Spectral particulate attenuation and particle size distribution in the bottom boundary layer of a continental shelf

Creator:: Boss, Emmanuel, Pegau, W. Scott, Gardner, Wilford D., Zaneveld, J. Ronald, Barnard, Andrew H., Twardowski, Michael S., Chang, G. C., and Dickey, T. D.
Abstract:: Spectral attenuation and absorption coefficients of particulate matter and collocated hydrographic measurements were obtained in the Mid-Atlantic Bight during the fall of 1996 and the spring of 1997 as part of the Coastal Mixing and Optics experiment. Within the bottom boundary layer (BBL) the magnitude of the beam attenuation decreased...

Phenology of particle size distributions and primary productivity in the North Pacific subtropical gyre (Station ALOHA)

Creator:: White, Angelicque E., Letelier, Ricardo M., Whitmire, Amanda L., Barone, Benedetto, Bidigare, Robert R., Church, Matthew J., and Karl, David M.
Abstract:: The particle size distribution (PSD) is a critical aspect of the oceanic ecosystem. Local variability in the PSD can be indicative of shifts in microbial community structure and reveal patterns in cell growth and loss. The PSD also plays a central role in particle export by influencing settling speed. Satellite-based...

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...

Variability in satellite winds over the Benguela upwelling system during 1999–2000

Creator:: Risien, Craig M., Reason, C. J. C., Shillington, F. A., and Chelton, Dudley B.
Abstract:: Wind stress variability over the Benguela upwelling system is considered using 16 months (01 August 1999 to 29 November 2000) of satellite-derived QuikSCAT wind data. Variability is investigated using a type of artificial neural network, the self-organizing map (SOM), and a wavelet analysis. The SOM and wavelet analysis are applied...

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....

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...

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,...

Spatial and temporal variability of absorption by dissolved material at a continental shelf

Creator:: Boss, Emmanuel, Pegau, W. Scott, Zaneveld, J. Ronald, and Barnard, Andrew H.
Abstract:: Optical properties of dissolved (colored dissolved organic material (CDOM)) and particulate matter and hydrographic measurements were obtained at the Mid-Atlantic Bight during the fall of 1996 and the spring of 1997 as part of the Coastal Mixing and Optics experiment. To assess the temporal and spatial variability, time series were...

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...

Extracting the internal tide from data: Methods and observations from the Mixed Layer Dynamics Experiment

Creator:: Levine, Murray D. and Richman, James G.
Abstract:: Several methods are developed for analyzing data containing a highly variable internal tide. In particular, the methods are aimed at the analysis of moored observations with relatively few measurements in the vertical. The analysis depends upon an "elliptical decomposition" that is a generalization of the familiar "rotary decomposition." The technique...
