Food habits, dietary overlap and gastric evacuation rates of rockfishes (genus Sebastes)

Creator:: Brodeur, Richard D.
Abstract:: Euphausiids constituted the major food of five co-occuring species of rockfishes (Sebastes spp.). Copepods, decapods, cephalopods, amphipods, fishes and other pelagic prey were also consumed but were less important to the overall diet. Two species, S. flavidus and S. diploproa, were relatively euryphagous, utilizing a high number of prey taxa....

Long wavelength gravity anomalies and implications concerning a descending lithospheric slab in the Pacific Northwest

Creator:: MacFarlane, William Thomas
Abstract:: The thermal regime of a postulated descending lithospheric slab is calculated. The gravity anomaly associated with such a structure is large in amplitude and long in wavelengh. Observed free-air gravity anomalies in the Pacific Northwest do not indicate a gravitational effect due to a descending slab. Two hypothetical compensation models...

Equatorward jets and poleward undercurrents along the eastern boundary of the mid-latitude north Pacific

Creator:: Pierce, Stephen D.
Abstract:: We sharpen our view of an eastern boundary current region during the upwelling season through the analysis of several data sets. We focus on the mesoscale flow field off of northern California, observed during the Coastal Transition Zone (CTZ) experiment of 1988. First, we estimate tidal currents in the region...

Structure of the Panama Basin from marine gravity data

Creator:: Barday, Robert James
Abstract:: In order to quantitatively examine the crustal structure of the Panama Basin without the benefit of local seismic refraction data, the following assumptions were made: (1) No significant lateral changes in density take place below a depth of 50 km. (2) The densities of the crustal layers are those of...

Crustal structures and tectonism in southeastern Alaska and western British Columbia from seismic refraction, seismic reflection, gravity, magnetic, and microearthquake measurements

Creator:: Johnson, Stephen Hans
Abstract:: Seismic refraction measurements along two unreversed lines indicate that the earth's crust is 26 km thick in southeastern Alaska and 30 km thick along the Inside Passage of British Columbia. The crust in southeastern Alaska, north of Dixon Entrance, consists of a layer 9 km thick with a seismic velocity...

Shear wave attenuation in unconsolidated laboratory sediments

Creator:: Brunson, Burlie A.
Abstract:: Shear wave attenuation measurements were made using ceramic bimorph transducers to excite transverse vibrations in a cylindrical column of unconsolidated sediment. Three different water-saturated sediments were used in an attempt to determine the effects of grain shape and sorting on the frequency dependence of attenuation. The mean grain size of...

Substrate capture, uptake, and utilization of some amino acids by starved cells of a psychrophilic marine vibrio

Creator:: Glick, Melissa Ann
Abstract:: Starved cells of Ant-300, a psychrophilic marine Vibrio, maintained binding and transport systems for glutamic acid, arginine, proline, and leucine. The uptake of these amino acids was inhibited by the uncoupler 2,4-dinitrophenol indicating that an energized membrane was necessary for binding and was maintined in starved cells. The levels of...
