Creator:: Dugdale, Richard C., Davis, Curtiss O., and Wilkerson, Frances P.
Abstract:: Remotely sensed sea surface temperature (SST) and a model originally developed for Cap Blanc, northwest Africa [Dugdale et al., 1989], are used to estimate new production (i.e., nitrate uptake, in the sense of Dugdale and Goering [1967]) for the persistent coastal upwelling feature at Point Conception, California. Parameters required to...

Creator:: Sinton, Christopher W., Christie, David M., and Duncan, Robert A.
Abstract:: Lavas from seamounts of the central Galápagos Platform and the Carnegie Ridge increase in age with distance from the western edge of the platform, consistent with a hotspot model for the generation of these features. The areal distribution of seamount ages suggests that the pattern of dispersed volcanism seen on...

Abstract:: Satellite altimeter measurements of marine gravity reveal 100 to 200-km wavelength lineations over a wide area of the Pacific plate oriented roughly in the direction of absolute plate motion. At least three mechanisms have been proposed for their origin: smallscale convective rolls aligned in the direction of absolute plate motion...

Abstract:: Data from an array of bottom pressure gauges and a string of current meters in the vicinity of 47°N, 139°W, are used to examine the deep-ocean variability forced by ocean surface wind stress curl from August 1987 to June 1988. Bottom geostrophic currents are computed from the pressure gauge array,...

Abstract:: The Marquesas archipelago is a short. NW-SE trending cluster of islands and seamounts that formed as a result of volcanic activity over a weak hotspot. This volcanic chain lies at the northern margin of a broad region of warm and compositionally diverse mantle that melts to build several other subparallel...

Creator:: Ramp, Steven R., Garwood, Roland W., Davis, Curtiss O., and Snow, Richard L.
Abstract:: The difference between the temperature of the ocean at 4-cm and 2-m depth was continuously monitored during a cruise to the coastal transition zone off Point Arena, California (38°58′N, 123°45′W), during June 1987. The two temperatures were coincident most of the time but diverged during one nearshore leg of the...

Abstract:: Lake-induced atmospheric circulations over three lakes ranging from 3 to 10 km width are analyzed using data from three aircraft during the 1994 Boreal Ecosystem-Atmosphere Study (BOREAS). A well-defined divergent lake breeze circulation is observed over all three lakes during the day. Under light wind conditions, the lake breeze is...

Abstract:: We use data from a series of small (three to five stations) overlapping magnetovariational (MV) arrays to image variations of vertically integrated electrical conductivity in the crust of southwestern Washington. Two principal structures are revealed: a large north-south trending anomaly (the southern Washington Cascades Conductor (SWCC), which has been detected...

Creator:: Dever, Edward P.
Abstract:: Along- and cross-shelf correlation scales of subtidal cross-shelf (u) and alongshelf (ν) velocities are estimated using moored records from several field programs over the northern California shelf. Over record lengths of 4-6 months, along-shelf correlation scales of ν are greater than maximum mooring separations (60 km). In the cross-shelf direction...

Abstract:: Optimal interpolation (OI) has been used to produce analyses of quasi-geostrophic (QG) stream function over a 59-day period in a 150-km-square domain off northern California. Hydrographic observations acquired over five surveys, each of about 6 days' duration, were assimilated into a QG open boundary ocean model. Since the true forecast...
