  Citation × Citation Citation Abstract Copy Title: The signature of El Nino off Oregon, 1982-1983 Author: Huyer, Andriana, 1945-, Smith, Robert L. (Robert Lloyd), 1935- Current and conductivity, temperature, and depth (CTD) measurements were made over the Oregon shelf near 43°N between February 1981 and April 1984 as part of a large-scale west coast shelf experiment (SuperCODE). The data set includes a nearly continuous record of current velocity and temperature over the continental shelf off Coos Bay from May 1981 through January 1984, CTD sections off Coos Bay in January or February of each year from 1981 to 1984, and CTD sections off Newport (44.6°N) in April 1983, July 1983, and April 1984. The latter are compared with sections off Newport made during the previous two decades. Sea level from the Newport tide gage, daily sea surface temperature at Charleston (43.3°N), the alongshore component of the wind stress at 45°N and the large-scale North Pacific atmospheric pressure pattern provide a climatological perspective. The initial manifestation of El Nino off Oregon was in October 1982: anomalously high sea level, high coastal sea surface temperature, and increased poleward flow. These effects occurred within 1 month of the onset of El Nino off Peru and preceded any local (North Pacific) atmospheric effect by 2-3 months. The anomalous local meteorological conditions, which became manifest in December and January, greatly enhanced the initial effects and inserted their own signal. The first signals of El Nino probably arrived by an oceanic path, but there is no doubt they were subsequently reinforced by anomalous atmospheric conditions.

  Citation × Citation Citation Abstract Copy Title: CTD observations in the coastal transition zone off Northern California from R/V Wecoma, July to August 1988 Author: Oregon State University. College of Oceanography, Fleischbein, Jane Wecoma cruise W8807A was conducted in late July and early August 1988 as part of the Coastal Transition Zone project. CTD observations were made over a standard grid in the coastal transition zone off northern California between 37°N and 39.5°N that was occupied repeatedly during June, July and August; this cruise completed the sixth survey. A total of 88 CTD stations were completed successfully; 68 of these stations were at standard grid positions. Additional sections were added at the southwest corner and the north side of the grid, and along the northern portion of an alongshore line occupied four times in 1987. Maximum sampling depth at most stations was 500 m. Temperature, salinity, light transmission and fluorescence were measured at all stations. This report presents vertical profile plots and tabulations of data at selected depths for each station; vertical sections of temperature, salinity and potential density anomaly (sigma-theta), and maps of temperature, salinity, potential density anomaly, and dynamic topography. Wecoma cruise W8806B (28 June to 24 July 1988) completed 13 transects along the D-line making primarily microstructure and towed thermistor chain observations, but CTD observations were also made. A total of 51 CTD stations were completed. The vertical profile plots and standard depth listings of the CTD data are presented in this report.

  Citation × Citation Citation Abstract Copy Title: On the Effects Of Horizontal Variability of Wind Stress on the Dynamics of the Ocean Mixed Layer Author: de Szoeke, Roland A. The one-dimensional bulk mixed-layer model of Niiler (1975) is extended to two (or three) dimensions to take account of horizontal variation in wind stress on mixed-layer dynamics. Both surface stirring (Kraus and Turner, 1967) and bulk shear (Pollard et al., 1973) entrainment mechanisms are included. The development of horizontal structure in the upper ocean an the subseasonal to seasonal time scale is the focus of interest. An asymptotic two-timing technique is employed to simplify the dynamical equations. Wind-driven advection can be important in establishing and concentrating horizontal gradients of the sea surface temperature. Wind stress curl-driven vertical velocity can be as important as entrainment velocity in determining the horizontal distribution of mixed-layer depth. Several illustrative calculations are discussed. A case with initially horizontally uniform temperature, 0.05°C m⁻¹ initial vertical gradient, and wind stress of 1 dyn cm⁻² and scale of 1000 km, shows horizontal temperature gradients of 0.01°C km⁻¹ in the vicinity of the wind-driven convergence zone after 100 days integration. A similar case, except with initial horizontal gradient of 0.006°C km⁻¹, shows temperature gradients of 0.02°C km⁻¹ after 100 days. In wind-driven convergence zones, mixed-layer depths of 120 m can be achieved after 100 days, by a combination of entrainment and downwelling, mostly the latter, especially after long times. In divergent zones, steady mixed-layer depths can be achieved in less than 100 days through the competition between the effects of upwelling and entrainment. These steady depths range from 20 to 90 m, depending on location. Title: On the Effects Of Horizontal Variability of Wind Stress on the Dynamics of the Ocean Mixed Layer Author: de Szoeke, Roland A.
