On the noncorrelation of the vertical structure of light scattering and chlorophyll α in case I waters

Creator:: Kitchen, James C. and Zaneveld, J. Ronald
Abstract:: The relationships between beam attenuation, absorption, suspended particle concentration, size distribution and pigment content are examined for a region where the particle concentration and pigment maxima are widely separated. Mie scattering analyses are performed on this data to predict the profiles of backscattering. It was found that absorption and scattering...

Poleward propagating subinertial alongshore surface currents off the U.S. West Coast

Creator:: Kim, Sung Yong, Cornuelle, Bruce D., Terrill, Eric J., Jones, Burt, Washburn, Libe, Moline, Mark A., Paduan, Jeffrey D., Garfield, Newell, Largier, John L., Crawford, Greg, and Kosro, P. Michael
Abstract:: The network comprising 61 high-frequency radar systems along the U.S. West Coast (USWC) provides a unique, high resolution, and broad scale view of ocean surface circulation. Subinertial alongshore surface currents show poleward propagating signals with phase speeds of O(10) and O(100–300) km d⁻¹ that are consistent with historical in situ...

Intersite comparison of interannual nearshore bar behavior

Creator:: Ruessink, B. G., Wijnberg, K. M., Holman, R. A., Kuriyama, Y., and van Enckevort, I. M. J.
Abstract:: Long-term (>years) bathymetric data sets collected in six multiple near-shore sandbar systems were analyzed with complex empirical orthogonal function analysis to quantify intersite differences and similarities in cyclic offshore progressive bar behavior. The observations came from a 37-year annually sampled data set of four regions along the Dutch coast (spanning...

Photosynthetic Characteristics and Estimated Growth Rates Indicate Grazing Is the Proximate Control of Primary Production in the Equatorial Pacific

Creator:: Cullen, John J., Lewis, Marlon R., Davis, Curtiss O., and Barber, Richard T.
Abstract:: Macronutrients persist in the surface layer of the equatorial Pacific Ocean because the production of phytoplankton is limited; the nature of this limitation has yet to be resolved. Measurements of photosynthesis as a function of irradiance (P-I) provide information on the control of primary productivity, a question of great biogeochemical...

Observations of Phytoplankton and Nutrients from a Lagrangian Drifter off Northern California

Creator:: Abbott, Mark R., Brink, Kenneth H., Booth, D. R., Blasco, Dolors, Codispoti, L. A., Niiler, Pearn P., and Ramp, Steven R.
Abstract:: A Lagrangian drifter was deployed in a cold filament off northern California as part of the Coastal Transition Zone program. The drifter was equipped with an optical package (consisting of a spectroradiometer, a fluorometer, and a beam transmissometer) suspended at 8.5-m depth and a water sampler suspended at 16.3-m depth....

Scales of variability of bio-optical properties as observed from near-surface drifters

Creator:: Abbott, Mark R., Brink, Kenneth H., Booth, C. R., Blasco, Dolors, Swenson, Mark S., Davis, Curtiss O., and Codispoti, L. A.
Abstract:: A drifter equipped with bio-optical sensors and an automated water sampler was deployed in the California Current as part of the coastal transition zone program to study the biological, chemical, and physical dynamics of the meandering filaments. During deployments in 1987 and 1988, measurements were made of fluorescence, downwelling irradiance,...

Error in predicting hydrosol backscattering from remotely sensed reflectance

Creator:: Weidemann, A. D., Stavn, R. H., Zaneveld, J. Ronald, and Wilcox, M. R.
Abstract:: Monte Carlo simulations are carried out to determine the error in the inversion of backscattering from remotely sensed reflectance when geometrical shape factors of the light field are assumed to be unity. The results show that error in backscattering inversion can vary from a 40% overestimation to a 20% underestimation...

The Batchelor spectrum and dissipation in the upper ocean

Creator:: Dillon, Thomas M. and Caldwell, Douglas R.
Abstract:: Observations of vertical temperature microstructure at ocean station P during the mixed layer experiment (Mile) indicate that the shape of the high-frequency temperature gradient spectrum depends on the relative strengths of turbulence and stratification. For low Cox number ((dT/dz)²)/ (dT/dz)²• the linear range of the Batchelor spectrum is not well...

Time Evolution of Surface Chlorophyll Patterns From Cross-Spectrum Analysis of Satellite Color Images

Creator:: Denman, Kenneth L. and Abbott, Mark R.
Abstract:: Sequences of coastal zone color scanner (CZCS) images from the offshore region adjacent to Vancouver Island, Canada, have been analyzed to estimate the time rate of decorrelation of surface phytoplankton chlorophyll pigment patterns. In these high-latitude, high-pigment areas, CZCS-derived pigment estimates were lower than those obtained from ship samples by...

Application of the implicit particle filter to a model of nearshore circulation

Creator:: Miller, R. N. and Ehret, L. L.
Abstract:: The implicit particle filter is applied to a stochastically forced shallow water model of nearshore flow, and found to produce reliable state estimates with tens of particles. The state vector of this model consists of a height anomaly and two horizontal velocity components at each point on a 128 x...
