Hyperspectral temperature and salt dependencies of absorption by water and heavy water in the 400-750 nm spectral range

Creator:: Sullivan, James M., Twardowski, Michael S., Zaneveld, J. Ronald V., Moore, Casey M., Barnard, Andrew H., Donaghay, Percy L., and Rhoades, Bruce
Abstract:: The temperature and salt dependencies of absorption by liquid water (H₂O) and heavy water (D₂O) were determined using a hyperspectral absorption and attenuation meter (WET Labs, AC-S). Sodium chloride (NaCl) was used as a proxy for seawater salts. There was no significant temperature (ψₜ) or salt (ψₛ) dependency of absorption...

Validation of Terra-MODIS phytoplankton chlorophyll fluorescence line height

Creator:: Hoge, Frank E., Lyon, Paul E., Swift, Robert N., Yungel, James K., Abbott, Mark R., Letelier, Ricardo M., and Esaias, Wayne E.
Abstract:: The Moderate Resolution Imaging Spectroradiometer (MODIS) aboard the Terra spacecraft contains spectral bands that allow retrieval of solar-induced phytoplankton chlorophyll fluorescence emission radiance. Concurrent airborne laser-induced (and water-Raman normalized) phytoplankton chlorophyll fluorescence data is used to successfully validate the MODIS chlorophyll fluorescence line height (FLH) retrievals within Gulf Stream, continental...

Model for the interpretation of hyperspectral remote-sensing reflectance

Creator:: Lee, Zhongping, Carder, Kendall L., Hawes, Steve K., Steward, Robert G., Peacock, Thomas G., and Davis, Curtiss O.
Abstract:: Remote-sensing reflectance is easier to interpret for the open ocean than for coastal regions because the optical signals are highly coupled to the phytoplankton (e.g., chlorophyll) concentrations. For estuarine or coastal waters, variable terrigenous colored dissolved organic matter (CDOM), suspended sediments, and bottom reflectance, all factors that do not covary...

Absorption and attenuation of visible and near-infrared light in water: dependence on temperature and salinity

Creator:: Pegau, W. Scott, Gray, Deric, and Zaneveld, J. Ronald V.
Abstract:: We have measured the absorption coefficient of pure and salt water at 15 wavelengths in the visible and near-infrared regions of the spectrum using WETLabs nine-wavelength absorption and attenuation meters and a three-wavelength absorption meter. The water temperature was varied between 15 and 30 °C, and the salinity was varied...

Comparison of Near-Forward Light Scattering on Oceanic Turbulence and Particles

Creator:: Bogucki, Darek J., Domaradzki, J. Andrzej, Stramski, Dariusz, and Zaneveld, J. Ronald
Abstract:: We examine and compare near-forward light scattering that is caused by turbulence and typical particulate assemblages in the ocean. The near-forward scattering by particles was calculated using Mie theory for homogeneous spheres and particle size distributions representative of natural assemblages in the ocean. Direct numerical simulations of a passive scalar...

Dynamic range and sensitivity requirements of satellite ocean color sensors: learning from the past

Creator:: Hu, Chuanmin, Feng, Lian, Lee, Zhongping, Davis, Curtiss O., Mannino, Antonio, McClain, Charles R., and Franz, Bryan A.
Abstract:: Sensor design and mission planning for satellite ocean color measurements requires careful consideration of the signal dynamic range and sensitivity (specifically here signal-to-noise ratio or SNR) so that small changes of ocean properties (e.g., surface chlorophyll-a concentrations or Chl) can be quantified while most measurements are not saturated. Past and...

Remotely sensed reflectance and its dependence on vertical structure: a theoretical derivation

Creator:: Zaneveld, J. Ronald V.
Abstract:: An exact expression for the remotely sensed reflectance (RSR, upwelling radiance divided by downwelling scalar irradiance) just beneath the surface of the ocean is derived from the equation of radiative transfer. It is shown that the RSR at a given depth in the ocean depends only on the inherent optical...

Volume scattering function of suspended particulate matter at near-forward angles: a comparison of experimental and theoretical values

Creator:: Spinrad, Richard W., Zaneveld, J. Ronald V., and Pak, Hasong
Abstract:: Narrow angle light scattering measurements were made for various sizes of spherical particles suspended in water. These were compared to calculated theoretical scattering values as derived from the theory of Mie (1908). Through measurements with different particle concentrations at angles between 0.2° and 0.7° the effect of the unscattered main...

Influence of Raman scattering on ocean color inversion models

Creator:: Westberry, Toby K., Boss, Emmanuel, and Lee, Zhongping
Abstract:: Raman scattering can be a significant contributor to the emergent radiance spectrum from the surface ocean. Here, we present an analytical approach to directly estimate the Raman contribution to remote sensing reflectance, and evaluate its effects on optical properties estimated from two common semi analytical inversion models. For application of...

Optical scattering and backscattering by organic and inorganic particulates in U.S. coastal waters

Creator:: Snyder, William A., Arnone, Robert A., Davis, Curtiss O., Goode, Wesley, Gould, Richard W., Ladner, Sherwin, Lamela, Gia, Rhea, William J., Stavn, Robert, Sydor, Michael, and Weidemann, Allen
Abstract:: We present the results of a study of optical scattering and backscattering of particulates for three coastal sites that represent a wide range of optical properties that are found in U.S. near-shore waters. The 6000 scattering and backscattering spectra collected for this study can be well approximated by a power-law...
