The variation in the inherent optical properties of phytoplankton near an absorption peak as determined by various models of cell structure

Creator:: Zaneveld, J. Ronald and Kitchen, James C.
Abstract:: Optical oceanography models of attenuation and scattering properties often contain simple spectral relationships. Electromagnetic theory, however, predicts fluctuations in the spectra of the attenuation coefficients and scattering properties of substances at wavelengths near an absorption peak. We have modeled these effects for phytoplankton using homogeneous, two‐layered, and three‐layered sphere models...

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...

An assessment of phytoplankton primary productivity in the Arctic Ocean from satellite ocean color/in situ chlorophyll-a based models

Creator:: Lee, Younjoo J., Matrai, Patricia A., Friedrichs, Marjorie A. M., Saba, Vincent S., Antoine, David, Ardyna, Mathieu, Asanuma, Ichio, Babin, Marcel, Bélanger, Simon, Benoît‐Gagné, Maxime, Devred, Emmanuel, Fernández‐Méndez, Mar, Gentili, Bernard, Hirawake, Toru, Kang, Sung‐Ho, Kameda, Takahiko, Katlein, Christian, Lee, Sang H., Lee, Zhongping, Mélin, Frédéric, Scardi, Michele, Smyth, Tim J., Tang, Shilin, Turpie, Kevin R., Waters, Kirk J., and Westberry, Toby K.
Abstract:: We investigated 32 net primary productivity (NPP) models by assessing skills to reproduce integrated NPP in the Arctic Ocean. The models were provided with two sources each of surface chlorophyll-a concentration (chlorophyll), photosynthetically available radiation (PAR), sea surface temperature (SST), and mixed-layer depth (MLD). The models were most sensitive to...

Microwave backscattering from surf zone waves

Creator:: Catalán, Patricio A., Haller, Merrick C., and Plant, William J.
Abstract:: The microwave backscatter properties of surf zone waves are analyzed using field observations. By utilizing a preexisting, independent, water surface discrimination technique, the microwave returns were extracted along individual waveforms and the data from shoaling (steepening) waves, surf zone breaking waves, and remnant foam were separated and quantified. In addition,...

Distribution and sources of organic matter in surface marine sediments across the North American Arctic margin

Creator:: Goni, Miguel A., O’Connor, Alison E., Kuzyk, Zou Zou, Yunker, Mark B., Gobeil, Charles, and Macdonald, Robie W.
Abstract:: As part of the International Polar Year research program, we conducted a survey of surface marine sediments from box cores along a section extending from the Bering Sea to Davis Strait via the Canadian Archipelago. We used bulk elemental and isotopic compositions, together with biomarkers and principal components analysis, to...

Particle distributions and dynamics in the euphotic zone of the North Pacific Subtropical Gyre

Creator:: Barone, Benedetto, Bidigare, Robert R., Church, Matthew J., Karl, David M., Letelier, Ricardo M., and White, Angelicque E.
Abstract:: During the summer of 2012, we used laser diffractometry to investigate the temporal and vertical variability of the particle size spectrum (1.25–100 µm in equivalent diameter) in the euphotic zone of the North Pacific Subtropical Gyre. Particles measured with this optical method accounted for ∼40% of the particulate carbon stocks...

Internal wave dissipation under sea ice

Creator:: Morison, James H., Long, Charles E., and Levine, Murray D.
Abstract:: The dissipation of internal wave energy in the turbulent boundary layer under pack ice is determined using a time‐varying boundary layer model with an eddy coefficient closure scheme. The magnitude of the eddy coefficient is determined by the ice drift velocity, which is assumed greater than the rms water velocity...

The upper ocean internal wave field: Influence of the surface and mixed layer

Creator:: Levine, Murray D.
Abstract:: A model is developed to calculate the upper ocean internal wave spectrum as modified by the surface boundary and mixed layer. The Garrett‐Munk spectrum is assumed to describe the deep ocean wave field. The main effect of the surface and mixed layer is to align the vertical structure of the...

Sea-surface aerodynamic roughness

Abstract:: This study surveys and evaluates similarity theory for estimating the sea-surface drag coefficient with the bulk aerodynamic method. The most commonly used formulations of the aerodynamic roughness length, required by similarity theory, are examined using data sets from four different field programs. These relationships include the Charnock formulation and the...

Horizontal transport and the distribution of nutrients in the coastal transition zone off Northern California: effects on primary production, phytoplankton biomass and species composition

Creator:: Chavez, Francisco P., Barber, Richard T., Kosro, P. Michael, 1951-, Huyer, Adriana, 1945-, Ramp, Steven R., Stanton, Timothy P., and Rojas de Mendiola, Blanca
Abstract:: Conductivity‐temperature‐depth surveys during 1988 encountered strong baroclinic jets that were evident in acoustic Doppler current profiler and hydrographic data. During June and July 1988 a filament with high surface nitrate, high chlorophyll, abundant populations of neritic centric diatoms, and higher rates of primary production was evident perpendicular to the coast...
