Scales of variability of bio-optical properties as obersved 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,...

Assessment of new production at the upwelling center at Point Conception, California, using nitrate estimated from remotely sensed sea surface temperature

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...

Surface Heating and Patchiness in the Coastal Ocean off Central California During a Wind Relaxation Event

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...

Interpretation of hyperspectral remote-sensing imagery by spectrum matching and look-up tables

Creator:: Mobley, Curtis D., Sundman, Lydia K., Davis, Curtiss O., Bowles, Jeffrey H., Downes, Trijntje Valerie, Leather, Robert A., Montes, Marcos J., Bissett, William Paul, Kohler, David D. R., Reid, Ruth Pamela, Louchard, Eric M., and Gleason, Arthur
Abstract:: A spectrum-matching and look-up-table (LUT) methodology has been developed and evaluated to extract environmental information from remotely sensed hyperspectral imagery. The LUT methodology works as follows. First, a database of remote-sensing reflectance (R[subscript]rs) spectra corresponding to various water depths, bottom reflectance spectra, and water-column inherent optical properties (IOPs) is constructed...

Analysis of a Point-Source Integrating-Cavity Absorption Meter

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,...

Atmospheric Correction Algorithm for Hyperspectral Remote Sensing of Ocean Color from Space

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...

Bottom Characterization from Hyperspectral Image Data

Creator:: Philpot, William, Davis, Curtiss O., Bissett, W. Paul, Mobley, Curtis D., Kohler, David D. R., Lee, Zhongping, Bowles, Jeffrey, Steward, Robert G., Agrawal, Yogesh, Trowbridge, John, Gould, Richard W. Jr., and Arnone, Robert A.
Abstract:: In optically shallow waters, i.e., when the bottom is visible through the water, a tantalizing variety and level of detail about bottom characteristics are apparent in aerial imagery (Figure 1a). Some information is relatively easy to extract from true color, 3-band imagery (e.g., the presence and extent of submerged vegetation),...

From Meters to Kilometers: A Look at Ocean-Color Scales of Variability, Spatial Coherence, and the Need for Fine-Scale Remote Sensing in Coastal Ocean Optics

Creator:: Bissett, W. Paul, Arnone, Robert A., Davis, Curtiss O., Dickey, Tommy D., Dye, Daniel, Kohler, David D. R., and Gould, Richard W. Jr.
Abstract:: The physical, biological, chemical, and optical processes of the ocean operate on a wide variety of spatial and temporal scales, from seconds to decades and from micrometers to thousands of kilometers (Dickey et al., this issue; Dickey, 1991). These processes drive the accumulation and loss of living and nonliving mass...

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...
