Creator:: Filippi, Anthony M., Carder, Kendall L., and Davis, Curtiss O.
Abstract:: Ocean color remote-sensing systems require highly accurate calibration (<0.5%) for accurate retrieval of water properties. This accuracy is typically achieved by vicarious calibration which is done by comparing the atmospherically corrected remote-sensing data to accurate estimates of the water-leaving radiance. Here we present a new method for vicarious calibration of...

Creator:: Gao, Bo-Cai, Montes, Marcos J., Ahmad, Ziauddin, and Davis, Curtiss O.
Abstract:: Existing atmospheric correction algorithms for multichannel remote sensing of ocean color from space were designed for retrieving water-leaving radiances in the visible over clear deep ocean areas and cannot easily be modified for retrievals over turbid coastal waters. We have developed an atmospheric correction algorithm for hyperspectral remote sensing of...

Creator:: Dugdale, Richard C., Davis, Curtiss O., and Wilkerson, Frances P.
Abstract:: Remotely sensed sea surface temperature (SST) and a model originally developed for Cap Blanc, northwest Africa [Dugdale et al., 1989], are used to estimate new production (i.e., nitrate uptake, in the sense of Dugdale and Goering [1967]) for the persistent coastal upwelling feature at Point Conception, California. Parameters required to...

Creator:: Ramp, Steven R., Garwood, Roland W., Davis, Curtiss O., and Snow, Richard L.
Abstract:: The difference between the temperature of the ocean at 4-cm and 2-m depth was continuously monitored during a cruise to the coastal transition zone off Point Arena, California (38°58′N, 123°45′W), during June 1987. The two temperatures were coincident most of the time but diverged during one nearshore leg of the...

Creator:: Leathers, Robert A., Downes, T. Valerie, and Davis, Curtiss O.
Abstract:: We evaluate the theoretical performance of a point-source integrating-cavity absorption meter (PSICAM) with Monte Carlo simulations and a sensitivity analysis. We quantify the scattering errors, verifying that they are negligible for most ocean optics applications. Although the PSICAM detector response is highly sensitive to the value of the wall reflectivity,...

Creator:: Lee, ZhongPing, Weidemann, Alan, Kindle, John, Arnone, Robert, Carder, Kendall L., and Davis, Curtiss
Abstract:: Euphotic zone depth, z[subscript]1%, reflects the depth where photosynthetic available radiation (PAR) is 1% of its surface value. The value of z[subscript]1% is a measure of water clarity, which is an important parameter regarding ecosystems. Based on the Case-1 water assumption, z[subscript]1% can be estimated empirically from the remotely derived...

Creator:: Davis, Curtiss O., Kavanaugh, Maria, Letelier, Ricardo, Bissett, W. Paul, and Kohler, David
Abstract:: Current ocean color sensors, for example SeaWiFS and MODIS, are well suited for sampling the open ocean. However, coastal environments are spatially and optically more complex and require more frequent sampling and higher spatial resolution sensors with additional spectral channels. We have conducted experiments with data from Hyperion and airborne...

Abstract:: This study uses derivative spectroscopy to assess qualitative and quantitative information regarding seafloor types that can be extracted from hyperspectral remote sensing reflectance signals. Carbonate sediments with variable concentrations of microbial pigments were used as a model system. Reflectance signals measured directly over sediment bottoms were compared with remotely sensed...

Abstract:: The propagation of downwelling irradiance at wavelength l from surface to a depth (z) in the ocean is governed by the diffuse attenuation coefficient, K𝒹(λ). There are two standard methods for the derivation of K𝒹(λ) in remote sensing, which both are based on empirical relationships involving the blue-to-green ratio of...
