The effect of light intensity on the organic composition of marine phytoplankton diatoms

Creator:: Marmelstein, Allan
Abstract:: Investigation was made into the influence of changing light intensity on the organic and elemental composition of two species of marine diatoms, Ditylum brightwellii and Skeletonema costatum. Analysis was made of the relative changes in soluble and insoluble carbohydrate; polar, non-polar, and total lipid; amino acids; proteins; and total carbon,...

An experimental evaluation of a passive anti-roll tank system

Creator:: Plank, William Sanford
Abstract:: The effectiveness of the passive anti-roll tank system aboard the R/V YAQUINA was determined. Measurements of ship roll, effective waveslope and tank water transfer were analyzed using a systems analysis technique. Time series of the inputs and outputs of the ship/tank system and of the tank itself were processed using...

Tactics of Pacific Northwest albacore fishermen - 1968, 1969, 1970

Creator:: Keene, Donald Frederick
Abstract:: This study examines the relationship between fishing activities of Pacific Northwest albacore fishermen and the availability of albacore. Tactical responses of troll-boat fishermen were compared to changes in daily apparent albacore abundance. Tactical responses included boat aggregation and total applied effort (number of boats) within a particular area, and net...

Geostrophic and Sverdrup transports as indices of flow in the Gulf of Alaska

Creator:: Favorite, F.
Abstract:: The intensification of cyclonic winds in the Gulf of Alaska during winter belies the relatively constant geostrophic circulation as being indicative of actual flow. In the absence of direct current measurements, effects of various meteorological phenomena have been eliminated from monthly mean sea level measurements over the decade 1950 to...

Currents and water masses at the entrance to the Gulf of California, spring 1970

Creator:: Alvarez Sanchez, Luis Gustavo
Abstract:: Hydrographic data and drogue observations were used to describe the circulation and water masses in the upper 500 meters of the region of the entrance to the Gulf of California in the early spring of 1970. The thermohaline structure of the water and the general circulation in the vicinity of...

Late Neogene tectonics of the mouth of the Gulf of California

Creator:: Ness, Gordon Everett
Abstract:: Anomaly timescales for the last 90 million years, derived from marine magnetic profiles and published prior to mid-1979, are summarized, illustrated for comparison, and critically reviewed. A revised timescale is constructed using calibration points which fix the ages of anomalies 2.3', 5.5, 24, and 29. An equation is presented for...
