanneri Rathbun were collected. A time sequence of size frequency histograms and bivariate plots of allometric measurements were used to determine size classes, population structure, growth and...

Ecological aspects of two wood-boring molluscs from the continental terrace off Oregon

Creator:: Tipper, R. C.
Abstract:: A mooring system was designed and constructed to make possible the installation and the recovery of racks of sample panels for a study of deep-ocean wood-boring molluscs. Racks containing pine, fir, oak, and cedar boards were exposed to borer attack at six stations with depths of 50, 100, 150, 200,...
